Do-it-yourself impact rotary screwdriver from the starter. Impact screwdriver - how to use it correctly, and can you make it yourself?

Details of Impact Screwdriver

Naturally, today the price of an impact screwdriver depends on many factors.

As a rule, it depends on the quality, manufacturer and completeness of the tool. In the vast majority, along with an impact screwdriver, the kit includes at least two attachments - one for a Phillips screwdriver, the second for a flat slotted screwdriver.

The connecting part of the tool and the nozzle are hexagonal in shape, so when it comes into contact with a screwdriver, the nozzle engages tightly.

The presence of these attachments means that using a screwdriver you can tighten not only screws or self-tapping screws, but also work with nuts and bolts. This is convenient not only in construction or repair, but also in other areas of activity - for example, when repairing cars or scooters.

A high-quality impact screwdriver is made of chrome vanadium alloy or high-quality tool steel. Such materials allow the screwdriver to be as durable and reliable as possible. It is worth noting that cheap models of impact screwdrivers have attachments that are not always made of tool steel, but they are made from unknown alloys or metals.

Therefore, as a result, a screwdriver of this quality will not last for a long time and after a few months of use it may become unusable.

In addition to two attachments, a fairly large number of other attachments may be included with the tool, which will be useful in certain cases. By the way, a fastener screwed in with an impact screwdriver can be unscrewed only with the help of it or with the help of a powerful screwdriver, but it will not be possible to unscrew it with your bare hands.

Before buying an impact screwdriver, also pay attention to whether the body of the tool itself is durable and of high quality, since it can withstand enormous loads during operation. Purchasing a low-quality tool will lead to the fact that you will be forced to replace it with another one.

Therefore, pay attention to the manufacturer of impact screwdrivers. As a rule, those manufacturers who produce other tools and products make really high-quality products. However, if you pay attention to a screwdriver model that has a controversial “Chinese” name, most likely you need to refuse such a purchase

A high-quality impact screwdriver costs about the same as 2-3 low-quality Chinese screwdrivers, but it will last much, much longer.

Screwdriver for precision work (Precision)

An impact screwdriver is an indispensable tool in those frequent cases when the task is to unscrew a rusted or tightly tightened screw or self-tapping screw. A regular screwdriver will not work for unscrewing rusted screws or self-tapping screws, as attempts will either break the screw slot or damage the tip of the tool. Particular difficulty arises in situations where a steel screw for a screwdriver is screwed into an aluminum part. Under the influence of corrosion, a tight adhesion of the two materials occurs, as a result of which only an impact screwdriver can cope with the task.

DIY impact screwdriver

Despite the complexity of the design, such a tool can be made with your own hands. Of course, there is no need to machine a gimlet gear on a CNC router. Spare parts are available at any car dismantling center. The starter mechanism is ideal for this purpose.

The rotor with windings is cut off from the shaft.

The remaining shaft and bushing will serve as the basis of the mechanism. We grind a square on the sleeve for replacement heads.

We make a handle from a piece of pipe, and a striking heel from a powerful bolt.

After welding the structure together, the finished tool was obtained.

It may not be as presentable as a factory one, but the cost tends to zero. And the reliability is beyond doubt.

Very often we have to unscrew rusted bolts or screws. An ordinary screwdriver is practically useless in such cases. Even if you try to unscrew it with a simple screwdriver, you are guaranteed to knock off the tip and render it unusable. In this case, an “unusual” screwdriver comes to our aid, namely an impact screwdriver . Let's talk about it...

In appearance, you can immediately distinguish an impact screwdriver from a regular one. The drum has a reinforced steel body and is several times larger than its “brother” in size. The kit usually includes 2 or 4 bits (cross and flat). The bits are inserted in the same way as into a regular screwdriver.

The impact screwdriver has a torsion switch (reversible), usually you still use it to unscrew it, but if you need to tightly tighten any part, the reverse will come in handy.

Table of contents:

Operating principle

The principle of operation of an impact screwdriver is very simple - during an impact, the bit rotates in the required direction, and not at all by much (1-3mm), but these millimeters are quite enough to knock off a stuck bolt. Next, you can use a regular screwdriver. The main purpose is the initial phase of unscrewing, when it is impossible to do it manually.

How to use an impact screwdriver? Having previously set the reverse on the screwdriver, carefully place the bit on the stuck bolt and start hitting with a hammer until the bolt moves from its dead point. If you have a screwdriver on your household, it can easily replace an impact screwdriver. As you can see, the impact screwdriver works simply and effectively.

How to choose the right one

Compare your needs and the financial threshold for purchase. Familiarize yourself with the types and technical characteristics of screwdrivers.

Varieties

Difference by type of food:

• battery-powered The advantage is freedom of movement. The disadvantage is depending on the battery capacity;
• network. Can only be used where electricity is available;
• hybrid. They work from the network and from batteries.

Types of battery screwdriver shapes:

• straight. This device is easy to put in your pocket. But it may be inconvenient when working in a narrow place, when the fastening hole is on the side surfaces;
• L-shaped. This shape is similar to a pistol. Very easy to use. But you can’t put such a screwdriver in every pocket;
• T-shaped. It can be used to tighten and unscrew fasteners with a completely discharged battery;
• universal. This form is very convenient both for transportation and use. Because it can be changed from an L-shaped version to a straight one and vice versa. The only drawback is the wear and tear on the rotating mechanism.

Cordless screwdrivers are classified into household and professional. The latter are distinguished by greater power due to high torque and rpm.

Models in high demand

There are a number of the most popular models for home and domestic use:

• household screwdriver Makita 6723 DW. Comes with a convenient case and 80 attachments. Charges in 5 hours;
• household screwdriver Bosch PSR Select. 12 nozzles. Thanks to the Bosh EasySelect system, no attachments will get lost. Charger with indication and self-shutdown;
• household screwdriver Sparky Professional GR 3.6Li. Cheap and light. Weighs 300 grams. Has a charge indication;
• professional screwdriver Zubr Transformer-M ZO-7.2-Li KN. Works like a screwdriver. Speed ​​270 and 870. Spindle lock. 2 batteries included;
• professional screwdriver Makita TD021DSE. Screws and drills. Has a shock twisting mode. RPM from 0 to 2300;
• Hitachi WH7DL professional screwdriver. Has the highest torque of 25 Nm. Rotation speed 2400 rpm.

Homemade drums

Many people wonder whether it is possible to make an impact screwdriver with your own hands. You can, but you should think carefully before doing this. The hammer or push screwdriver is made of special alloy steel. It should be impact-resistant, but it should not be fragile. Mechanical processing of such steel at home is hardly possible; this requires a special tool. To transmit the shock impulse to the turning mechanism, the mating parts must have a certain curvature. They can only be turned on a milling machine.

Some designs use bevel gears for the torque transmission function. Replaceable attachments require a self-centering chuck or something similar. Alas, all these details cannot be done at home “on your knees”. You can make some kind of homemade impact screwdriver using softer materials. But in this case, there is a high probability that after several blows to such a device it will become unusable and go to waste.

Without special materials and skills, you can probably only make a handle for a screwdriver with your own hands. Some models have a standard plastic handle. It often cracks, and craftsmen replace it with wood of their own making.

This tool is an indispensable assistant for a repairman. They can unscrew not only screws, screws and self-tapping screws. By securing a hex adapter in the chuck, you can use heads of various sizes as a socket to loosen the nuts.

Step-by-step production

Many craftsmen make a percussion unit with their own hands, and claim that this work does not require any exceptional knowledge or additional skills. You just need to follow the step-by-step instructions.

• First you need to take a rotor from any motor. Remove all present elements except the bushing and shaft.
• Place a piece of steel tube on the surface of the sleeve, which will eventually become a handle.
• A nut is inserted on the other side. It is this that helps prevent damage to the handle during physical impact.

• Next, the shank is sawed off, to which the bits are mounted.
• The last stage of work is to connect all the elements together by welding.
• The device is ready for use. It looks, of course, not as presentable as the factory models, but in terms of service life it can be much stronger.

If you follow all the steps correctly, you will get a makeshift impact screwdriver. As it turns out, making it is not as difficult as it might seem at the very beginning of the work. There is no need to use special drawings and markings. But if you have any doubts, it is better to contact a professional.

How to use an impact screwdriver

To make the unscrewing process as simple and high-quality as possible, it is enough to avoid irreparable mistakes and follow a number of separate rules:

1. The fastener is pre-prepared for unscrewing, so it is cleaned of visible rust and wiped with a rag. The joint is then coated with a special chemical, such as WD-40, a highly effective cleaner. Brake fluid and kerosene perform well.
2. Next, you need to fix the tip in the slot, maintaining strictly perpendicular placement relative to the screw head.
3. Then you should hit the end of the handle with a hammer with approximately medium force.
4. The blows are repeated until the screw head begins to move relative to the axis. Try to check the propeller's progress after each blow.
5. Unscrewing is completed using a regular screwdriver.

If the tool is equipped with reverse, many experts recommend setting the tightening mode after each movement of the head, repeating the blows several times, and then unscrewing the hardware again. This is explained by the fact that with this approach, rust elements are removed from the threads particularly well.

To avoid trouble, it is recommended to follow safety precautions:

It is important to first put on good work gloves or gloves on your hands, which will prevent the handle from accidentally sliding during processing. Don't put too much effort into your punches. You can get by with a regular hammer weighing up to 500 grams. Strikes should remain light

Do not tilt the hammer, as the hammer can easily slide off the screwdriver, which will cause additional problems.

Impact screwdriver: purpose and operating features of the tool

Locksmith work around the house or professional repair and production activities are not complete without the use of tools. Even people who are accustomed to using the services of professional workers to perform everyday repair tasks should have standard tools in their arsenal: a hammer, a screwdriver, pliers and other basic tools.

This article will talk about one of the tools called an “impact screwdriver”, which is not classified as elementary, but helps to cope with difficult work of unscrewing “stuck”, rusty bolts and screws. Let's look at the features of this tool, its purpose, the need for it on the farm, the advantages and disadvantages of operation, and we'll tell you how to make a functional device yourself.

A screwdriver is an elementary-class tool that has a long history of existence, is used in various fields of work, and allows you to unscrew screw-type elements without using significant force through manual action.

For many years, locksmiths and professional workers have been using an impact screwdriver, the purpose of which is to unscrew rusty or tightly screwed bolts and screws.

In such situations, a traditional device is not used, since breaking off an “ingrown” screw requires a lot of effort, which is not always successful, and the process may result in damage to the tool. An impact screwdriver will help you move the screw from a dead point.

This tool differs from the traditional device in its reinforced metal body and the presence of monolithic, durable attachments for different types of reamings at the end of the hardware.

A special feature of the functioning of the mechanism is the reverse process under impact force: the bit of the device rotates slightly under pushing pressure, allowing the fastener to be rotated a few millimeters, which is enough for further unhindered unscrewing with standard tools.

The use of an impact screwdriver is important at the initial stage of unscrewing problematic hardware, as well as at the final stage of screwing in fasteners, to eliminate the possibility of them loosening during operation of the connected device.

Screwdrivers have differences in design, technical characteristics and properties, which determines their functionality.

The simplest variety is a type of tool known to many since ancient times, which is a device with a hexagon inside, a monolithic core and a massive handle with a heel at the end, intended for striking with a hammer.

Modern designs of this class are characterized by the presence of a rotating mechanism inside, called impact-rotary screwdrivers. When choosing such products, you should give preference to models that are equipped with reverse motion, which allows you to use the device not only to “break” a problem bolt from its dead point, but also to tighten hardware during their installation.

The tools also differ in the quality of the body: the most reliable and durable nowadays are usually called devices whose frame is made of high-quality steel, and the handle has pads made of polyurethane or rubber, which makes it easier to hold the screwdriver when used for its intended purpose. To simultaneously implement these tasks in a tool, manufacturers use two versions of devices:

1. They leave the dimensions of the steel case unchanged, supplementing it with overlays, which is reflected in the final dimensions of the product. Such screwdrivers are considered very reliable, durable, have a long service life, however, they are not suitable for use in hard-to-reach places.
2. They manufacture small-sized devices with linings from high-quality rubber materials by reducing the diameter of the steel frame. It is easy to work with such screwdrivers in narrow openings, however, the solution to the problem with hard-to-reach places is reflected in a decrease in the reliability of the device and its strength.

When selecting a product, it is also important to take care of its versatility.

Products that are equipped with a universal-class holder, which allows for the use of different-sized nozzles for various types of heads of hardware products, are considered more expensive.

The kit often includes several standard attachments, however, if the need arises, the user will be able to equip the screwdriver with additional bits, which will expand its functionality.

An important criterion when selecting bits is their high-quality performance: bits should be selected not only by calibration, but also taking into account the strength standard that affects their service life.

An impact screwdriver, like any other product, has its operational pros and cons. The advantages of using impact screwdrivers among professionals include:

1. Possibility of sole operation of the device, which is not typical for old-style instruments of this category.
2. There is no need for brute physical force to unscrew problematic hardware.
3. Rational gradation of impact energy, which contributes to the rapid “breaking” of the bolt, with minimal risk of damage to the working surface.

There are practically no disadvantages to rotary-impact screwdrivers, with the exception of precedents when the purchased unit belongs to the category of inexpensive goods of dubious quality.

Inexpensive, low-quality devices can quickly become unusable if they are based on low-strength metal: under the influence of impact forces and regular friction, the gears, return mechanism and bits wear out.

Purchasing a high-quality tool from well-known manufacturers eliminates the occurrence of unpleasant precedents; the device will serve, if used correctly, for a long period.

Some users who do not often deal with plumbing repair work believe that a hammer-type screwdriver can be a worthy alternative to an impact screwdriver.

This assumption is incorrect, since these devices differ initially in their design, purpose and technical features.

An impact screwdriver and a screwdriver have a common feature: both mechanisms are designed for unscrewing hardware, their impact force is perpendicular to the line of rotation.

A distinctive characteristic is the nature of the torsional force:

1. The use of a screwdriver predetermines the possibility of initial failure of hardware that has rusted or is firmly “grown” into the working surface.
2. An impact screwdriver is designed for unscrewing already rotating hardware: it is used to reduce the physical effort of a person to remove a spinning screw.

Impact screwdriver

In terms of functionality, a screwdriver is an effective, modern tool for high-quality and simple removal of hardware after it has been torn off using an impact screwdriver. Products should not be positioned as interchangeable; their practical application has a distinctive position.

An impact screwdriver is not an essential tool, so for many consumers the question of how to properly use the device to unscrew problem bolts is more than relevant.

A user manual is included with the toolkit, if it is certified and belongs to the category of quality products from reliable manufacturers; however, inexpensive screwdrivers may not be supplied with such regulations.

It is possible to figure out on your own how to use an impact screwdriver using the method of experiments and calculations, however, such tests can cause the tool to break if used incorrectly, or damage the working surface when trying to unscrew the hardware, which is also not always acceptable for the work performer. Operation of the product requires strict adherence to the manufacturer’s regulations, which will allow you to effectively cope with the task.

It is not difficult to use an impact-turning screwdriver in practice, since the tool has a vectorial purpose to reduce human effort when it is necessary to remove rusted screw hardware and make the unscrewing process as easy as possible.

To achieve the desired result, you should follow the following basic rules:

1. Before proceeding with the actual removal of screw hardware, it is worth preparing the working surface. The process involves removing dirt and obvious rust from the surface of the hardware and the area around it.
2. Treat the loose hardware with a chemical that helps remove rusty deposits. For this purpose, professionals recommend using WD-40 cleaner; however, kerosene, gasoline or brake fluid also does a good job.
3. Next, you should start working directly with an impact screwdriver, having prepared the tool for use, and a regular hammer of medium size.
4. When working with an impact screwdriver, you must begin by fixing its tip in the slotted head of the hardware, maintaining the perpendicularity of the position of the tool relative to the axis of rotation of the element being unscrewed.
5. Strike the end part of the handle with a hammer. The impact force should be of medium intensity to avoid breakage or damage to the slot. At the same time, you need to monitor the hardware so as not to miss the moment when it starts to rotate.
6. As soon as the screw moves from its dead point, put the tool down. Continue unscrewing the hardware using a standard type screwdriver.

When operating products equipped with a reverse motion, professionals advise adjusting the tightening mode of the fastener after the first shift of the screw head. The procedure will allow you to tighten the element after several light blows with a hammer, which will facilitate more effective removal of rust over the entire surface of the hardware. After this procedure, unscrewing the screw will be much easier.

Features and principle of operation

The impact screwdriver was popular back in the days of the Soviet Union. At that time, it was made in the simplest form with the presence of a monolithic core. After some time, this device underwent a slight modification, and screwdrivers of this type began to be equipped with a hexagon near the tip, and in some models it was installed on the handle. That is why power screwdrivers have the ability to transmit rotational force from the key. To carry out successful work with the described device, it was necessary to use a double workforce. In simple terms, one master supported the sting and at the same moment created rotation using pliers, and the second made superficial blows with a heavy object.

In the modern world, a name such as an impact screwdriver implies a modified device that can unscrew any bolts. Classic models from the past have lost public interest and are no longer in demand. In current modifications, the impact-rotating unit is located in the handle, the sting is mounted on the gear. The movement of the device begins under the influence of a heavy object. The clip moves along the specified axis, due to which the fasteners shift by a couple of degrees. This distance is enough for the connection to loosen, after which the bolts are unscrewed. The return of the impact unit to its original position occurs due to a special spring located in the structure. Only one manpower is needed to operate this model of power screwdriver.

You should familiarize yourself with the technical specifications of impact screwdrivers. There is no point in talking about the quality of the device and the reliability of the metal used in production. Popular brands will never use low-quality materials to make their products.

An important factor in the design of an impact screwdriver is the presence of reverse. It is he who expands the capabilities of the impact device

It is important to pay attention to the design of the handle. The presence of rubber or polyethylene layers in the body will allow you to hold the unit in your hand. In addition, this is a special safety condition

In addition, this is a special safety condition.

Manufacturers use several factors when developing each impact driver model.

• The dimensions of the case do not change, but its use in difficult and crumpled conditions is strictly prohibited.
• Allows you to increase the area of ​​use and increase the level of convenience during operation. But then the reliability of the tool itself may suffer.

When making a choice between one unit or another, you need to understand the features of the upcoming work, with all possible difficulties and nuances, and only after that purchase a power screwdriver. It is worth noting that purchasing one screwdriver is extremely illogical. In this case, tool manufacturers found solutions and began to produce sets with several nozzles of different sizes and tips on the world market.

Specifications

If you are going to purchase a screwdriver in a store, be prepared to understand the key technical characteristics and equipment of a particular model.
When reviewing these characteristics, it is not necessary to talk about the build quality and reliability of the material from which the tool is made. Trusted companies never use low-quality steel to produce such products.

You should pay attention to the presence of a reverse, which significantly expands the basic capabilities of the device, allowing you not only to unscrew rusty connections, but also to firmly tighten the screw in the place where it is needed. The next important factor is represented by the design of the handle, which is intended to hold the device and the body

If there is a polyurethane, rubber or polyethylene lining on the body, it is much more convenient to hold the screwdriver. If the pad has a “bulge” in the heel part, this has a positive effect on operational safety. In most cases, screwdriver manufacturers follow two paths:

The next important factor is represented by the design of the handle, which is intended to hold the device and the body. If there is a polyurethane, rubber or polyethylene lining on the body, it is much more convenient to hold the screwdriver. If the pad has a “bulge” in the heel part, this has a positive effect on operational safety. In most cases, screwdriver manufacturers follow two paths:

• The dimensions of the case do not change, while the screwdriver remains highly reliable, but cannot be used in extreme and cramped conditions.
• To expand the scope of application and improve ease of use, the dimensions of the metal case are reduced, although the reliability of the tool suffers because of this. When choosing the ideal solution, you should carefully weigh all the features and only then make a purchase.

It is no secret that popular brands produce screwdrivers along with an additional set of attachments, because without these elements the tool is simply ineffective. The screwdriver comes with a holder for standard bits, and the kit also includes several universal bits.

The market for such products is overflowing with attachments for various splines and hexagons. When purchasing these parts, be careful and consider the build quality. This is a very important parameter that determines the reliability of operation and service life of the screwdriver.

Advantages and disadvantages of the tool

Like any tool, such a screwdriver has its advantages and disadvantages. Working with it, experts note a number of key advantages:

• Effective distribution of impact energy.
• Much less need for physical effort. The classic version requires stronger and more intense blows.
• Possibility of operation without the help of a partner.

As for the disadvantages, they are practically absent, however, if the basic rules are not followed during operation, such disadvantages often appear:

• Possibility of damage to the impact-rotating unit. The version of the simplest impact screwdriver is made of a monolithic structure, so its service life exceeds the modernized solution. To prevent unexpected damage, it is enough to avoid too strong impacts on the impact-rotating mechanism.
• Tendency to wear out quickly. Gear teeth and races are very exposed to friction associated with shock loads. With prolonged use, their service life deteriorates significantly.

Advantages and disadvantages

The most important advantage of working rotary screwdrivers is the effective use of impact force and its versatility. To work with such a hand tool you will need to apply much less force than when working with a hammer.

The disadvantage of the design is that the body is not monolithic. Therefore, the impact power should be calculated correctly. The mechanical part of the impact driver is subject to wear.

And another disadvantage is the price. Such a hand tool, produced by a well-known manufacturer, will be quite expensive.

What materials are impact screwdriver handles made from?

The handle of an impact driver serves both as a handle and as a housing for the mechanism. In addition to structural strength (it is necessary to hold the mechanical part), the handle also serves as protection for the master’s hands.

Steel body-handles.

This tool is classified as professional. The durable steel housing also serves as a housing for the rotation mechanism. The absence of extra layers on the handle allows you to place the screwdriver in hard-to-reach places. The one-piece design provides precise force dosing and excellent process control.

Such tools are usually supplied in the form of sets with various attachments. All the same, the design is not monolithic, and therefore it can be supplemented with a universal cartridge for standard bits.

Only when purchasing additional attachments should you remember the increased loads and not skimp on quality.

Component handles

The body of the screwdriver mechanism is covered with a rubberized shell. The material can be different - polyurethane, rigid polyethylene. The main thing is to ensure shock damping and a firm grip in the hand. In the heel part of the handle, a ridge in the form of a fungus is usually made. As with a bolt, this provides additional protection for the hand in case of an inaccurate hit with a hammer.

The soft handle cannot be part of the mechanism, the load is too great. Therefore, the issue of the size of the power unit (and therefore the safety margin) arises acutely. If the mechanical part is left powerful and large, as in products with a steel handle, the overall dimensions of the screwdriver will not allow working in cramped conditions.

Reducing the size reduces the strength of the tool, but makes it more convenient.

You can always choose an option that meets your needs.

Impact screwdriver vs impact driver

It is important to remember that an impact driver and an impact driver are not a replacement for each other. The screwdriver also imparts impact force in a plane perpendicular to the axis of rotation. This, by the way, is what distinguishes it from an impact drill, which creates shock loads along the axis of rotation. However, a screwdriver only facilitates the process of unscrewing and tightening an already rotating screw.

These tools perform completely different tasks:

• The impact-turn screwdriver is designed for the initial “breaking” of a “stuck” screw from its place.
• An impact screwdriver is designed to reduce the required pressure on the tool during operation.

After studying the features of impact screwdrivers, it is recommended to watch videos that provide reviews of various models. This will help you make the right choice when purchasing and become the owner of a useful and reliable tool.

The need to use an impact screwdriver often arises. It is useful to know about the operating principle of this tool for anyone who is faced with the need to unscrew rusted screws and bolts.

The impact device differs from an ordinary screwdriver in its large and reinforced metal body. The package usually includes flat and cross bits. They are installed in the same way as on a regular screwdriver.

The impact-type device is equipped with a torsion regulator, which is why this tool is also called reversible.

Distinctive feature

This model differs from an ordinary hand-held device only in its reinforced body, which is made of metal with an admixture of chrome vanadium alloy and is thick. It is several times larger than a traditional instrument. Thanks to the switching of torque, the product is called reversible.

The screwdriver comes with 2 to 4 bits. They have a cross and a flat tip. The attachments are installed according to the same principle that is used when working with simple screwdrivers.

The most important distinguishing feature is the sting:

• it runs the entire length, starting from the slots and to the end of the handle;
• made from a single piece of metal;
• made of high quality steel.

When producing the tip, the use of joints and welding joints is unacceptable. This part of the screwdriver has the shape of a hexagon, and on the heel of the handle of the device there may be a square or hexagonal figure for a key.

When choosing nozzles, first of all you need to pay attention to what metal they are made of. The most durable alloys are: The manufacturer includes Russian-language instructions for the hand tool

The manufacturer includes Russian-language instructions for the hand tool.

How to use?

For many people, especially those who have picked up an impact screwdriver for the first time, many questions arise about the principle of its operation. That is why, before you start using the tool, you need to read its detailed instructions and understand how to use it correctly.

• Before starting work, you should carry out some manipulations with the fastener. It must be cleaned of possible contamination. To do this, just use a sponge or brush.
• A few drops of brake fluid drip onto the surface of the fastener. If it is missing, you can use other means, for example, WD40 lubricant, which is used in the automotive industry, antifreeze, kerosene or any machine oil. After applying the lubricant, wait a couple of minutes. This time will be enough for the liquid to get inside the fastener.
• Next you need to select a nozzle. As a rule, impact screwdriver sets come with several different types of bits, and by trying them on you can find the ideal bit size.
• Afterwards, you need to install the nozzle into the shank and fix it in the base of the fastener.
• Then apply several blows with a hammer on top of the screwdriver. It is worth noting that when applying force, the screwdriver should be held in such a way that its axis coincides with the axis of the fastener being screwed on, that is, it is located along the slots.

During prolonged use, the impact screwdriver may become damaged. But this does not mean that you need to buy a new model. First you need to disassemble the tool and determine the cause of the breakdown. In most such cases, all you need to do is replace the rotor

After repair operations, it is important to correctly assemble the unit and check the operation in action.

If the element to be unscrewed can be dismantled, then the screwdriver system can be switched to reverse and again make several strong blows. As soon as you feel that the fastening element is being unscrewed from the base, you can remove the impact screwdriver and then use a regular model with a simple tip.

Despite the fact that an impact screwdriver is the most common tool in the manufacturing and construction industry, it is not always able to help the craftsman. Especially when old corrosion has stuck between the fasteners and the base. To solve this problem, you will have to drill.

How to use the shock-rotary response, see the video below.

Instructions for use

To successfully unscrew a rusted fastener, it is enough to treat it with a rag or a special product in time. Then the screwdriver is installed on the head of the hardware, preferably perpendicular to it. At the next stage, several blows are made with a hammer on the end of the screwdriver. The success of the upcoming event directly depends on the strength of the tool in the worker’s hand. To eliminate the possibility of your palm sliding along the handle, it is enough to wear a glove, which will significantly reduce the risk of serious hand injuries.

If the fastener changes its direction angle relative to the axis, it is enough to make a few more intense blows, and then change the operating mode to tightening. In this case, you will effectively get rid of rust and significantly simplify the remaining work of unscrewing. If the fastener moves out of place, it can be removed using a regular screwdriver.

It is possible that after performing the above actions, the hardware will not change its direction and will remain in the same position. To solve the problem, simply treat the connecting fasteners with high-quality brake fluid, waiting about 30 minutes. Under the influence of such a “bath”, the upcoming dismantling will be as successful as possible, even if the fasteners are very rusty.

If this does not solve the issue, you will have to break out the fasteners. In this case, it is advisable to use a strong hammer and carefully follow the dismantling instructions.

To carry out dismantling work, you should use the following tools:

• Impact screwdriver.
• With a hammer.
• With a rag.
• Brake fluid.

Impact screwdriver how to use video

Greetings! In this video I will tell you and show you in practice how to use an impact screwdriver. That is, its use in practice, in order to carefully unscrew soured bolts and at the same time preserve their condition. As a rule, we need such a tool for unscrewing bolts with a head: for a cross (plus), for a flat screwdriver (minus), for asterisks and hexagons

Due to the fact that such bolts should be unscrewed carefully - so as not to damage (lick) the edges, otherwise. You'll have to suffer quite a bit to unscrew such a bolt.

And for these purposes, an impact screwdriver is ideal. Because she loyally unscrews and breaks the bolts into motion. But you will learn about all this in the video itself!

There are times when it is impossible to unscrew a bolt or old self-tapping screw with a traditional tool. At this point, only an impact screwdriver will help you.

This model is suitable for loosening a tightly tightened bolt or tightening a screw. Most often, the tool is used to secure a car door. If you tighten it with a simple screwdriver, the screws will soon loosen and come out.

Types of impact screwdrivers

Nowadays you are unlikely to find the classic impact screwdriver that our fathers and grandfathers used on store shelves. This name refers to a modern version of the instrument.

The working mechanism itself is located in the handle of the screwdriver, and the tip is connected to a gear that has beveled teeth.

As soon as the hammer hits the heel of the screwdriver, the cage begins its movement, starting the movement of the tip due to the presence of a gear. Due to this, there is sufficient force to destroy the rust and turn the bolt or nut just a little, after which you can use the usual tools that are available for unscrewing.

The impact driver cage returns to its original position using the spring in the mechanism.

You can easily handle it alone and it’s not difficult at all. This screwdriver works extremely efficiently, providing both translational and rotational motion to any rusted hardware, allowing you to unscrew it as quickly and gently as possible.

Using the tool at work

Before starting work, you need to clean the screw head as much as possible and especially the slot into which the working attachment is inserted. To do this, you can use a brush with metal bristles. Then apply a drop of brake fluid to the head to wet out the rust. Can also be used:

• universal aerosol lubricant WD-40 or any equivalent;
• antifreeze;
• kerosene;
• any machine oil.

Screw the cartridge with the nozzle into the slot as tightly as possible

If the screw moves out of place, switch the device to reverse rotation and again make a few gentle blows. You can repeat this operation several times, periodically adding a little lubricant to loosen new layers of rust. Then you can use a screwdriver or hand tool to completely unscrew the hardware.

Unfortunately, even such a breaker screwdriver does not always help. The mating parts are sometimes so affected by corrosion that when you try to unscrew the screw or screw, it simply bursts. In this case, the only way to remove it is drilling.

Purpose and areas of application of cordless screwdrivers

The cordless screwdriver is used for screwing and unscrewing various fasteners into non-solid materials, such as wood. The screwdriver's battery is built into the handle, so the tool is small in size. The device can be used where there is no need to drill or tighten fasteners, to work in narrow places and openings where a screwdriver cannot fit.

The cordless screwdriver is used in assembling furniture, installing windows, repairing household and computer equipment, car maintenance, and performing minor household work.

What is an impact screwdriver and how should it be used?

Welcome! An impact screwdriver is what people call it, and its full name is: “Impact rotary screwdriver.” Recently, we have been asked questions about this unit very often, someone asks: How should it be used? For some people are interested in its purpose, but for others they just need to find out how much it costs and what types it has. Let's begin to analyze these issues.

What is an impact screwdriver used for?

It is needed to loosen the tightening, as well as to strongly tighten the nuts that require this by design, for example, the screws that secure the door lock on the car body must be tightened only with an impact rotary screwdriver, otherwise, when tightening these screws with a regular screwdriver, during operation car (over bumps, potholes, etc.), the tightening of these screws will weaken and eventually they will come out completely.

Note! The photo just above shows the lock and the very screws that need to be tightened with an impact screwdriver (The screws are indicated by arrows). The photo was taken using the example of a VAZ 2109 car!

How to use an impact screwdriver?

Everything is very simple! Take this screwdriver in your hands and, along with it, also take a hammer, or something else with which you will hit the impact-turning screwdriver.

When you have collected all the necessary things, apply the impact screwdriver to the screw that you need to unscrew, and after you have applied it, make one blow with such force that you think will be needed to unscrew this screw and not deform the surface.

After one or several blows have been made, put this screwdriver aside and then completely unscrew this screw that you previously unscrewed using a rotating impact screwdriver.

To tighten the screw you need, do the same operation but only in reverse order, that is: First, tighten the screw until it starts to turn with a little force, and then take the screwdriver in your hands and, by hitting it with a hammer, tighten this screw until stop

Note! Do not use a regular screwdriver to tighten the screw in need of impact until it stops, because if the screw is screwed all the way with a regular screwdriver, then when hit with a shock rotary screwdriver, the screw can damage the car body, thereby being screwed in more strongly!

How much does an impact screwdriver cost?

In fact, it's different everywhere. But this is understandable, because each owner of his store sets his own price for the product, and not the one that is written somewhere, let’s return closer to the question. If you take a screwdriver only for yourself and for your car, then the most ordinary impact screwdriver will do, which will cost you 200-500 rubles.

And if you are a service station worker and you need a screwdriver to be more convenient and to unscrew screws faster, then your price range starts from 600 and ends at 3,700 rubles.

Note! The entire price range is only approximate, and in most cases it happens that service station workers use an impact screwdriver purchased for 200 rubles, and the owners of their cars use a screwdriver whose price reaches 2100 rubles and more!

What types of impact screwdrivers are there?

The most basic type of screwdriver comes in the form of a regular bit, how to use it was written a little higher, and the greatest value of this screwdriver lies in its price, which is no less than 300-900 rubles.

The next type is a screwdriver in the form of a regular screwdriver, that is, outwardly it is no different, but inside it has a special mechanism installed that helps in the right situations to use it as an impact screwdriver, and in unnecessary situations just like a regular screwdriver. Its price range fluctuates a little higher and sometimes even reaches 3,000 thousand rubles, and starts at approximately 800 rubles per piece.

Features of the work

The principle of using an impact screwdriver.

In order to make the unscrewing process easier, rusty fasteners should be wiped in advance with a rag soaked in brake fluid. Afterwards, the screwdriver should be installed on the head of the hardware; if possible, this should be done strictly perpendicularly. Then the end of the tool should be hit with a hammer. How successfully the work will be carried out, in this case, depends on how firmly the tool is held in the hand. You can prevent the possibility of your palm sliding along the handle of the tool by wearing a glove; this, among other things, will protect your hand from possible injuries.

After the fastener has rotated a little around its axis, it is necessary to make a few more blows with a hammer, and then switch the tool to the twisting mode, applying a few more blows. This will remove rust from the threads, which will make further work on unscrewing easier. After the fastener is moved from its place, it can be removed using a regular screwdriver.

Converting hammer impact energy into torque.

In some cases, even after all the work described above, the hardware cannot be affected, and it must be treated again with brake fluid, leaving it in this state for a period limited to 30 minutes. Such a “bath” should facilitate faster dismantling of even the most firmly reinforced fasteners. If after this it was not possible to remove it, the fasteners will have to be broken out. To carry out the work more efficiently, it is also necessary to choose the right hammer; such recommendations are given in the instructions from the screwdriver manufacturer.

Tools and materials for work:

• impact screwdriver;
• hammer;
• rags;
• brake fluid.

Some craftsmen make screwdrivers on their own, for this you will need a rotor from an electric motor, from which everything must be cut off so that the bushing and shaft remain. A piece of steel pipe should be placed on the sleeve, which will become the handle. A nut must be inserted into the scrap from the opposite end, which will not allow the handle to break. After all the parts are welded.

Basic rules for working with the tool, what you need to know

Many people wonder how an impact screwdriver works. The hand tool is very easy to use. At the moment of impact, the nozzle rotates in the required direction by 1-3 mm. This twist is enough to remove the old rusty bolt. After which you can use a traditional tool.

When starting work, you need to set the reverse. Then place the bit on the old bolt. Then begin a series of hammer blows until it moves.

If you have already used an impact screwdriver, then you will only have to use it again to screw it in.

Operating principle of the tool

Among the tools necessary for work, the impact screwdriver is in a somewhat special position.

On the one hand, it is a hand-held tool, usually made of high-quality steel; on the other hand, it is truly a unique tool, and this uniqueness lies in its special properties.

In this somewhat massive and frankly heavy instrument with really special properties, two points are important:

• special design can withstand heavy loads
• work efficiency in unusual conditions

The screwdriver consists of a body, a rotating head and interchangeable attachments. The body is made of high-quality tool steel, but with the exception that, unlike high-carbon brittle steels that are susceptible to impacts, used for the manufacture of metal-cutting and woodworking tools, an alloy that can easily withstand impacts is used in the manufacture of the handle.

The connecting part, or the rotating head of the screwdriver, allows it to rotate under the influence of an impact and rotate to a certain angle; in most cases this is just a rotation of 2-3 mm, this is quite enough to move the “welded” screw.

The third component of the impact screwdriver kit is the replacement bits supplied with the tool. These are, as a rule, two types of nozzles with a cross and a flat head.

Now that the composition of the tool is known, it doesn’t cost anything to reveal the operating principle of an impact screwdriver. The main purpose of the tool is the impact-rotating effect on a difficult-to-unscrew screw, screw, or self-tapping screw.

The assembled tool is inserted into the head of the screw, so that the nozzle fits tightly into it; with a light blow of a hammer on the back of the screwdriver, simultaneous action occurs in two planes: straight along the axis of the screw and a rotary movement to the side.

Thus, the screw is displaced along the entire surface of contact with the body of the part or fastening element. This action destroys the rust and releases the screw threads.

Thus, an impact screwdriver, the operating principle of which is based on multi-vector movement, is an indispensable tool for any locksmith workshop.

Despite the fact that the body is made of durable chrome vanadium alloy, when working with an impact screwdriver you need to know a few rules:

• The operating principle of an impact screwdriver, which is based on simultaneous rotation and impact, must be tightly inserted into the screw head, otherwise the slot will simply curl up, and further removal of the screw will be very problematic.
• To achieve the best result, it is necessary to “prepare” the screw to be removed - moisten it with automobile brake fluid or kerosene; these liquids penetrate deep into the joint and make it possible to remove the screw with less effort.
• When working with an impact screwdriver, you do not need to apply excessive force; it is enough to have a standard hammer of 300 or 500 grams.
• You need to strike lightly, but firmly, without tilting the hammer and the butt of the screwdriver to the side, the blow should be hard.
• After each blow, it is recommended to check the screw for movement; as a rule, one or two blows are enough for the screw to give way.
• During operation, the screwdriver must be held tightly in your hand, and under no circumstances should it be allowed to rotate or change its angle.

Using an Impact Screwdriver

And since when working with an impact screwdriver, as well as when working with any tool, you must follow safety rules, it is recommended to carry out all work wearing protective gloves.

They most likely will not save you from being hit with a hammer if you miss the screwdriver, but it will definitely be more convenient to hold the tool.

Thus, the use of such a special tool as an impact screwdriver can significantly reduce the time and effort when removing difficult-to-release screw connections.

In fact, this is a very convenient and necessary tool in the workshop arsenal.

The action of the device in question is based on the fact that the rotation of the bit is limited to one to three millimeters, but this is enough for the purpose of moving a rusted and stuck fastener. Then you can use an ordinary screwdriver. That is, the purpose of the impact tool is the initial stage of unscrewing, when the rusted bolt does not give in.

You don't know how to use an impact screwdriver correctly and for what purpose is it needed? With the help of our article you can find answers to all your questions.

There are times when it is impossible to unscrew a bolt or old self-tapping screw with a traditional tool. At this point, only an impact screwdriver will help you.

This model is suitable for loosening a tightly tightened bolt or tightening a screw. Most often, the tool is used to secure a car door. If you tighten it with a simple screwdriver, the screws will soon loosen and come out.

Peculiarity

To make the unscrewing process simple and easy, the old fastener must be moistened with brake fluid in advance using a rag. Then you should put the nozzle on the head of the bolt strictly along a perpendicular line and hit the handle of the screwdriver.

Successful work will depend only on how firmly you hold the tool in your hand. To prevent the tool from slipping and to protect your hands from damage, you must wear a glove.

After the fastener moves a little, you will need to make a couple more blows, and then switch the hand tool to the twisting mode, applying a few more translational movements with the hammer. This manipulation will help get rid of rust. This will make the process easier. Once you can get the bolt out of the way, you can use a traditional screwdriver.

When this manipulation does not help, you will have to resort to removal using a crowbar. To achieve greater efficiency, you need to choose the right hammer.

The most important advantage of working rotary screwdrivers is the effective use of impact force and its versatility. To work with such a hand tool you will need to apply much less force than when working with a hammer.

The disadvantage of the design is that the body is not monolithic. Therefore, the impact power should be calculated correctly. The mechanical part of the impact driver is subject to wear.

And another disadvantage is the price. Such a hand tool, produced by a well-known manufacturer, will be quite expensive.
