Impact screwdriver - rating of the best, how to use it, make it yourself and disassemble it?

A common tool is an impact driver. It is important to understand what the advantage of the product is and the difference from a conventional design, why professionals choose an impact-rotary device and how to choose the right high-quality model in order to use it for many years.

What is an impact screwdriver?

This is a tool adapted for a specific type of work. A power screwdriver is a general technical mechanical device that is correctly called an impact screwdriver. It is used both in production and at home for carrying out household repair work. The range and functionality of such tools is regularly expanded.

Impact screwdriver device

The unit is simple in design and consists of a few parts. Describing what an impact screwdriver looks like when assembled and disassembled, we note that the main part is made of high-strength steel. The handle may have a rubber pad to prevent the device from slipping in your hand. The internal part consists of a washer, a cotter pin that controls the mechanism, an axis for replacing the lever, a spring and two steel balls. The end of the handle has a flat shape; a sting is installed on a removable section of the tool. Modern types of screwdrivers are equipped with reverse. The kits contain long or simple 25 mm bits from 2 to 6 pcs.

Working principle of an impact screwdriver

A simple mechanical tool is easy to use. You need to find out how an impact screwdriver works, what the mechanism of action is. The use of the unit does not require special knowledge and skills. Anyone can use the device. The tool is installed at a right angle with a tip into the thread of a screw or bolt. Using a neat, precise movement, strike the outer base of the screwdriver with a hammer. Upon impact, the thread on the nut rotates 1-2 mm towards its axis. Apply several shock-turning movements to unscrew the stuck fastener.

Principle of operation

According to its principle, the operation of the tool is quite simple and there are no difficulties when using it. After hitting the end surface with a hammer, the element rotates on the bottom of the screwdriver. This rotating force is quite enough to dismantle strong fasteners.

To simplify the work process, you can pre-lubricate the fasteners with brake fluid. After this, you need to install the tool at a right angle to the head of the hardware and use a hammer to strike the end of the screwdriver. After noticeable rotation of the fasteners, you can continue unscrewing using a regular screwdriver.

Even a person with no experience can operate this type of tool. However, to make an impact screwdriver you need an idea of how it works and the availability of the appropriate parts from which it will be made.

What is an impact screwdriver used for?

Each technical tool has its own functional purpose. An impact rotary screwdriver is used to unscrew fasteners. Improved models with installed reverse not only remove screws, but also tighten self-tapping screws. The manual mechanism is used in metalwork and the automotive industry. The impact-rotary design is successfully used at home when repairing sanitary equipment. A steel impact screwdriver is effective for disassembling motor engines.

Advantages of a homemade tool

The screwdriver is equipped with a reinforced body made of high-strength steel.
It is larger in size compared to factory screwdrivers;
Operation of the tool is safe for humans when struck correctly with a hammer. If you follow the safety rules, it is impossible to get injured with a screwdriver;
There is the possibility of changing attachments, based on the type of work being carried out;
Easily made at home without significant physical and financial costs;
Multifunctionality. Can be used for various tasks in the field of construction, automotive, and any other craft.

How to choose an impact screwdriver?

Construction markets and hypermarkets offer a huge selection of tools of various profiles. If you don’t know which impact screwdriver to choose for daily professional use, then before purchasing you need to familiarize yourself with the options and brands offered by the manufacturers. Recommendations for selection:

Decide what purpose you need the screwdriver for. For daily use, purchase a tool with a powerful handle in a rubber casing.
Models with reverse perform two functions: mounting and dismantling the mount.
A set with a large number of different attachments is suitable for professional activities.

Impact screwdriver bits

Included with the tool, depending on the model and brand of the manufacturer, from 2 to 20 bits of different formats are offered. The impact rotary screwdriver is equipped with two types of attachments: Phillips and flat. The composition from which the nozzle is made is of great importance during operation. Nickel and chromium bits have increased strength and a long service life. Nozzles made from low-quality raw materials become deformed and break when used. The cost of hand tools depends on the material, number of bits, and manufacturer.

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.

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.

Each tool usually comes with instructions, and an impact screwdriver is no exception. But often such instructions are written in a foreign language. In this case, you can download the instructions for the impact screwdriver on the Internet, there are plenty of them here.

Impact screwdriver. Is it worth buying?

In this article, I want to disassemble such a tool as an impact screwdriver, tell you its principle of operation and give examples where it can be used.

One day, when I was repairing a Soviet motorcycle, I encountered a problem. The gearbox cover screws were tightly tightened. Due to the fact that the motorcycle has not been used for a long time, the screws have also rusted. Having difficulty unscrewing all the screws except one single one, I wondered how to unscrew it. Having suffered quite a bit, I erased the entire surface of the screw, which could somehow be grabbed with a screwdriver. As a result, I decided to buy an impact driver. I immediately ruled out the drilling method, since as a result of drilling there was a possibility of damage to the gearbox cover. Having bought a screwdriver, the first thing I decided to do was test it on that same “ill-fated” screw. To my surprise, the screwdriver did not require any special knowledge or difficulties in operation. I cocked it to the unscrewing position, put it on the screw, and hit it with a hammer from above. Noticing that the screw had moved out of place, I repeated this procedure several more times until the screw began to unscrew freely.

I told this story to show by example that a screwdriver really works.

The principle of operation is based on the fact that, having fixed it in the position of unscrewing or tightening (yes, yes, exactly that. A screwdriver works not only for unscrewing, it also allows you to tighten it quite strongly)

, we insert a screwdriver into the slot of the screw, then, instead of the usual rotation with our hands, we hit the screwdriver with a hammer. The screwdriver mechanism is designed in such a way that when struck, the handle goes down and the bit begins to rotate. The rotation is small, but it is enough to move the screw from its place. Another advantage is that the impact and rotation occur simultaneously, so it is not necessary to press the screwdriver, just hold it. Another plus is that the screwdriver comes with a set of fairly high-quality bits that can withstand fairly heavy loads. I would also like to add that the screwdriver has a 1/2 square seat, as a result of which you can easily use a screwdriver with 1/2 socket heads and unscrew bolts and nuts.

How to use an impact screwdriver?

When performing any repair or technical work, safety precautions must be observed. There are recommendations on how to properly use an impact screwdriver when loosening a screw. In order for the purchased tool to serve for a long time, you need to read the operating instructions and follow all the advice.

Prepare your tools: impact screwdriver, set of bits, hammer.
Wear gloves when working to prevent injury and contamination.
Check the new screwdriver for grease; if the mechanism is dry, lubricate it with MC1000 grease.
Insert the required bit size into the connecting part.
Clean the screw cap from dust and dirt.
Place the blade of the screwdriver into the screw thread perpendicularly, at a right angle.
Using a not very strong blow of the hammer, apply a pointed blow to the heel of the screwdriver.
Repeat several times so that the clip moves along its axis.
When the screw moves freely, unscrew the screw with a screwdriver.

Advantages and disadvantages of the tool

All tools have their advantages and disadvantages, and an impact driver is no exception to this rule. The advantages include:

the ability to unscrew rusty fasteners when a conventional screwdriver cannot do the job;
effective distribution of impact energy;
the ability to work alone without the involvement of a partner.

If we talk about the minuses, then there are practically none. True, during work you need to follow the rules to protect both yourself and the tool. Therefore, the disadvantages include:

Possibility of damage to the impact-rotating unit. The paradox here is that old monolithic structures have a longer service life than modern modernized solutions. To avoid damage, it is enough not to hit the impact-rotating mechanism too hard.
Tendency to wear out quickly. Gear teeth are subject to friction, which is accompanied by shock loads. With prolonged use, their resource begins to decline rapidly.

How to assemble a reversible screwdriver.

Dear Forum Gurus! Please give me a link or tell me how to assemble a reversible screwdriver. Thanks in advance!

Take the package. Put it all in there. Shake. If the screwdriver doesn't work, throw it all in the trash. Buy a new one. Well, you can also leave the handle for the moped.

Give it to the person who took it apart and let him put it back together.

if it’s not clear, follow the algorithm from the photos

Click on the slider and put the metal case on top. Watch the slot from the beginning. Then tighten it with a plastic nut. Good luck. I hope this is clear or does it need to be spelled out

a small horseshoe-shaped piece of iron is stuck from the BOTTOM into the slot - it secures the rod. Place two identical elements on both sides according to the photo. on top there is a slider with spring-loaded stops.

How to disassemble an impact screwdriver?

The simple device is not difficult to assemble and disassemble. The flat impact screwdriver is easily folded into parts and stored disassembled in a special case with a set of attachments. Algorithm for disassembling an impact screwdriver:

pull the bat out of the handle with a turning motion;
pry up the ring with a screwdriver or knife and carefully remove;
a movable device in the form of a V-shaped groove remains on the handle;
Inside the movable device there is a spring and balls that can be easily removed.

Video “Homemade impact screwdriver”

We remove unnecessary elements from the remaining part so that only the shaft and bushing remain, which we will use as the main mechanism.

We can use a small piece of pipe as a handle, into which we must place a sleeve on one side. On the other hand, we need to insert a plug, which will also serve as a striking heel. We use a large bolt as it; it will prevent the tube from deforming during impacts and will limit the displacement of the shaft inside our bushing.

The next step is welding all the parts.

Finally, the end of the shaft must be sharpened square for possible change of different attachments. So, to unscrew a screw or nut, it will be enough to insert the necessary bit and dismantle the fastener. If you need to unscrew a screw, you must insert the appropriate bit into the head.

It is worth noting that the electric starter is made of high-quality steel, so you will have to use a grinder to cut it. But thanks to its strength and carbide, the tool will be quite powerful and durable, and in some respects it will surpass even factory products. Periodic lubrication of the splines will help increase the service life of such a tool. However, you should use it carefully, without applying strong blows, so as not to tear off the heads of the screws or bolts.

Of course, the resulting product will be less presentable than a factory screwdriver, but its cost will be minimal and in terms of reliability it will be in no way inferior to its factory counterpart.

How to replace an impact screwdriver?

Is there an analogue that allows you to replace the tool? An impact Phillips screwdriver is considered a universal device for unscrewing and tightening old fasteners. The design of the device is convenient for use, does not require much effort, is compact, lightweight, and affordable. You can replace the screwdriver with an electric impact wrench, but this tool is not affordable for everyone and is only needed for a professional. An impact flat-head screwdriver cannot be replaced with a screwdriver, since the functional properties and principles of operation of the tools are different.

Useful tips

Quite often there is a need to unscrew heavily rusted fasteners. What to do in situations when a standard household tool cannot cope with the task? What to do in this situation, because household tools do not cope well with this task. A good solution for this is to use an impact screwdriver. Thanks to it, unscrewing rusted parts will not be difficult. It is enough to wet the fasteners with brake fluid so that when dismantling the part can be unscrewed as easily as possible.

However, in some situations this does not help. There is no need to panic. Try lubricating the bolt with brake fluid again and leaving it for a while. The liquid will corrode the stagnant texture and you can do everything without significant effort using a percussion tool.

What kind of screwdriver handles can there be?

Screwdrivers differ in the shape and structure of the handle. This affects ease of use, strength and ability to transmit a certain torque.

Handles by design

Structurally, there are three types of screwdriver handles. Let's look at how they differ and where they are applicable.

L-shaped. Due to its pistol shape it gives increased leverage. This allows you to apply increased force when screwing or unscrewing the fastener. Most often it is produced with an asterisk or hexagon spline and is called an L-shaped key.

T-shaped. Has even higher torque. It is convenient to rest your palm on the T-shaped part and requires less frequent interception. If the crossbar is long, then you can hold on to it with both hands, which is important for large hardware with a rod diameter of 8-10 mm.

A turning point. The design consists of a working part, a rod and a handle, where the latter contains a hinge. Thanks to the built-in element, the straight axis can be broken and left at any angle from 1 to 90 degrees. This regulates the length of the lever and the force of action. A screwdriver is useful for hard-to-reach places.

Shaped handles

The comfort of holding and the applied force on the equipment depend on the shape of the handle.

Round handle. It has low torque because it slips in the hand.

Hexagonal handle. The pen type is popular in the USA. Convenient for grasping and tightening with force. The edges do not allow the handle to rotate.

Triangular handle. The most optimal option from an ergonomic point of view. The clenched hand has exactly this shape inside, so good torque is possible and less stress on the user.
