How does a impact screwdriver work?

Impact screwdriver today is a very popular tool not only in construction, but also for working at home. It will be simply indispensable in those situations when it will be necessary to unscrew a firmly “welded” screw. An ordinary screwdriver in this case cannot help you with anything, but a impact one is a completely different matter.

What is this tool

If you look visually, then there are very few similarities with the screwdriver we are used to. This model has a metal body, which makes it more durable and even allows it to withstand strong blows with a hammer.

A set of impact screwdrivers usually comes with two nozzles: flat and cross. The connecting part, where the nozzles are installed, has the shape of a square. In fact, it is very convenient for the reason that you can fasten the end heads into it, which will give you the opportunity to work with bolts, screws and screws without much effort. This is especially good for the category of people who are constantly engaged in repairing cars.

With the help of a impact screwdriver, you can not only unscrew the fasteners, but also install new ones in their place.It is worth noting that this tool twists the details "for centuries". Believe me, you will not be able then to unscrew the bolt with a conventional screwdriver.

Impact screwdriver principle: how it works

The principle of operation of the tool is not as complicated as it might seem at first glance. When the hammer strikes the butt, the lower part begins to rotate with such force, which is quite enough for the nozzle to cope with the strongest fasteners.

Short instructions:

  • In order to simplify a task a bit, you can grease the fasteners with a cloth previously moistened with brake fluid before starting work.
  • Next, take our screwdriver and install it perpendicular to the head of the hardware.
  • We take a hammer in our hands and hit the end part of the tool with all our might.

After the fastener begins to turn around its axis, make a few more blows with a hammer. This is necessary in order for the screwdriver to switch back to the “tightening” mode. As you can see, it is not so hard to figure out how to use the impact screwdriver.

Making a screwdriver do it yourself

Oddly enough, you can make this very useful tool at home without much effort. The main thing is to figure out how the impact screwdriver works, then the work will go much easier.

Getting Started:

  • Prepare a rotor taken from an electric motor (small). From it you need to cut everything in such a way that only the shaft and the sleeve remain.
  • We take the sleeve and select a piece of metal pipe that fits in size to put on it. This will be our grip.
  • On the reverse side, you will need to insert a nut that is larger in size. This will give strength to the handle and will not break when hit hard with a hammer.
  • All parts are welded with each other.
  • Sharpen the end of the shaft to make it square.

Our homemade tool is ready. You need to put in just a little effort, and believe that the impact driver will turn out just as good as any purchased model.
