DIY impact screwdriver

An impact driver is a very useful tool for car repair. The device of this tool allows you to unscrew the "sour" and rusted bolts with a hammer. When striking inside the case, the front part is shifted where the desired bit is installed, as a result of which two efforts are combined that cope with difficult bolts.

You can make a shock device yourself, for this you will need tubes of different diameters and electric welding.
