What is an Air Impact Wrench Manufacturers' air wrench?
An air impact screwdriver is essentially a tool for tightening and unscrewing screws and bolts. They are so called because they are powered by compressed air: to work, they must be connected to an air compressor. Since this feature does not use electrical current, the pneumatic screwdriver is completely safe to use even in an environment that is not completely dry.

Structurally it is similar to a drill bit, although it is capable of performing some drilling operations, it differs from the latter in some special functions. In fact, screwdrivers are usually equipped with a speed reducer, called a blade, which reduces the number of revolutions of the tool. Typically, as with USAG impact wrenches, there may be two or more speeds: the lowest for tightening and the highest for loosening. You can also choose the direction of rotation, clockwise or counterclockwise, depending on whether you need to perform tightening or loosening.
