An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft.

Fitted with rocking-dog hammer and hardened impact anvil. Suitable for general garage use. Features four-position adjustable air/torque control and reversible action.

Impact drivers features a drive (also referred as chuck or collet) that only accommodate 1/4" hex bits, which is great for when you need to fasten different types of screws. The drive on impact wrenches is different, they are called square drive. They come in three common sizes: 1/4”, 3/8”, and 1/2" square drives
