Tube Bender 180 CT-364A-08 An air impact wrench is a socket wrench power tool driven by compressed air. The air impact wrench delivers a great deal torque, which is often needed to twist the nuts free. A valve controls how much torque is applied. The tool can be set to spin in either direction. An air impact wrench should not be used for fine tightening of wheel nuts. An air impact wrench should also used only be with specially hardened impact sockets, extensions, and joints. The sockets are special 6-point types which can stand the sudden force that the wrench generates.
