Cordless Impact Wrenches


Loosen stuck fasteners and drive in fasteners with high force anywhere on your site. These impact wrenches run on a rechargeable battery, so you don’t need to be near an outlet to use them. Wrenches operate at full torque in the counterclockwise direction. The working torque range applies to the clockwise direction, often used for fastening. Use these wrenches with impact sockets only.
Some wrenches come with batteries and a charger. For others, batteries and chargers are sold separately.
Pin- and ring-and-hole-style socket retainers, also called positive-locking socket retainers, provide a more secure hold than ring-style retainers. Hole-style retainers require a retaining ring (included).
