Impact Wrenches

An air impact wrench runs down and breaks loose fasteners that no hand tool will move, hammering the anvil instead of loading the operator’s wrist. Chicago Pneumatic keeps two separate families here. The industrial side handles plant, mine, and structural bolting: the 1 in./#5 spline CP0611, the 1-1/2 in. CP6135, and oil-bath twin-hammer tools like the CP6500. The vehicle-service side is built for tire bays, fleets, and general repair — the classic 1/2 in. CP734H and the 1,920 ft-lb CP7782 series. Drives run 3/8 to 1-1/2 in. square plus #5 spline and 7/16 in. hex, all at 90 psi maximum working pressure. Match impact sockets and adapters to the drive, compare the range on the CP air impact wrenches page, or step down to air ratchets for confined work.
