Built for vehicle service and general maintenance applications, the Chicago Pneumatic CP7729-P Pin Style Impact Wrench combines a 3/8" square drive with a 9,400 RPM free speed and 415 ft-lbs maximum reverse torque. Its twin hammer impact mechanism delivers the impact action specified in the Chicago Pneumatic General Industry catalog, while the pin-style retainer helps secure compatible impact sockets during fastening and removal work.
The CP7729-P provides a 50–300 ft-lbs forward working torque range, making the tool suitable for controlled tightening as well as fastener removal within its specified capacity. A 1/4" air inlet, 20 CFM air consumption at load, and 3/8" hose requirement complete the pneumatic configuration listed by the manufacturer.
