Ingersoll Rand 285B-S6 D-Handle Air Impact Wrench combines a No. 5 spline drive with up to 1,475 ft-lbs (2,000 Nm) of maximum torque for demanding heavy fastening and removal work. Operating at a 5,000 RPM free speed, this spline-drive configuration provides the power and extended reach needed for compatible heavy vehicle and equipment service applications.
Built on the 285B platform, the 285B-S6 is designed around power, control, and durability. Its swept-back handle supports maneuverability when positioning the wrench, while the 285B family features a high-efficiency 6-vane motor and feather-touch trigger for controlled operation. The spline-drive model measures 20.1" (511 mm) long and weighs 27.8 lb (12.61 kg).
