The Ingersoll Rand 285B-6 is a new, heavy-duty 1-inch drive pneumatic impact wrench featuring a 6-inch extended anvil, designed for high-torque fastening applications in trucking, fleet maintenance, heavy equipment, and industrial assembly. The tool uses a twin-hammer impact mechanism and delivers up to 1,350 ft-lbs of maximum loosening torque at 90 PSI, with a free speed of 5,000 RPM. It requires a 3/4-inch NPT air inlet and an air hose supplying 90 PSI at approximately 35 SCFM for full-power operation. The extended anvil allows access to deep-set wheel studs, spring U-bolts, and axle hardware where a standard-length wrench cannot reach. This unit ships new-in-box with the 6-inch extended anvil and D-handle grip installed, as confirmed by the photos.
