Ingersoll Rand 285B D-Handle Air Impact Wrench is designed for heavy-duty vehicle service and equipment work where large fasteners demand substantial pneumatic torque. Equipped with a 1" square drive, the 285B delivers up to 1,475 ft-lbs (2,000 Nm) of maximum torque and operates at a 5,000 RPM free speed, providing the output required for demanding fastening and fastener-removal jobs.
Its D-handle configuration and auxiliary side handle give the operator additional control when managing the tool's high torque output. The 285B uses a rocking-dog impact mechanism engineered for reliable power delivery, while the power regulator and convenient reverse control help operators adjust the wrench for changing service tasks.
