Ingersoll Rand 2-Super-Duty Air Impact Wrench | 588A1 | 50,000 (ft-lbs) Torque | 2-1/2" Square Drive

When removing or tightening exceptionally large fasteners on mining machinery, steel mill equipment, and heavy industrial installations, the Ingersoll Rand 588A1 Super-Duty Air Impact Wrench delivers the torque capacity required for high-load bolting operations. Part of the 5000 Series, this pneumatic impact wrench produces up to 50,000 ft-lbs of maximum reverse torque for loosening highly resistant fasteners, with a 12,000–25,000 ft-lbs recommended working torque range for controlled selection of heavy fastening applications. Its 2-1/2" square drive features a thru-hole socket retainer for securing compatible large-format impact sockets. The T-handle configuration provides multiple gripping positions, while lever throttle actuation allows the operating team to control tool engagement during demanding bolting tasks.

Operating at 355 RPM free speed and delivering 550 impacts per minute, the 588A1 combines relatively low rotational speed with exceptionally high torque output for large threaded connections. Its precision ball and cam impact mechanism transfers repeated rotational impacts to the fastener, while the cast iron hammer case and bronze end-plate provide resistance to wear and corrosion in challenging environments. A built-in lubricator supports lubrication of internal components, and the multi-vane air motor provides smooth, consistent operation. With a 1" NPT air inlet and an air consumption rating of 155 CFM at load, this wrench requires a properly sized industrial compressed-air supply. At 215 lbs, the tool is intended for supported operation by a minimum of two people, as specified by Ingersoll Rand.
