Built for fleet maintenance, heavy equipment service, truck repair, and industrial MRO operations, the Ingersoll Rand 2155QiMAX Air Impact Wrench delivers up to 1,350 ft-lbs of maximum reverse torque for removing stubborn fasteners while operating at a 7,000 RPM free speed to speed up run-down and installation. Its 1-inch square drive is compatible with heavy-duty impact sockets, making it well suited for demanding bolting applications where consistent power and reliability are essential.
The 2155QiMAX is part of Ingersoll Rand's QiMAX Series and features a twin-hammer impact mechanism (delivering two powerful hammer strikes per rotation for balanced torque output and long-term durability). A titanium hammer case and composite motor housing help reduce tool weight while maintaining durability, and the quiet technology package lowers operating noise without sacrificing performance, making it suitable for extended use in busy maintenance environments.
