The CAT 18V Brushless 3/4″ High-Torque Impact Wrench DX73B is an industrial-grade cordless power tool designed for heavy equipment maintenance, structural steel erection, and commercial automotive tasks. Powered by a high-efficiency brushless motor, this bare unit provides up to 1700 Nm of maximum fastening torque across three electronic speed stages, alongside a nut-busting 2100 Nm of breakaway torque for removing seized or heavily rusted bolts. Built around a 3/4″ (19 mm) friction ring anvil, the DX73B features a protective rubber gearbox cover, constant torque delivery throughout the battery discharge cycle, and an auto-stop reverse function to prevent loose fasteners from dropping off during disassembly.
