Power and Performance

The Northern Industrial Tools 1in. Air Impact Wrench has power to spare for all of your biggest, toughest jobs! The pinless hammer impact mechanism transfers power directly to the anvil for reduced vibration. The 1in. drive handles the largest jobs with ease. With 2,300 ft.-lbs. of working torque, even the tightest nuts will break loose.

Convenience Features

A rear D-handle and additional side handle make the Northern Industrial Tools 1in. Air Impact Wrench easy to handle. Forward/reverse settings and RPM control are conveniently placed near the primary handle. Air exhausts through the handle, keeping dust and debris away from your face as you work. Rubber bumper rings protect the tool from drops and impacts for longer service life. 38mm and 41mm sockets are also included to cover common sizes of axle nuts. A sturdy case keeps the wrench and accessories protected and ready for the next job.
