The Milwaukee M12 Fuel 1/2" Right Angle Impact Wrench is the industry's most powerful tool of its kind. Stubborn bolts and fasteners are no problem for the wrench's up to 220 ft.-lbs. of nut-busting torque without kickback. This cordless right angle impact wrench also gives you maximum access with ultimate control in hard to reach applications. It easily fits into tighter spaces than traditional pistol-grip impact wrenches with a profile head of only 2.2". This allows you to be more productive by decreasing your need for socket extensions often used with pistol-grip impact tools. The Auto Shut-off Mode feature prevents over-tightening of bolts by applying no more than 15 ft.-lbs. of torque. Compatible with Milwaukee M12 RedLithium Battery Packs (sold separately).
