The Milwaukee Tool M12 FUEL Subcompact Impact Wrenches and Protective Boot are available in 1/4" and 3/8". These wrenches are designed to solve common size, weight, and productivity frustrations. These solutions deliver underhood access, up to 100 ft-lbs and 225 ft-lbs of nut busting torque, and are the lightest weight in their class, according to Milwaukee. A 4-Mode DRIVE CONTROL system offers precision and adaptability, including auto shut-off mode that limits torque for hand-tight applications and a bolt removal mode that slows RPM to prevent fastener drops. The available protective boot is form-fitting and lightweight to protect the tools and work surface while adding minimal size or weight.
