The Milwaukee M12 FUEL 3/8 in. Right Angle Impact Wrench w/Friction Ring is the industry's most powerful right angle impact wrench. This battery-powered right angle impact wrench delivers up to 220 ft. lbs. of nut-busting torque without kickback. This durable cordless impact wrench easily fits into tighter spaces than traditional pistol-grip impact wrenches with a profile head of only 2.2 in., reducing the user's need for socket extensions. The 4-Mode Drive Control provides users with unmatched control in various fastening and bolt removal applications. Modes 1-3 provide RPM and IPM adjustments for precision control. Mode 4 has Auto Shut-off in forward and Bolt Removal Mode in reverse. The Auto Shut-off Mode prevents over-tightening of bolts by applying no more than 15ft-lbs. of torque. Bolt Removal Mode drastically slows down the RPMs once the bolt is loosened for more control. Our M12 REDLITHIUM HIGH OUTPUT CP2.5 Battery Pack delivers 25% more power and runs 25% cooler vs our other M12 REDLITHIUM CP battery packs. This increased performance of the lithium-ion battery gives you the same power and runtime of an M12 REDLITHIUM XC battery in a lighter and more compact package. The 12-Volt battery pack delivers fade-free power and runs substantially cooler through demanding applications, allowing you to push your cordless power tools throughout a wide range of applications.
