The MILWAUKEE M12 FUEL 1/2 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. Milwaukee REDLINK PLUS Intelligence ensures users achieve maximum performance and protection against overloads, over-heating, and over-discharge. The M12 REDLITHIUM Battery Packs (not included) are compatible with all M12 tools, delivering more work per charge and more work over the life of the pack.
