The M12 FUEL 3/8 Right Angle Impact Wrench w/ Friction Ring is the industry's most powerful right angle impact wrench. With up to 220 ft-lbs. of nut-busting torque, removing stubborn bolts and fasteners are no longer an issue. Along with power, the tool offers users maximum access and ultimate control for hard to reach applications. With a head profile of only 2.8, this tool easily fits into tight spaces making users more productive while decreases their need for socket extensions often used with pistol-grip impact tools. 4-Mode Drive Control will allow unmatched control in various fastening and bolt removal applications. Modes 1-3 provide RPM and IPM adjustments for precision control. In Mode 4, this tool is equipped with Auto Shut-off Mode in forward and Bolt Removal Mode in reverse. Auto Shut-off Mode will prevent over-tightening of bolts by applying no more than 15ft-lbs. of torque. Bolt removal mode delivers more control as RPMs drastically slow down once the bolt is loosened. The REDLINK PLUS Intelligence ensures users achieve maximum performance and protects the tool against overloads, over-heating, and over-discharge. The M12 REDLITHIUM Battery Packs are compatible with all M12 tools, delivering more work per charge and more work over the life of the pack.
