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. Battery and charger sold separately.
