The M12 FUEL 1/2" Pin-Detaining Right Angle Impact Wrench is the industry's most powerful right angle impact wrench. With up to 220 ft-lbs. of nut-torque torque, removing tough bolts and fasteners is no longer a problem. Coupled with power, the tool offers users maximum access and ultimate control for hard to reach applications. With a head profile of only 2.8 inches, this tool easily fits into tight spaces making users more productive, while decreasing their need for socket extensions often used with pistol grip impact tools. The 4-mode drive control will allow for unmatched control in various screw fastening and removal applications. Modes 1-3 provide RPM and IPM settings for precision control. In mode 4, this tool is equipped with auto shut-off mode in forward and bolt removal mode in reverse. The Auto Shut-Off mode will prevent over-tightening of bolts by applying no more than 15 ft-lbs of torque. The Bolt Removal Mode will provide more control as the RPM slows dramatically once the bolt is loosened. REDLINK PLUS intelligence ensures users maximum performance and protects the tool from overloading, overheating, and over-discharging. M12 REDLITHIUM battery packs are compatible with all M12 tools, delivering more work per charge and more work over the life of the pack.
