PROFACTOR 18V 3/4 In. Impact Wrench with Friction Ring and Thru-Hole (Bare Tool)

The Bosch GDS18V-770 18V PROFACTOR 3/4 In. Impact Wrench with Friction Ring and Thru-Hole is designed for breaking free and driving large bolts, nuts and anchors quickly. It is part of the PROFACTOR System, which pairs BITURBO Brushless Technology with a CORE18V PROFACTOR battery. BITURBO Brushless Technology is a high-performance motor and drive-train system designed to deliver power comparable to high-demand corded tools. The tool delivers up to 770 Ft.-Lbs. fastening torque and 1,250 Ft.-Lbs. breakaway torque, while maintaining long runtime. It offers controlled power output, with three speed/torque settings (0-800/1,200/1,750 RPM). The wrench features a rubber head casing that protects workpiece and tool from damage. This is a bare tool; battery and charger are sold separately.
