The ACDelco Li-ion 18V 3/8 Impact Wrench with Digital Clutch is an innovative tool that uses a 4-pole high-torque motor to deliver maximum breakaway torque of 170 ft-lbs, maximum reverse torque of 125 ft-lbs, and maximum tightening torque of 80 ft-lbs. It also features variable speed with reversible control and electric brake switch, along with our patent-pending ETC innovation (Electronic Torque Clutch) that provides six digital torque settings, allowing you to operate torque limiting with your fingertips. This wrench also provides a variable speed control of 0-2,000 RPM and no load speed of 0-3,000 Impact per Minute (IPM) for faster speed applications. The class-leading compact size of this ergonomic design at just 6-3/4 inches long and 3.63 lbs., means easier control and reduced turning force. The durable aluminum gearbox housing includes a 3/8 friction ring and built-in bright LED light to illuminate your working area. Finally, the LCD display shows torque stage, battery indication and torque stage memory functions. Package includes: two Li-ion 18V 2.0 Ah battery packs, one intelligent charger, and carrying case.
