The ACDelco Li-ion 18V 1/2 Super-Torque Impact Wrench with Digital Clutch is an innovative super heavy-duty tool that uses 4-pole motor technology to deliver maximum break-away torque of 1,100 ft-lbs, maximum reverse torque of 780 ft-lbs, and maximum tightening torque of 500 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 impact settings, allowing you to operate torque limiting with your fingertips. This wrench also provides a variable speed control of 0-1,600 RPM and no load speed of 0-2,000 Impact per Minute (IPM) for faster speed applications. The compact size of this ergonomic design at just 9-3/4 inches long and 7.04 lbs., means easier control and reduced turning force, while the built-in super bright LED illuminates your working area. Our charger utilizes a patented Air-Forced technology which forces air through the battery to cool it while charging it, allowing for faster charging times. Package includes: two Li-ion 18V 3.0 Ah battery packs, one 30 minute intelligent charger, and carrying case.
