The only variable-speed impact wrench of its kind. Weighing just 6.5 pounds, the 7/16 inch hex quick-change impact wrench offers a unique combination of high torque, speed and control for heavy-duty drilling and bolting applications that require frequent accessory changes. The Milwaukee-built motor produces up to 315 ft-lbs of torque while the variable-speed switch provides maximum user control at 1,800 RPM. It features a 7/16 inch hex quick-change retention system for fast yet secure insertion and removal of auger bits and socket adaptors. This impact wrench’s mid-positioned handle with cushioned grip provides superior balance and user comfort. It features an all-metal front housing for greater durability on the jobsite, and comes with a bracket and ring to make it easy to hoist the tool with a rope or carry it on a belt.
