The Milwaukee 2966-20 is a cordless 1/2-inch impact wrench built on the M18 FUEL platform, with a POWERSTATE brushless motor rated at up to 900 ft-lbs of fastening torque and 1,100 ft-lbs of nut-busting torque. It is a high-torque tool aimed at mechanics and heavy equipment work, and it competes with corded-class impact wrenches from DeWalt, Makita and Ingersoll Rand. Its standout controls are a bolt removal mode that breaks a fastener free then drops to 750 RPM, and an AUTO-SHUTOFF mode that caps torque at 50 ft-lbs for small fasteners. Owners of the M18 line value the shared battery platform; the bare tool plus bonus XC5.0 Resistant battery kit means it arrives ready to run for anyone already on M18.

Owners of the M18 FUEL high-torque impact wrenches praise the torque and the bolt removal and AUTO-SHUTOFF modes for real shop work. Complaints center on weight and size and on the need for high-capacity batteries to get full power.
This kit pairs the Milwaukee M18 FUEL 1/2" pin impact wrench (2966-20) with an M18 REDLITHIUM XC5.0 Resistant battery. The wrench is supplied as a bare tool, and the battery is included in the kit.
A POWERSTATE brushless motor delivers up to 900 ft-lbs of fastening torque and 1,100 ft-lbs of nut-busting torque. A patented battery isolation system keeps the battery connection secure and controls the vibration transmitted to the pack. Three LEDs light the workspace with less shadow.
Bolt removal mode applies maximum nut-busting torque to break a fastener free, then slows to 750 RPM for more control during removal. Auto-shutoff control prevents over-tightening by applying no more than 50 ft-lbs of torque.
