The Milwaukee M18 FUEL ½” High Torque Impact Wrench w/ Friction Ring is the most power-dense impact wrench in its class, provides greater access in tight spaces, and maximizes productivity through faster removal speeds. The POWERSTATE Brushless Motor delivers up to 1,100 ft-lbs. of Fastening Torque and 1,600 ft-lbs. of Nut-Busting Torque when paired with the M18 REDLITHIUM FORGE Batteries, while the compact size at 7.6 in. L gives users greater access in tight spaces. The patented battery isolation system provides a secure battery connection and controls vibration transmitted to the pack. Tri-LEDs surround the anvil to deliver brighter light with fewer shadows. 4-Mode DRIVE CONTROL offers greater precision with a range of pre-set RPM and IPM levels, selectable from a single button on the tool. By selecting Mode 4, AUTO SHUT-OFF control applies no more than 50 ft-lbs. of torque for hand-tight fastening applications to prevent overtightening. Mode 4 also features Bolt Removal Control that delivers users full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops. The ½” Friction Ring design allows for quick & tool-free socket changes.
