Our M18 FUEL 1/2 in HTIW w/ Friction Ring & Grease Gun Combo Kit includes 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 1,500 ft-lbs of Nut-Busting Torque when paired with our M18 REDLITHIUM XC5.0 Battery, while the compact size at 7.6 in in length gives users greater access in tight spaces. The M18 FUEL 1/2 in High Torque Impact Wrench w/ Friction Ring maximizes productivity on the jobsite and in the shop by removing stubborn bolts and fasteners faster than cordless competitors. Our 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 our users full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops. The 1/2 in Friction Ring design allows for quick & tool-free socket changes. The M18 REDLITHIUM XC5.0 Resistant Battery included provides increased protection against oils, greases, & solvents.
