Our M18 Fuel 1/2 in high torque impact wrench with friction ring 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-lb of fastening torque and 1,500 ft-lb of nut-busting torque when paired with our M18 Redlithium XC5.0 battery, while the compact size at 7.6 in L gives users greater access in tight spaces. 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-lb 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 rpm once the bolt is loosened to prevent fastener drops. The 1/2 in friction ring design allows for quick and tool-free socket changes. The M18 Redlithium XC5.0 resistant battery included provides increased protection against oils, greases, and solvents.
