Our M18 FUEL 1/2 in high torque impact wrench and 3/8 in mid-torque impact wrench automotive combo kit includes our M18 FUEL 1/2 in high torque impact wrench with friction ring that 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 1100 ft-lb of fastening torque and 1500 ft-lb of nut busting torque when paired with our M18 REDLITHIUM XC5 resistant battery, while the compact size at 7.6 in L gives users greater access in tight spaces. The M18 FUEL 1/2 in high torque impact wrench with 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. Our M18 FUEL 3/8 in mid-torque impact wrench with friction ring delivers the excellent power to weight ratio, most access in tight spaces and faster removal speed. It provides 600 ft-lb of nut busting torque and only weighs 5 lb, making it extremely versatile, capable of performing a wide variety of applications, such as removing large bolts or lug nuts. Tri-LEDs surround the anvil on both tools to deliver brighter light with fewer shadows. The M18 REDLITHIUM XC5 resistant battery packs included provide increased protection against oils, greases and solvents.Most power dense – excellent combination of power and sizeUp to 2 in L shorter, 7.6 in L provides most access in tight spacesFastest removal speeds maximize productivity on the jobsite and in the shopPatented battery isolation system ensures a secure battery connection and controls vibration transmitted to the pack6 in L provides most access in tight spaces on the mid-torqueTri-LEDs deliver high definition lighting to increase workspace visibility with less shadowsFriction ring (hog ring) ensures quick and easy socket changesREDLINK PLUS Intelligence – ensures maximum performance and protects from overloads, heating and over discharge
