The M18 FUEL 3/8" Compact Impact Wrench w/ Friction Ring is the most compact in its class, delivering our users the most access in tight spaces, up to 250 ft-lbs of nut-busting torque, and maximum workspace visibility. Our battery-powered impact wrench measures only 4.8" in length with a POWERSTATE Brushless motor to provide the power to remove stubborn fasteners, even in confined spaces. Our 3/8" Compact Impact Wrench has tri-LEDs that surround the anvil to deliver our users 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 20 ft-lbs of torque for hand-tight fastening applications to prevent overtightening. Our M18 REDLITHIUM XC5.0 Extended Capacity Resistant Battery Packs included provide increased protection against oils, greases, and solvents.
