Our 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. 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. Mode 4 also features Bolt Removal Control delivers full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops.
