Our M18 FUEL™ 1/2" Compact Impact Wrench w/ Pin Detent Kit is the most compact in its class, delivering our users more power, the most access in tight spaces at only 4.9" in length, and maximum workspace visibility. Our cordless impact wrench features a POWERSTATE™ Brushless motor that generates up to 250 ft-lbs of fastening and nut-busting torque, providing our users with the power required for installation and removal, even in confined spaces. Our 1/2" impact wrench has tri-LEDs that 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 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. Our REDLINK PLUS™ Intelligence electronics make these controls possible while ensuring maximum performance, protecting the tool against overloads, over-heating, and over-discharge. Our M18 REDLITHIUM™ XC5.0 Extended Capacity Resistant Battery Packs included provide increased protection against oils, greases, and solvents.
