The MILWAUKEE® M18 FUEL™ 3/8 Compact Impact Wrench w/ Friction Ring is the most compact in its class, delivering the most access in tight spaces, up to 250 ft-lbs of nut-busting torque, and maximum workspace visibility. The Milwaukee cordless 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. The Milwaukee 3/8 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. REDLINK PLUS™ Intelligence electronics make these controls possible while ensuring maximum performance, protecting the tool against overloads, over-heating, and over-discharge. The M18™ REDLITHIUM™ battery pack (not included) fits M18™ tools, delivering more work per charge and more work over the life of the pack.
