Our M18 FUEL� 1/2" Mid-Torque Impact Wrench w/ Friction Ring delivers the best power to weight ratio, most access in tight spaces, and faster removal speed. It provides 650 ft-lbs of nut-busting torque and only weighs 5.1 lbs, making it extremely versatile, capable of performing a wide variety of applications. Its POWERSTATE� Brushless Motor generates the power needed to quickly perform many tasks, such as removing large bolts or lug nuts. This MILWAUKEE� 1/2" Impact Wrench is the most compact in its class, giving you access to stubborn fasteners in spaces where larger impact wrenches can�t fit without needing to disassemble components to reach bolts. Tri-LEDs 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 35 ft-lbs of torque for hand-tight fastening applications to prevent overtightening. Mode 4 also features Bolt Removal Control that delivers you full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops. REDLINK PLUS� Intelligence ensures 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.
