The MILWAUKEE M18 FUEL 1/2 Compact Impact Wrench w/ Friction Ring Kit 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. This battery-powered impact wrench measures only 4.9 in length with a POWERSTATE Brushless motor to provide the power to remove stubborn fasteners, even in confined spaces. The Milwaukee 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 that 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 cordless tools, delivering more work per charge and more work over the life of the pack. This kit includes (1) M18 FUEL 1/2 Compact Impact Wrench w/ Friction Ring, (2) M18 5.0Ah Batteries, (1) M12/M18 Charger, and a Carrying Case
