M18 FUEL 1/2 Compact Impact Wrench w/ Pin Detent Bare Tool The MILWAUKEE M18 FUEL 1/2" Compact Impact Wrench w/ Pin Detent is the most compact in its class, delivering more power, the most access in tight spaces at only 4.9" in length, and maximum workspace visibility. This cordless impact wrench features a POWERSTATE Brushless motor that generates up to 250 ft-lbs of fastening and nut-busting torque, providing the power required for installation and removal, even in confined spaces. This battery-powered 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 cordless power tools, delivering more work per charge and more work over the life of the pack.
