The M18 FUEL 1/2" Compact Impact Wrench with Pin Detent delivers maximum access in tight spaces, up to 339 Nm of nut-busting torque, and maximum workspace visibility. This battery-powered impact wrench measures only 124.5 mm in length, with a POWERSTATE Brushless Motor to provide the power to remove stubborn fasteners, even in confined spaces. The MILWAUKEE 1/2" Compact Impact Wrench with Pin Detent has tri-LEDs that surround the anvil to deliver the user brighter light with fewer shadows. 4-Mode DRIVE CONTROL offers enhanced 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 Mode applies no more than 27 Nm of torque for hand-tight fastening applications to prevent overtightening. Mode 4 also features Bolt Removal Mode, where the tool 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 -ION battery pack (not included) fits all M18 tools, delivering more work per charge and more work over the life of the pack.
