The MILWAUKEE® M18 FUEL™ 3/8 Compact Impact Wrench w/ Friction Ring is the most compact in its class, delivering you 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 4.8 in length with a POWERSTATE™ Brushless motor to provide the power to remove stubborn fasteners, even in confined spaces. The MILWAUKEE® 3/8 Compact Impact Wrench has tri-LEDs that surround the anvil to deliver you 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 included M18™ REDLITHIUM™ HIGH OUTPUT™ CP3.0 Battery Pack provides 50% more power and runs 50% cooler vs M18™ REDLITHIUM™ CP battery packs. This increased performance results in the same power and runtime of a M18™ REDLITHIUM™ XC battery in a lighter and more compact package. The 18-volt battery pack delivers fade-free power and runs substantially cooler through heavy applications, allowing trade professionals to push their cordless tools throughout a wide application range. The REDLITHIUM™ HIGH OUTPUT™ CP3.0 battery is fully compatible with all Milwaukee M18™ solutions.
