Conquer high-torque fastening tasks inside tight, crowded engine bays and structural frames with the Milwaukee® M18 FUEL™ 3/8" Compact Impact Wrench with Friction Ring. Engineered to provide the industry's best physical balance of raw power and subcompact sizing, this battery-powered impact tool utilizes a premium large-frame POWERSTATE™ brushless motor. It pushes a massive 250 ft-lbs of nut-busting breakaway torque to shatter loose rusted or stubborn fasteners, yet its ultra-short 4.8-inch chassis profile easily slips into confined pockets where standard impact guns cannot fit. To maximize user precision and protect sensitive work surfaces, the wrench comes integrated with a 4-Mode DRIVE CONTROL™ button interface. Mode 4 activates an intelligent dual-protocol system: during installation, the AUTO SHUT-OFF™ function caps structural tightening force at no more than 20 ft-lbs to eliminate over-torque or stripped threads. Conversely, during disassembly, Bolt Removal Control unleashes the motor's full 250 ft-lbs break-free potential, then drops the RPMs down the instant a fastener breaks free to keep nuts from spinning loose and dropping into deep machinery voids. A surrounding Tri-LED headlight array showers the target anvil in high-definition light to eliminate frustrating shadows. Built with high-tier component safeguards, the kit includes REDLINK PLUS™ Electronics to protect against over-discharges, a durable friction ring (hog ring) anvil for instant, tool-free socket swaps, and chemical-resistant battery pack housings optimized to withstand punishing garage oils and harsh solvents.
