Maximize control and maneuverability in tight industrial environments with the Milwaukee® M18 FUEL™ 1/2" Compact Impact Wrench with Pin Detent Kit. Engineered to fit into deeply recessed spaces where traditional heavy-duty impact guns fail, this compact tool features a slim 4.9-inch profile. Despite its small footprint, its high-performance POWERSTATE™ brushless motor cranks out up to 250 ft-lbs of breakaway torque to effortlessly break loose stubborn or corroded fasteners. The specialized 1/2-inch pin detent anvil provides maximum socket retention, mechanically locking sockets in place so they cannot shake loose during repetitive or overhead applications. To deliver superior adaptability on the job, the wrench is integrated with a 4-Mode DRIVE CONTROL™ panel. Engaging Mode 4 activates an intelligent dual-system: during fastening, the AUTO SHUT-OFF™ function limits output to 20 ft-lbs to prevent dangerous overtightening and stripped threads. For disassembly, the Bolt Removal Control unleashes maximum breakaway power, then automatically cuts motor RPMs the moment the fastener loosens to prevent dropping hardware into machinery. A surrounding Tri-LED headlight array floods the workspace with bright light to eliminate distracting shadows. Backed by advanced REDLINK PLUS™ system electronics, the kit includes multi-voltage charging and specialized chemical-resistant REDLITHIUM™ battery packs designed to withstand typical shop oils and solvents.
