Dominate heavy-duty vehicle repair, industrial assembly, and structural fleet maintenance with the Milwaukee® M18 FUEL™ 1/2" High Torque Impact Wrench and Grease Gun Combo Kit. Engineered for professional mechanics, agricultural technicians, and heavy equipment operators, the included 1/2-inch impact wrench delivers the industry's best combination of raw mechanical output and subcompact sizing. Driven by an advanced large-frame POWERSTATE™ brushless motor, it punches out up to 1,500 ft-lbs of nut-busting breakaway torque to effortlessly break loose rusted, stubborn chassis bolts while remaining up to 2 inches shorter than competing models at just 7.6" long. To prevent hand fatigue and protect expensive hardware, the wrench utilizes a 4-Mode DRIVE CONTROL™ system to quickly adjust performance parameters. Mode 4 engages an active AUTO SHUT-OFF™ protocol that caps installation force at 50 ft-lbs for quick hand-tight snugging, paired with a smart Bolt Removal Control that slows rotation down to 750 RPM the moment a bolt breaks free to keep hardware from flying loose. A patented physical battery isolation system absorbs incoming jobsite shock, mechanically protecting internal battery cells from extreme structural vibration. This industrial-grade package includes shadow-free Tri-LED headlights surrounding the anvil, a heavy-duty friction ring for rapid socket adjustments, and REDLITHIUM™ resistant batteries specially engineered to withstand degrading workshop greases, oils, and chemical solvents.
