Our M18 FUEL™ 1" D-Handle High Torque Impact Wrench w/ ONE-KEY™ Kit is the world’s first cordless 1” D-Handle High Torque Impact Wrench. The POWERSTATE™ Brushless Motor delivers up to 2,000 ft-lbs of nut-busting torque and 1,900 ft-lbs of fastening torque, making this the world's most powerful cordless impact wrench, enabling you to complete the most demanding applications. With the runtime to install up to 200 1-1/4" bolts on a single HIGH OUTPUT™ HD12.0Ah battery, this portable impact gun provides unmatched performance. The battery-powered impact wrench provides you with cordless convenience and eliminates the need for compressors, generators, cords, and hoses. With no compressor or hose, you have greater productivity and portability to complete applications not accessible with a pneumatic unit. This reduces your cost of ownership by lowering energy costs and eliminating routine maintenance on compressors and generators. The REDLINK PLUS™ Intelligence ensures you achieve maximum performance and protects the High Torque Impact Wrench against overloads, over-heating, and over-discharge. M18™ REDLITHIUM™ Battery Packs are compatible with all M18™ tools, providing this high torque cordless impact wrench with more work per charge and more work over the life of the pack. A patented battery isolation system manages high frequency vibrations, enabling battery movement that prevents damage and ensures a constant connection between the battery and tool when in use. The 4-Mode DRIVE CONTROL™ provides you with greater control over the output speed and power of the MILWAUKEE® High Torque Impact Wrench. The ONE-KEY™ Technology allows you to customize, track, and manage the impact wrench with the ability to set a repeatable torque output for maximum control.
