The MILWAUKEE® M18 FUEL™ 1 High Torque Impact Wrench w/ ONE-KEY™ is the first cordless 1 in High Torque Impact Wrench. The POWERSTATE™ Brushless Motor delivers up to 1,800 ft-lbs of Nut-Busting Torque and 1,500 ft-lbs of fastening torque, making this the most powerful cordless impact torque wrench, able to complete the most demanding applications. At only 13 lbs with battery, the tool is up to 7 lbs. lighter than corded units, providing less fatigue for easier overhead job site applications. The battery-powered impact wrench has cordless convenience and eliminates the need for compressors, generators, cords, and hoses, reducing the cost of ownership. A lack of reliance on cord and hoses allow for greater portability and the ability to complete applications unable to be performed with a corded or pneumatic unit. The REDLINK PLUS™ Intelligence achieves maximum performance and protects the high torque impact gun against overloads, over-heating, and over-discharge. M18™ REDLITHIUM™ Battery Packs are compatible with all M18™ tools, delivering more work per charge and more work over the life of the pack. The 4-Mode DRIVE CONTROL™ provides greater control over the output speed and power of the high power impact wrench. The ONE-KEY™ capabilities allows for Customization, Tracking, and Management of the impact wrench. ONE-KEY™ technology also provides the ability to set a repeatable torque output for maximum control.
