The M18 FUEL 1″ High Torque Impact Wrench with ONE-KEY is the world’s first cordless 1” 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 and enabling you to complete the most demanding applications. At only 13 lbs with battery, the tool is up to 7 lbs. lighter than corded units, providing you with less fatigue while making overhead applications easier to complete on the job site. The battery-powered impact wrench provides you with cordless convenience and eliminates your need for compressors, generators, cords, and hoses. This reduces your cost of ownership by lowering energy costs and eliminating routine maintenance on compressors and generators. With no cord or hoses, you have greater portability and the ability to complete applications you were not able to do with a corded or pneumatic unit. The REDLINK PLUS Intelligence ensures you achieve maximum performance and protects your high torque impact gun against overloads, over-heating, and over-discharge. M18 REDLITHIUM Battery Packs are compatible with all M18 tools, providing you with more work per charge and more work over the life of the pack. The 4-Mode DRIVE CONTROL provides you with greater control over the output speed and power of the high power impact wrench. The ONE-KEY capabilities provide you with the ability to Customize, Track and Manage the impact wrench. ONE-KEY technology also gives you the ability to set a repeatable torque output for maximum control.
