The MILWAUKEE M18 FUEL 1 in. D-Handle Extended Anvil High Torque Impact Wrench w/ ONE-KEY is the world's first cordless 1 in. 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 users to complete the most demanding applications. With the runtime to remove and install up to 120 lug nuts on a single HIGH OUTPUT HD12.0Ah battery, the tool provides unmatched performance. Lug Nut Mode, which can be enabled through the ONE-KEY app, prevents the over-torque of lug nuts by automatically shutting off the tool, providing more control. The REDLINK PLUS Intelligence ensures users achieve maximum performance and protects the 6 in. extended anvil impact wrench against overloads, over-heating, and over-discharge. 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 users with greater control over the output speed and power of the High Torque Impact Wrench. The ONE-KEY Technology allows the user to customize, track, and manage the impact wrench with the ability to set a repeatable torque output for maximum control.
