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.

Is this too powerful for my needs?

Yes if you're doing standard automotive work. This tool is built for heavy-duty trucks, seized fasteners, and industrial applications—anything lighter is overkill.

Will this replace my pneumatic impact?

In most cases, yes. It delivers comparable or higher torque without compressors, hoses, or air limitations, making it more efficient on-site.

Is the weight a problem for daily use?I

t’s heavy (~25 lbs with battery). That’s the cost of this level of torque. The D-handle design is specifically made to improve control and reduce strain.

Will it snap bolts or over-tighten?

It can if misused. Use DRIVE CONTROL modes or ONE-KEY torque settings to manage output and prevent over-torqueing.
