Overview

This is a cordless impact wrench designed for heavy-duty fastening in the shop and on the jobsite. The Milwaukee M18 FUEL 3/4″ High Torque Impact Wrench w/ ONE-KEY Kit (2964-22) delivers up to 2,000 ft-lbs of nut-busting torque and 1,800 ft-lbs of fastening torque, built to eliminate compressors and air hoses entirely rather than just supplement them.

A POWERSTATE Brushless Motor drives the wrench up to 40% faster than cordless and pneumatic competition, and it’s rated to install up to 120 1-1/4″ bolts on a single REDLITHIUM FORGE XC8.0Ah battery – real all-day capacity for structural steel, heavy equipment, or fleet work where you’re turning dozens of large fasteners in a shift. A patented Battery Isolation System controls pack vibration for a secure connection, which matters on a tool putting out this much impact energy – a loose battery connection under heavy recoil is a common failure point on lesser wrenches.

ONE-KEY adds 4-Mode Custom Drive Control: AUTO SHUT-OFF caps forward fastening torque at 75 ft-lbs to prevent over-torquing small fasteners, while Bolt Removal Mode in reverse runs at full RPM and impact rate until the nut breaks free, then automatically slows to 750 RPM for controlled removal instead of sending a loose nut flying.

This wrench uses a friction ring anvil rather than a pin detent, and it’s fully compatible with the entire M18 REDLITHIUM battery and charger lineup. It’s built for structural and heavy fastening work – steel erection, heavy equipment repair, and fleet maintenance – where the 3/4″ drive and 2,000 ft-lb ceiling matter more than compact size.

All-Day Power Without the Compressor

Up to 2,000 ft-lbs of nut-busting torque means this wrench replaces pneumatic tools outright instead of just filling in when the compressor isn’t running.

• Up to 2,000 ft-lbs nut-busting torque, 1,800 ft-lbs fastening torque
• Installs up to 120 1-1/4″ bolts per XC8.0Ah battery charge
• Patented Battery Isolation System for a secure connection under heavy impact

Two Modes That Prevent Fastener Damage

AUTO SHUT-OFF and Bolt Removal Mode take the guesswork out of both directions – fastening and removal – instead of relying on trigger control alone.

• AUTO SHUT-OFF: caps forward fastening torque at 75 ft-lbs
• Bolt Removal Mode: full power in reverse, then slows to 750 RPM for control
• ONE-KEY enabled for custom, repeatable drive settings

Pro Tip

Use Bolt Removal Mode any time you’re breaking loose a seized or rusted fastener in reverse – it runs at full power to break it free, then automatically drops to 750 RPM so the nut doesn’t go flying once it lets go.

Tool Nut’s Take

Tool Nut’s Take

Structural-Grade Torque Without the Compressor

The Milwaukee M18 FUEL 3/4″ High Torque Impact Wrench w/ ONE-KEY is built for the fastening jobs that used to require a pneumatic gun and a compressor trailer.

• Who it’s for: Steel erection crews, heavy equipment techs, and fleet maintenance shops running large fasteners all day.
• Why it stands out: ONE-KEY’s Bolt Removal Mode and AUTO SHUT-OFF solve two different fastening problems most impact wrenches ignore entirely.
• Worth knowing: This is the full kit – tool, battery, charger, and case. If you’re already running M18, the tool-only 2964-20 saves you from paying for gear you don’t need.

Common Questions

• How much torque does this impact wrench deliver? Up to 2,000 ft-lbs of nut-busting torque and 1,800 ft-lbs of fastening torque.
• What’s the difference between this and the Extended Anvil version (2969-22)? This wrench uses a standard-length friction ring anvil built for structural and heavy fastening work; the 2969-22 adds a 6″ extended anvil specifically for commercial tire service.
• What does Bolt Removal Mode do? In reverse, it runs at full RPM and impact rate until the nut breaks free, then automatically slows to 750 RPM for controlled removal.
