The Milwaukee 2867-22 M18 FUEL 1 inch High Torque Impact Wrench with ONE-KEY Kit is a cordless heavy-duty fastening tool built for high-torque bolting work. This is a 1 inch cordless impact wrench designed for loosening and tightening large fasteners in demanding service, construction, utility, and industrial applications. Model Number 2867-22. If you need big torque without hoses, compressors, or generators, this is the setup Milwaukee built for the job.

The main reason people buy this tool is simple: power. The POWERSTATE brushless motor delivers up to 1,800 ft-lbs of nut-busting torque and 1,500 ft-lbs of fastening torque, which puts this impact wrench in serious heavy-equipment territory. For seized lug nuts, structural bolts, flange work, and large anchors, those numbers are what let you break hardware loose and finish work faster without reaching for pneumatic gear.

Milwaukee also made a strong case for going cordless here. The tool weighs about 13 lbs with battery and is listed as up to 7 lbs lighter than comparable corded units. That matters on overhead work, roadside service, or anywhere you're carrying the tool up ladders, around equipment, or across a site. Losing the cords, hoses, compressor, and generator also means less setup, fewer trip hazards, and less gear to maintain.

Control is a big part of what separates a brute-force impact wrench from one that's actually useful across different tasks. This model uses 4-Mode DRIVE CONTROL, so you can match output speed and power to the fastener and the application instead of hitting everything at full force. ONE-KEY adds another layer by letting you customize settings, track and manage the tool, and set repeatable torque output. For fleet users and crews trying to keep tools accountable, that is not a gimmick. It solves a real jobsite problem.

From a hardware standpoint, the Milwaukee 2867-22 uses a 1 inch square anvil with a friction ring and thru-hole. That setup is meant for large sockets and heavy-duty fastening work where secure socket retention matters. Milwaukee also includes a tool-free adjustable handle that rotates 270 degrees, which helps you brace the tool in the position that makes the most sense for the workpiece and your body position. There is also an integrated lanyard loop for safer use and easier storage, plus an LED light for darker work areas.

Jobsite durability and electronics protection are just as important as peak torque on a tool like this. Milwaukee's REDLINK PLUS intelligence is built in to help the wrench maintain performance while protecting against overloads, overheating, and over-discharge. The rubber overmold is designed to hold up against corrosive materials and improve grip comfort, which matters when this tool is getting used in service trucks, plants, and rough site conditions instead of sitting on a shelf.

On the battery side, this kit runs on the Milwaukee M18 platform and includes two M18 REDLITHIUM FORGE XC8.0 battery packs plus an M18 and M12 Rapid Charger. The platform compatibility is a big advantage if you're already invested in M18 tools because the batteries work across the broader M18 system. For a high-draw cordless impact wrench, having two 8.0Ah packs in the kit makes this a lot more practical for full-shift use than a bare tool purchase.

Who is this for? Mechanics working on heavy trucks, utility crews, ironworkers, industrial maintenance techs, rail and plant maintenance, and contractors dealing with large structural or anchor bolts. If your work regularly calls for a 1 inch impact wrench and you want to ditch air lines without giving up serious output, this is the kind of tool that earns its keep fast. If your work is mostly automotive passenger vehicles or smaller hardware, it is more tool than you need.

Milwaukee 2867-22 is Built for Big Hardware

If you need a real 1 inch cordless impact wrench for heavy fasteners, the Milwaukee 2867-22 gets you air-tool kind of capability without dragging the air system around.

• Who it's for: Heavy equipment mechanics, utility crews, industrial maintenance teams, and contractors who deal with large bolts on a regular basis.
• Why it stands out: The combination of 1,800 ft-lbs of breakaway torque, lighter cordless form, 4-mode control, and ONE-KEY fleet features makes it more than just a big impact wrench.
