The 2967-21B is Milwaukee's cordless 1/2-inch high torque impact wrench, rated at 1,100 ft-lbs fastening and 1,500 ft-lbs nut-busting torque. It runs on the M18 battery system and comes as a kit with one XC5.0 battery, a multi-voltage charger and a contractor bag. At 7.6 inches long it is shorter than most high-torque cordless wrenches, which helps around suspension and frame work. It suits mechanics and tradespeople who want air-tool power without a compressor; it is heavy at 7.5 lb, so lighter mid-torque wrenches are easier for overhead work.

Key Features
Serious Breakaway Power
With up to 1,100 ft-lbs of fastening torque and 1,500 ft-lbs of nut-busting torque, this impact wrench is built to handle stubborn lug nuts, structural fasteners, and rusted hardware without dragging out an air hose.
Compact for the Class
At 7.6 inches long, the Milwaukee 2967-21B high torque impact wrench gives you better access around suspension parts, equipment frames, and other tight spots where larger high-torque tools get awkward fast.
More Control, Less Guessing
Four drive modes, Auto Shut-Off, and Bolt Removal Mode help you match output to the job. That means less overtightening on assembly work and better control once a fastener breaks loose.
Overview
The Milwaukee 2967-21B M18 FUEL 1/2" High Torque Impact Wrench w/ Friction Ring 5.0Ah Kit is a cordless high torque impact wrench kit built for mechanics, equipment techs, steel crews, and anyone who deals with large, stuck, or over-tightened fasteners. This is a high torque impact wrench designed for heavy-duty fastening and fastener removal. Model 2967-21B includes the tool, one M18 REDLITHIUM XC5.0 Resistant battery, an M18 and M12 multi-voltage charger, and a contractor bag, so you are not starting from scratch.
What matters most here is the output. Milwaukee rates this tool at up to 1,100 ft-lbs of fastening torque and 1,500 ft-lbs of nut-busting torque when used with the included XC5.0 battery. In plain terms, that puts it in the range for truck lug nuts, corroded suspension hardware, anchors, and large structural bolts where smaller mid-torque tools start to stall out. If your work regularly jumps from installation to teardown, this kind of reserve power saves time and a lot of frustration.
The other big story is size. Milwaukee calls this one of the most power-dense options in its class, and the 7.6 inch overall length is a practical reason why. A high torque impact wrench is usually the tool you grab when the job gets ugly, but that also means you are often working in wheel wells, inside machinery, or around pipe, brackets, and frames. A shorter body gives you a better chance of getting square on the fastener without switching to hand tools or tearing more apart than you want to.
The friction ring anvil is the right setup for users who swap sockets constantly. You get fast, tool-free socket changes without messing with a retaining pin every time you move from one size to another. For tire work, maintenance, fleet service, and general repair, that matters more than it sounds on paper. It is one of those small details that speeds up the whole job over the course of a day.
Milwaukee also gave this tool real electronic control instead of just raw output. The 4-Mode DRIVE CONTROL system lets you choose different speed and impact settings depending on the task. Mode 4 adds Auto Shut-Off control for hand-tight applications by applying no more than 50 ft-lbs of torque, which helps when you want to seat hardware without running it down too hard. Bolt Removal Mode gives full breakaway power to loosen the fastener, then slows to 750 RPM after it breaks free so it does not launch off the stud or drop out of your hand. That is the kind of feature that makes a powerful impact wrench easier to live with on daily work.
On the jobsite and in the shop, visibility and durability matter too. Tri-LED work lights surround the anvil area to light up the socket and fastener with fewer shadows, which is especially useful under vehicles and around dark equipment. Milwaukee also calls out a battery isolation system that helps keep the battery connection secure while controlling vibration transmitted to the pack. Paired with the included resistant battery that is built for added protection against oils, greases, and solvents, this kit makes sense for automotive bays, heavy equipment service, and industrial maintenance environments where tools do not stay clean for long.
Platform matters if you already own cordless Milwaukee tools. This kit runs on the M18 battery system and is compatible with all M18 batteries and chargers . That gives existing M18 users an easy way to add a top-end cordless fastening tool without buying into another platform. If you already have higher-capacity M18 packs, you can also tailor runtime and balance around the kind of work you do most.
Who should buy it? If you are regularly removing rusted fasteners, tightening large hardware, servicing vehicles, or working on steel and mechanical assemblies, this kit makes a lot of sense. It is also a smart step up for users who have outgrown a compact or mid-torque impact wrench and need more breakaway power without giving up cordless convenience. If your work is mostly small fasteners and light assembly, this is more tool than you need. But if you want one cordless impact wrench that can cove
