Milwaukee High Torque Impact Wrenches: 1/2, 3/4 and Mid-Torque

Best for
Buyers wanting a ready-to-run kit

Best for
Home garages needing solid 1/2-inch power

The Milwaukee Electric 2666-20 is the M18 brushless high-torque wrench below the Fuel line. It lists up to 800 ft-lbs of fastening torque and 1,200 ft-lbs of nut-busting torque, with a variable speed trigger running 0 to 1,750 RPM and 0 to 2,000 IPM. REDLINK Intelligence links tool, battery and charger for overload protection, and a 1/2-inch friction ring anvil allows one-handed socket changes.

It weighs 5.9 pounds per the listing, the lightest figure among the Milwaukee high-torque tools here. The listing does not specify whether a battery is included, though the -20 suffix and single-item package suggest a bare tool. This wrench suits a home garage builder who wants real breaker-bar relief without paying for peak Fuel numbers. If you regularly fight rusted suspension bolts, the 2767-20 gives more headroom.

• 800 ft-lbs fastening, 1,200 ft-lbs nut-busting
• 0 to 1,750 RPM, 0 to 2,000 IPM
• REDLINK Intelligence
• Brushless motor, friction ring anvil

Best for
Automotive work with frequent socket swaps

The Milwaukee 2767-20 M18 Fuel High Torque is the 1/2-inch Fuel model with a POWERSTATE brushless motor delivering 1,000 ft-lbs of fastening torque and 1,400 ft-lbs of nut-busting torque. REDLINK PLUS electronics guard against overloading and overheating, and the friction ring anvil keeps socket swaps quick. It works with all M18 batteries, but none is included.

The listing gives a 9.65-inch length and 6-pound weight. The description is brief, so it does not specify speed settings or RPM figures. This tool suits the enthusiast doing automotive, construction or heavy equipment work on 1/2-inch sockets who already owns M18 packs. For more detail on this drive size, see our guide to the Milwaukee half inch impact lineup.

The Milwaukee Electric 2967-21B is a kit version of the M18 Fuel 1/2-inch high-torque impact wrench with friction ring, and it includes one 5.0 Ah battery and a bag. That makes it the only Milwaukee listing here you can use straight out of the box without owning M18 batteries.

The spec sheet lists 1,500 ft-lbs of torque, an 18-volt platform and a 7.6-inch length. The listed 11.2-pound weight likely reflects the kit, not the bare tool, and the listing does not break down fastening versus nut-busting torque, speed modes or electronics. The listing also does not specify whether a charger is included, so check before you buy. This kit suits a first-time M18 buyer who wants high-torque capability in one purchase.

Best for
Heavy trucks and 3/4-inch sockets

The Milwaukee 2864-20 Fuel One-Key 3 4″ High Torque Impact moves to a 3/4-inch anvil for truck, farm and heavy equipment work. Its POWERSTATE brushless motor delivers up to 1,200 ft-lbs of fastening torque and 1,500 ft-lbs of nut-busting torque, and REDLINK PLUS protects tool and battery from overload and overheating.

Milwaukee calls it the most compact cordless high-torque impact wrench in its class at 8.59 inches long, and it weighs 6.9 pounds. One-Key compatibility lets you customize, track and manage the tool’s performance and location through the app, and Milwaukee describes it as the most repeatable impact wrench in the industry. It is sold bare. This tool suits anyone running 3/4-inch sockets who wants the top of the range. For a deeper look, see our Milwaukee 3/4 impact high torque guide.

• 3/4-inch drive
• 1,200 ft-lbs fastening, 1,500 ft-lbs nut-busting
• One-Key customization and tracking
• 8.59-inch length, 6.9 pounds

Best for
Budget-minded M18 battery owners

The DIYtoolifz Cordless Impact Wrench 1 2 inch is not a Milwaukee tool. It is a third-party wrench built to run on Milwaukee M18 batteries, with the listing naming packs such as the 48-11-1850 and recommending 4 Ah or larger. It is sold bare.

The seller claims 1,350 ft-lbs of tightening torque and 1,700 ft-lbs of loosening torque, 3 forward speeds plus reverse with auto-stop, 0 to 1,850 RPM, a brushless motor, an ergonomic non-slip handle and an LED light. Reverse auto-stop halts the tool once a bolt breaks loose, which protects threads. These torque figures come from the seller and are higher than Milwaukee’s own ratings; you should treat them as claims, since the listing does not reference a test standard. It also lacks Milwaukee electronics such as REDLINK or One-Key. It suits a budget buyer who already owns M18 packs and wants an occasional heavy-duty tool.

Best for
Lug nuts and hand-tight control work

The Milwaukee 2962-20 M18 18V Fuel 1/2-inch Mid-Torque Impact Wrench is the Gen-2 mid-torque tool, sold bare with a friction ring. Instead of chasing peak numbers, it focuses on control. Auto shut-off applies no more than 35 ft-lbs for hand-tight fastening to prevent overtightening, and bolt removal control delivers full torque and then drops RPM once a bolt loosens so it does not fall.

Tri-LEDs light the work area with fewer shadows. The listing’s torque field shows 35 ft-lbs, which is the auto shut-off limit, and the listing does not specify maximum torque. This tool suits wheel work, suspension jobs and anyone who values a lighter, more controllable wrench over raw power. For bigger fasteners, step up to a high-torque model.

• Auto shut-off at 35 ft-lbs
• Bolt removal control
• Tri-LED lighting
• Friction ring anvil
