The Milwaukee M18 FUEL 2967-21B is a 1/2-inch high-torque impact wrench kit built around one big promise: up to 1,100 ft-lbs of fastening torque and 1,500 ft-lbs of nut-busting torque in a tool that is only 7.6 inches long. That is a lot of claimed power in a fairly compact body, and it puts the 2967 in direct competition with DeWalt’s DCF900B. This review covers what the kit includes, which torque figure actually applies to it, how the four drive modes work, what we could and couldn’t verify, and who should buy it.
Quick Verdict
Buy the 2967-21B if you already own Milwaukee M18 batteries or are building an M18 collection, and you regularly work on trucks, equipment, or seized hardware where a mid-torque wrench runs out of breakaway torque. Skip it if you mostly work on passenger cars and value a lighter tool, since a mid-torque wrench handles most of that work more comfortably.
What you get: the 2967-20 wrench, one M18 REDLITHIUM XC5.0 Resistant battery, an M18 and M12 multi-voltage charger, and a contractor bag.

The Milwaukee M18 FUEL 2967-21B Kit
The 2967-21B is the ready-to-use way to buy this wrench. The tool itself is the 2967-20, and the kit adds one M18 REDLITHIUM XC5.0 Resistant battery (built with a housing designed to resist oils, greases, and solvents), a charger that handles both M18 and M12 batteries, and a contractor bag. If you already own M18 batteries and a charger, the bare 2967-20 may make more sense, so compare the two before you buy.
Not the right fit if: you already own M18 batteries and a charger, or you don’t want to commit to the Milwaukee platform. A kit only makes sense if you need the battery and charger, and it is a bad fit if you work exclusively on light passenger-car jobs where a lighter mid-torque wrench does the same work.
| Pros | Cons |
|---|---|
| Very high claimed torque (1,100 / 1,500 ft-lbs with the included battery) Compact for a high-torque wrench at 7.6 in, with a Pro Tool Reviews weight of 5.9 lbs bare Mode 4 limits forward torque to 50 ft-lbs and adds bolt removal control in reverse Patented battery isolation system helps control vibration reaching the pack Tri-LED light and REDLINK PLUS overload protection Ready to use, with battery, charger, and bag included |
7.5 lbs with the battery attached is still a heavy tool to hold all day The higher 1,200 / 1,600 ft-lbs headline figure needs a FORGE battery you buy separately More power than most passenger-car work requires Torque numbers are manufacturer claims, and we found no independent measured figure for this exact model Only one battery in the kit, so heavy use may call for a spare |

Which Torque Number Applies to the Kit?
This is worth understanding before you compare specs across brands. Milwaukee’s headline figures depend on the battery. With the XC5.0 battery that comes in the 2967-21B kit, Milwaukee rates the wrench at up to 1,100 ft-lbs fastening and 1,500 ft-lbs nut-busting. The bigger 1,200 / 1,600 ft-lbs numbers seen on some retailer listings apply when the wrench is paired with an M18 REDLITHIUM FORGE battery, and Pro Tool Reviews saw exactly that 100 ft-lb bump on both figures when they tested the tool with a FORGE 6.0Ah pack. One owner on a retailer review page made the same point in plain terms, saying the higher advertised number relied on a special battery and the tool fell a little short with a regular pack. So if you compare the 2967 against another brand, use the 1,100 / 1,500 figure for the kit as sold, not the FORGE number.
The Four Drive Modes Explained
The 2967 has a 4-mode DRIVE CONTROL selected from a single button on the tool. According to Pro Tool Reviews, the first three modes are simply speed and power steps, and Mode 4 does double duty:
- Forward, Mode 4 (auto shut-off): the tool backs its speed down to about 900 RPM and applies no more than 50 ft-lbs of torque. Milwaukee describes this as a hand-tight setting meant to prevent overtightening.
- Reverse, Mode 4 (bolt removal control): the tool delivers full torque to break a fastener free, then reduces its speed once the bolt loosens, so the fastener doesn’t drop.
Even the 50 ft-lb ceiling in forward Mode 4 is below the roughly 80 to 120 ft-lb range commonly cited for passenger-car wheel torque, so this mode won’t tighten a wheel to spec. It is for running fasteners down, not for final torque.
Size and Weight
Pro Tool Reviews lists the 2967 at 7.6 inches long, nearly an inch shorter than its predecessor, and at 5.9 lbs as a bare tool or 7.5 lbs with the kitted 5.0Ah battery. Milwaukee markets it as compact, and it is compact for a high-torque wrench, but it isn’t small. A reviewer at The Drive made the same point in a 2024 hands-on, saying the head is smaller than other high-torque wrenches he owns, while noting the tool itself is not small. A retailer review from an owner also called it very heavy. That combination of high claimed torque and moderate size is the real appeal, but be realistic: at 7.5 lbs with a battery on it, this is a tool you use in bursts, not one you hold overhead for an hour.
Claimed Torque vs. Measured Torque
We did not find a published, instrumented torque measurement for the 2967 that we could cite, so every torque figure in this article is a Milwaukee claim. That matters, because manufacturer maximums tend to be best-case numbers. AutoGuide’s 2023 coverage cited a Torque Test Channel measurement of 778 ft-lbs for Milwaukee’s earlier high-torque wrench and argued that Milwaukee’s headline numbers tend to run high. That was a different model, so it isn’t proof about the 2967, but it is a good reason to treat the 1,100 / 1,500 ft-lbs figure as a ceiling, not a guarantee. If a hard measured number matters to your decision, look for a current instrumented test before you buy. Our guide to why an impact wrench won’t remove lug nuts covers the same “max torque is a marketing number” problem in more depth.
Is It Overkill for Lug Nuts?
For a typical passenger car, usually yes. A mid-torque wrench has plenty of breakaway torque for lug nuts, and a high-torque wrench makes it easier to overtighten when running nuts on. The 2967 earns its size on trucks, heavy equipment, and seized hardware. Either way, use the impact wrench to remove lug nuts or run them on lightly, and finish with a calibrated torque wrench to your vehicle manufacturer’s specification.
Batteries and the M18 Platform
The 2967 runs on Milwaukee M18 batteries, and Milwaukee says its M18 batteries work with more than 300 M18 tools. If you’re deciding whether to commit to the Milwaukee platform in the first place, our comparison of DeWalt, Milwaukee, and Makita battery platforms walks through the trade-offs. Battery capacity matters for a heavy-draw tool like this one, as we explain in our 2Ah vs. 5Ah battery guide. If you want the higher 1,200 / 1,600 ft-lbs rating, you’ll need a FORGE battery, and it’s worth checking current availability first: Milwaukee’s own product page for the FORGE XC6.0 carried a “no longer available” notice when we checked, so confirm what’s currently sold before you buy.
Accessories Worth Buying With It
NEIKO 02448A 1/2″ Drive Master Impact Socket Set, 65-Piece
Any impact wrench needs impact-rated sockets. Regular chrome sockets aren’t designed for repeated impact loads, and this tool delivers a lot of them. Our guide on impact sockets vs. regular sockets explains the difference in full.
Pros: SAE and metric coverage in both deep and shallow sizes; includes extension bars, a ratchet, and adapters; covers the 1/2-inch drive size this wrench uses.
Cons: Heavy and bulky to store as a full case.
TEKTON SIF92400 1/2″ Deep Thin Wall Impact Flip Socket Set
A dedicated lug nut set with thin walls for clearance around decorative wheel caps, useful if you’ll use this wrench on wheels.
Pros: Thin-wall design built for lug nut wells; flip design covers two sizes per socket; radiused corners help reduce round-off on worn lug nuts.
Cons: Lug nut sizes only, not a general-purpose set.
Milwaukee 2967-21B vs. DeWalt DCF900B
| Spec | Milwaukee 2967-21B | DeWalt DCF900B |
|---|---|---|
| Claimed fastening / breakaway torque | 1,100 / 1,500 ft-lbs (kit battery) | 1,030 / 1,400 ft-lbs |
| Length | 7.6 in | 8.8 in (retailer listing) |
| Weight, bare tool | 5.9 lbs (Pro Tool Reviews) | 6.4 lbs (retailer listing) |
| Max speed / impact rate | 2,000 RPM / 2,400 IPM | 2,300 RPM / 2,200 IPM |
| Anvil | Friction ring | Hog ring |
| Low-torque control | Mode 4: 50 ft-lb forward limit, bolt removal control in reverse | Precision Wrench mode |
| Battery platform | Milwaukee M18 | DeWalt 20V MAX |
On paper the Milwaukee is a bit more powerful, shorter, and lighter. Both sets of figures are manufacturer claims from different sources, and we found no head-to-head instrumented test, so we can’t tell you which one actually performs better on a stubborn nut. The practical way to choose is by battery platform: if you already own M18 batteries, the 2967 is the natural fit, and if you already own DeWalt 20V MAX batteries, look at our DeWalt DCF900B review.

The kit includes the 2967-20 impact wrench, one M18 REDLITHIUM XC5.0 Resistant battery, an M18 and M12 multi-voltage charger, and a contractor bag. Check the Amazon listing for the current contents.
What is the difference between the 2967-20 and the 2967-21B?
The 2967-20 is the bare tool with no battery or charger. The 2967-21B is the same wrench packaged with one XC5.0 battery, a charger, and a bag.
How much torque does the 2967-21B really have?
Milwaukee claims up to 1,100 ft-lbs fastening and 1,500 ft-lbs nut-busting torque with the kit’s XC5.0 battery, and up to 1,200 / 1,600 ft-lbs with a FORGE battery. Those are manufacturer maximums, and we did not find an independent measured figure for this model.
Is the 2967-21B good for lug nuts?
It has more than enough claimed breakaway torque, especially for trucks and heavy equipment. For a passenger car a mid-torque wrench is usually enough, and you should still finish tightening with a torque wrench.
Does the 2967-21B work with my existing Milwaukee batteries?
Yes. It runs on Milwaukee M18 batteries, and Milwaukee states that all M18 batteries are compatible with M18 tools and chargers. The higher torque rating needs a FORGE battery.
Can I use regular chrome sockets on it?
No. Use impact-rated sockets only. Regular chrome sockets are not designed for repeated impact loading.
Is it brushless?
Yes. Milwaukee describes it as having a POWERSTATE brushless motor.
What warranty does it have?
Retailer listings and Pro Tool Reviews describe a 5-year limited warranty on M18 cordless tools. Confirm current terms, including battery coverage, directly with Milwaukee before you buy.
Final Verdict
The Milwaukee M18 FUEL 2967-21B is a strong, compact high-torque wrench, and the kit gives you everything you need to start using it. It earns its place for trucks, equipment, and stubborn hardware, and its Mode 4 controls are genuinely useful. Its limits are weight (7.5 lbs with the battery), a headline torque figure that needs an extra FORGE battery to reach, and the fact that most passenger-car work doesn’t need this much wrench. Buy it if you’re already on the M18 platform or committed to it, pair it with impact-rated sockets, and finish wheels with a torque wrench.
Our Pick
Milwaukee M18 FUEL 2967-21B Kit
