Best Impact Wrench 2026: DeWalt vs Milwaukee vs Bosch vs Makita

Impact wrenches are sized by torque class, and picking the wrong class is the single most common expensive mistake buyers make. All four tools compared here are mid-torque — enough for lug nuts, structural bolts, and most concrete anchor installation, without the extra size, weight, and cost of a high-torque tool most users don’t actually need.

Impact Wrench vs Impact Driver — Which Do You Need?

These are different tools built for different jobs, even though the names sound similar and both use a hammering mechanism:

• Impact drivers use a 1/4" hex chuck for driving screws and small bolts — deck screws, framing fasteners, cabinet installation.
• Impact wrenches use a 1/2" or larger square drive for sockets, and deliver far higher torque through a hammer-and-anvil mechanism built for nuts, bolts, lug nuts, and structural fastening.

If you’re driving screws, see our Impact Driver vs Drill guide instead. If you’re removing lug nuts, tightening structural bolts, or setting concrete anchor nuts, you’re in the right place.

Torque Classes Explained

Cordless impact wrenches fall into three general torque classes. The class you need is determined by your primary job, not by which number sounds most impressive on the box:

• Compact (150–250 ft-lbs): light-duty, automotive trim, small fasteners, tight spaces
• Mid-torque (300–650 ft-lbs): the versatile middle ground — lug nuts, structural bolts, concrete anchors, most trade work. All four tools compared here fall in this class.
• High-torque (800–1,400+ ft-lbs): heavy equipment, large-diameter fasteners, fleet and diesel mechanic work

Buying more torque than you need adds cost, weight, and bulk without practical benefit for most users — a high-torque tool isn’t simply “better,” it’s a different tool for a different job.

Real Specs by Brand

Advertised specs verified against manufacturer product pages — July 2026. Makita’s GWT07Z runs on the 40V XGT platform, a separate battery system from Makita’s 18V LXT lineup — not interchangeable if you already own LXT tools.

Advertised vs. Independently-Tested Torque

Manufacturer torque specs are measured under controlled lab conditions and represent maximum output — real-world performance can differ, sometimes significantly. Pro Tool Reviews tested these tools on an inertia torque rig across multiple rounds:

• DeWalt DCF891 measured 392.6 ft-lbs in one test round and 329.5 ft-lbs in a separate head-to-head — both below its 600 ft-lbs advertised fastening torque
• Milwaukee 2962 measured 412.8 ft-lbs in that same head-to-head — higher than DeWalt’s measured result in the identical test, despite DeWalt’s higher advertised spec

Despite this, DeWalt won “Best Overall” in Pro Tool Reviews’ broader testing — not on raw measured torque, but on application speed. DeWalt’s hammer mechanism strikes harder and faster, completing fastening tasks quicker even when Milwaukee tested with more raw torque in that specific comparison. The lesson: advertised torque is a starting point, not the whole story — impact rate and hammer mechanism matter as much as the peak number for real-world speed.

Matching Torque to the Fastener

Torque isn’t just about raw power — for structural and code-governed connections, hitting the specified torque matters as much as having enough of it. Mechanical concrete anchors are a clear example: Simpson’s Strong-Bolt 2 wedge anchor (ICC-ES ESR-3037) specifies installation torque that scales with anchor diameter, from 30 ft-lbs at the smaller end up to 150 ft-lbs at the largest, per the official ESR report. A 1/2" Strong-Bolt 2 anchor calls for approximately 45 ft-lbs of installation torque.

This is why features like DeWalt’s Precision Wrench mode, Milwaukee’s exact 35 ft-lb Auto Shut-Off, and Bosch’s customizable torque presets matter for more than convenience — over-torquing a mechanical anchor can crack the surrounding concrete or overstress the anchor body; under-torquing leaves it under-engaged. Always check the specific anchor’s ESR report or manufacturer installation instructions for the exact torque spec — the Strong-Bolt 2 figures above are one example, not a universal number across anchor brands or sizes.

DeWalt DCF891B

The DCF891B is DeWalt’s mid-torque entry in the 20V MAX XR lineup, advertised at 600 ft-lbs fastening / 800 ft-lbs breakaway torque. Pro Tool Reviews rated it “Best Overall” in group testing — not for raw measured torque, where it actually trailed Milwaukee in head-to-head testing, but for application speed: DeWalt’s hammer mechanism strikes harder and faster, getting through fastening tasks quicker in real-world use. Precision Wrench mode adds real, specific control: in forward, the tool runs at 2000 RPM until the first impact, then pauses half a second before continuing — reducing the risk of overtightening. In reverse, it automatically slows once the fastener breaks free, preventing dropped hardware.

Milwaukee 2962-20

Part of Milwaukee’s M18 FUEL lineup, the 2962-20 is the most compact tool in this comparison at just 6 inches long — useful for reaching fasteners in tight engine bays or confined structural connections. In Pro Tool Reviews’ own lab testing, it measured 412.8 ft-lbs of torque — higher than DeWalt’s measured result in the same head-to-head test, despite DeWalt’s higher advertised spec. Auto Shut-Off mode caps torque at exactly 35 ft-lbs for hand-tight fastening, a specific, genuinely useful control for setting fasteners without over-tightening by feel.

Bosch GDS18V-330CN

The GDS18V-330CN is Bosch’s mid-torque entry, advertised at 330 ft-lbs fastening / 590 ft-lbs breakaway — the lowest torque numbers of the four, but the only tool here with app-connected customizable torque presets via the Bosch Toolbox App, letting you save specific settings per bolt or fastener type. Auto Bolt Release stops rotation the moment a bolt loosens during removal, preventing dropped hardware without needing a dedicated mode selection.

Makita GWT07Z

The GWT07Z runs on Makita’s 40V max XGT platform — a separate, newer battery ecosystem from Makita’s 18V LXT lineup, worth noting if you’re already invested in LXT tools and expecting battery compatibility. Advertised at 560 ft-lbs fastening / 810 ft-lbs breakaway, it has the highest breakaway torque of the four. Its 3 forward / 3 reverse Auto-Stop modes offer more granular control than the single-mode systems on the other three tools, and XPT sealing adds real dust and water resistance for harsh job site conditions.

Who Should Actually Buy Which

• Already own batteries on one of these platforms? Buy that brand — the performance gap between all four is smaller than the cost of starting a second battery ecosystem.
• Working in tight engine bays or confined structural connections? Milwaukee’s 6" length is notably more compact than DeWalt’s — a real advantage for tight spaces.
• Want app-connected customization and don’t mind lower raw torque? Bosch’s presets are unique in this set.
• Doing structural or anchor work needing precise torque control? DeWalt’s Precision Wrench mode and Milwaukee’s exact 35 ft-lb Auto Shut-Off both offer genuine, specific control — not just raw power.
• Starting fresh with no existing platform, want the highest breakaway torque? Makita’s GWT07Z leads on paper — but confirm you’re comfortable starting the 40V XGT platform rather than 18V LXT.

Recommended Tools by Category

All four are mid-torque class for a fair comparison — stay on your existing battery ecosystem if you have one.
