Excellent at loosening, and never the tool that finishes the job · review
The highest cordless torque here, with fastening and breakaway published separately — and no battery in the box.
The last word It publishes both torque figures, which is what this shelf asks for, and the highest of each among the cordless tools. The battery is the other half of the price.
A 1/2-inch cordless impact wrench on the 20V MAX platform with 1030 ft-lb of maximum fastening torque and 1400 ft-lb of maximum breakaway torque, a brushless motor, 4-mode speed settings with a variable-speed trigger, Precision Wrench control, a hog ring anvil, an LED work light and Battery Guard — a shock-absorbing battery-to-tool connection. Tool only: battery sold separately. $194.00.
The introduction is blunt about why: makers “publish two different numbers for it: fastening torque and the much larger breakaway torque, which is what it can loosen. Comparing one brand’s breakaway figure with another’s fastening figure is the most common mistake on this shelf.”
| Tool | Fastening | Breakaway |
|---|---|---|
| This tool | 1030 ft-lb (1,396 N·m) | 1400 ft-lb (1,898 N·m) |
| DCA ADPB520 | 383 ft-lb (520 N·m) | 503 ft-lb (682 N·m) |
| VEVOR air, published | 6,711 N·m working | 7,016 N·m breakaway |
| MAGSEN | — | — (1,200 N·m “maximum”) |
| Robustrue | — | — (800 N·m “maximum”) |
| Dong Cheng, published | — | — (800 N·m “maximum”) |
| KS Tools air, published | — | — (1,600 N·m) |
| Bosch, published | — | — (215 N·m) |
| Einhell, published | — | — (none published) |
Three of the nine tools on this shelf publish both. On the cordless half, this one and the DCA are the only two — and the gap between the two DEWALT figures, 370 ft-lb, is the size of the mistake the introduction warns about.
Both figures are the highest of any cordless tool here. 1400 ft-lb of breakaway is 1,898 N·m, which is more than the published air-powered KS Tools wrench at 1,600 N·m and a quarter of the published one-inch VEVOR air wrench at 7,016 N·m.
For context, a car wheel nut is tightened to roughly 110 to 140 N·m. This loosens at thirteen times that, which is the figure that matters on a suspension bolt that has been on for ten years.
“Designed To Help Prevent Overtightening And Fastener Run-Off.” And: “Precision Wrench control adds extra safety and control, especially for critical fastening tasks.”
The rule at the top of this shelf: “an impact gun loosens wheel bolts, and a torque wrench finishes them.”
DEWALT does not claim otherwise. “Help prevent” and “extra control” are hedged words, and fastener run-off is the specific failure they name — the moment a nut comes free and the gun spins it off the stud and onto the floor. Precision Wrench is a mode that slows the tool as the fastener breaks loose.
Nothing here is presented as a substitute for a torque setting, which the published Bosch wrench’s “automatic shut-off and automatic slow-down” also is not. This site’s torque wrenches shelf is what finishes the job.
“Increase user control in a variety of applications — with 4-mode speed settings and variable speed trigger.”
Four modes and four unstated torques. Compare:
| Tool | Stages | Torque per stage published |
|---|---|---|
| DCA ADPB520 | 4 | 350 / 420 / 520 N·m, plus 682 nut-busting |
| MAGSEN | 3 | 500 / 800 / 1200 N·m |
| Dong Cheng, published | 3 | 431 and 507 N·m among them |
| This tool | 4 | none |
| Robustrue | 3 | rpm only — 2000 / 2200 / 2800 |
The published Dong Cheng page makes the point for the whole shelf: publishing the torque of the stages “is what makes a selector usable”. A four-position dial whose positions are unlabelled in N·m is set by feel, which on a 1,898 N·m tool is a wide band of feel.
A hog ring anvil retains the socket with a spring-steel ring instead of a detent pin, so sockets change by hand with no tool and stay on under load. The DCA wrench here publishes the same, and calls it out for “frequent swaps (tire service)”. No other tool on this shelf names its anvil type.
Battery Guard is “a shock-absorbing battery-to-tool connection”. On an impact tool that is not cosmetic: the whole tool hammers, and the battery’s terminals and latch take every blow. Nothing else on this shelf publishes anything about the battery mount.
“tool Only (DCF900B)… (battery sold separately).”
| Tool | Price | Batteries included |
|---|---|---|
| DCA ADPB520 | $44.99 | 2 × 4.0 Ah |
| Robustrue RT800B | $89.99 | 2 × 4.0 Ah |
| MAGSEN | $99.99 | 2 × 4.0 Ah |
| This tool | $194.00 | none |
The introduction frames the platform as the real decision: “The second consideration is the battery platform — the tool is cheap and the ecosystem is not.”
That cuts both ways here. 20V MAX is one of the two or three largest cordless platforms sold, which means a buyer who already owns DEWALT batteries pays $194 and nothing more, and a buyer who does not pays $194 plus a battery and charger. The three cordless tools above it on price all run proprietary packs that nothing else uses.
The published Einhell wrench makes the same argument from the other side: “comes with a battery, so the price is the real price.”
“the third is weight, because this is held at arm’s length under a wing.”
DEWALT publishes none. The shipping record gives 2,903 g (102.4 oz) for the packed tool, which includes the box and no battery, and is not a maker figure.
| Tool | Stated weight |
|---|---|
| Robustrue | 3.74 lb (1.70 kg) with battery |
| DCA | 4.4 lb (2.0 kg) with battery |
| Dong Cheng, published | 2.2 kg (4.9 lb) with battery |
| MAGSEN | 10 lb (4.5 kg) |
| This tool | not published |
A 20V MAX 5 Ah pack is itself about 0.7 kg (1.5 lb), so this is not a light tool — and the figure is not there to plan around.
No weight. No torque per mode. No length — the shipping record gives 270 × 252 × 105 mm for the package. No impact sockets supplied, where the MAGSEN and Robustrue tools here ship five and four; the buying advice for this shelf is that chrome sockets “fail by shattering rather than by deforming”. No battery or charger. No impacts per minute. No warranty term in the listing.
At $194.00 it is the most expensive tool on this shelf, the strongest cordless one, and the only one whose price does not include what makes it run.
On sale at around $194 on the American Amazon store at the time of checking.

Because they measure opposite jobs. Fastening torque is what the tool can tighten to; breakaway torque is what it can crack loose, and it is always the larger number — here 1030 against 1400 ft-lb, a gap of 370. The shelf’s introduction calls comparing one brand’s breakaway with another’s fastening "the most common mistake on this shelf", and only three of the nine tools here publish both.
Spin them on, yes; finish them, no. DEWALT is careful about this — "designed to help prevent overtightening and fastener run-off" is a hedge, not a torque setting, and the four modes publish no N·m figure. The rule at the top of this shelf does not move: "an impact gun loosens wheel bolts, and a torque wrench finishes them." This site has a torque wrenches shelf for that.
It depends entirely on what is already in your garage. The introduction says "the tool is cheap and the ecosystem is not" — and 20V MAX is one of the largest platforms sold, so an existing owner pays $194 and nothing else. Someone starting fresh pays $194 plus a battery and charger, against $44.99 for the DCA tool here with two 4.0 Ah batteries on a platform nothing else uses.
