Coose Power Tools That Run on Milwaukee, DeWalt, and Makita Batteries: Tested From Compact to High Torque

Introduction

A growing category of tools sold on Amazon accepts batteries from major brands without being made by those brands. These Coose drills and impact wrenches run on Milwaukee M18, DeWalt 20V XR, and Makita LXT packs, which means if you already own a healthy battery collection, the tool itself can cost as little as 50 to 120 dollars out the door with no extra batteries required.

That is the appealing part. The risky part is performance: some of these tools genuinely punch above their price, and others should not exist. We tested six Coose models across compact, mid-torque, and high-torque impact wrenches plus a hammer drill to find out which is which.

How These Tools Were Evaluated

Each tool was tested in a best-case fastener-breakaway scenario, measuring the peak torque it could produce, and the hammer drill was additionally measured on raw stall torque with a brake dyno setup. Where possible, tools were run with multiple battery types to see how much battery choice changes results, since that is one of the main selling points of this whole category.

Two questions drove the evaluation: do these tools stack up to the genuine articles they borrow batteries from, and do they at least beat the average unbranded Amazon tool? The answers vary wildly, which is exactly why this lineup is worth reading through carefully.

Compact Impact Wrenches

Coose Compact Impact Wrench (DeWalt 20V Battery)

Rated at 250 ft-lbs and priced at just 50 dollars, this one looked like an easy recommendation on paper. In testing it managed only 122 ft-lbs, a result so poor that it underperformed even cheap knockoff tools we have handled before. It left fasteners loose enough to back off by hand, and even judged as an impact driver it would sit near the bottom of comparable rankings.

Skip this one in any battery variant sold. At this price the appeal is real, but the tool simply does not deliver usable fastening power.

Coose Compact Impact Wrench (Makita LXT Battery)

This is a very different story. Taking Makita LXT batteries and sold in a kit with its own charger for roughly 75 to 80 dollars, this compact produced 272 ft-lbs in testing with a 5.0Ah Makita pack, beating the genuine DeWalt ultra-compact in the same test. It would not break free 350 ft-lbs fasteners, but its forward working torque mixed it up with far more expensive tools.

It is one of the top one or two compacts we have tested from Amazon sellers, and a huge step up from its DeWalt-battery sibling above. Note that the included in-house 4.0Ah battery is typically not as strong or as long-lasting as a real Makita pack, but the tool performs respectably either way.

Drills

Coose Cordless Hammer Drill (M18 Battery)

At 60 dollars with a metal chuck, this hammer drill advertises 792 inch-pounds of torque. It does not pretend to challenge Milwaukee’s flagship M18 hammer drill, but against the average of unbranded Amazon drills we have measured, it does reasonably well: 320 watts of output power puts it above average and just into territory we would consider genuinely useful.

On raw stall torque it produced 15.7 ft-lbs, which widened further to 16.6 ft-lbs with a higher-discharge battery. The gap to the genuine Milwaukee tool remains large, and realistically you can do better even at similar prices from established entry-level brands. It works, but it is not the pick of this lineup.

Mid-Torque Impact Wrenches

Coose Mid-Torque Impact Wrench (M18 Battery)

Rated at 600 ft-lbs and priced at 90 dollars, this mid-torque is larger than Milwaukee’s equivalent, which is the shortest tool in its class, but it stays in the same performance conversation. It produced 436 ft-lbs in testing, respectable for its size and not far off its intended target.

The interesting part is battery sensitivity. With a high-discharge battery it climbed to around 500 ft-lbs, putting it up there with the best the genuine mid-torque competition can manage. That gain is less a credit to the tool and more a sign it needs strong discharge amps and minimal voltage sag to perform at its potential, but for 90 dollars the ceiling is impressive.

High-Torque Impact Wrenches

These two models blur the line between mid-torque and high-torque: both are smaller than the shortest genuine high-torque on the market in every dimension, and one is even shorter than the mid-torque tested above at 6.97 inches versus 7.15 inches. There is little sign of a cohesive design strategy across the lineup, so each was judged on its own numbers.

Coose High-Torque Impact Wrench (Makita Battery)

Priced at 115 dollars, this model produced 497 ft-lbs, which did not punch much above the cheaper mid-torque. With the best-performing 18V battery available, it reached 589 ft-lbs, though the test data showed an unusual performance hump mid-pull that appeared on all three runs and then vanished. That anomaly makes it hard to rank confidently.

At 115 dollars it is genuinely interesting for DIY use, and comparable tools from other value brands can sometimes be found even cheaper, around 85 to 90 dollars.

Coose High-Torque Impact Wrench (DeWalt XR Battery)

This one costs 120 dollars and delivered the biggest battery-driven surprise of the entire test. Starting at 497 ft-lbs, it jumped to 602 ft-lbs with DeWalt’s 9.0Ah XR pack, the strongest battery performance gain we have recorded on a mid or high-torque tool, and a figure knocking on the door of the market’s leading mid-torque. Repeating the test with a 5.0Ah XR confirmed the higher numbers were real, not break-in effects.

One caution: with a Power Stack battery the tool and battery both cut out entirely, though that pack is known to be fussy with unusual loads and revived fine afterward. Treat this tool as a strong value if you already own DeWalt XR batteries.

Buying Advice: Which Coose Tools Make Sense

If you need one compact impact wrench and already run Makita LXT batteries, the Makita-compatible compact is the standout of this lineup and one of the best Amazon-sold compacts we have tested. If you do not already own a mid-torque, the M18 mid-torque at 90 dollars is a surprisingly capable entry point, with the caveat that unlocking its full potential may require a battery that costs several times more than the tool itself, so it only makes sense if you already have the pack.

The high-torque models are best treated as occasional-use tools: the kind of thing you pull out to rotate tires or swap brakes at home rather than a daily driver. If you make a living with your tools, the genuine branded options remain the safer buy. The DeWalt XR high-torque is the more interesting of the two if your battery drawer already holds XR packs.

Conclusion

This category is a mixed bag, and the differences between models from the same seller are enormous. The compact DeWalt-battery impact wrench is best avoided outright, the drill can be beaten at similar prices, but the Makita compact, the M18 mid-torque, and the DeWalt XR high-torque all deliver genuine value for someone who already owns the matching batteries. Buy the ones that match your existing battery collection, and let the tool do the rest.
