Best Cordless Ratchets Compared: DeWalt, Craftsman, Kobalt, and Milwaukee Tested

Introduction

Cordless ratchets look similar on the shelf, but the numbers they post in real use turn out to be anything but similar. We lined up five of them from the hardware store aisle: the newly released DeWalt 20V Atomic DCF513, the Craftsman V20 CMCR930B, the Kobalt 24V KRW 124B-03, DeWalt’s 12V Xtreme, and the Milwaukee M12 extended-reach model.

Some results genuinely surprised us. Not every tool made it through testing intact, and only one ratchet in this group earned an unqualified recommendation.

How These Ratchets Were Evaluated

Every tool faced the same gauntlet: a timed run through bolts fitted with nylon lock nuts ranging from 4 to 15 foot-pounds of resistance, simulating rust or imperfect threads. Free speed ratings turned out to mean very little once a load was applied, so real times under load became the true divider.

We also measured max torque with a trigger pull and by hand, weighed each tool, compared head sizes for access in tight spaces, and factored in price.

DeWalt DCF513 20V Atomic Ratchet

The DCF513 is the newest tool here, rated at 250 rpm and 70 foot-pounds, priced at $199, about $20 more than the 12V version. The Power Stack battery keeps the weight about the same as the 12V model, which makes the 20V format reasonably manageable compared with other bulkier 18/20V ratchets, and its 1.49-inch head is actually narrower than the 12V’s 1.55-inch head.

The twist: in the gauntlet it ran slower than its own 12V sibling at every step, finishing in 160 seconds. Trigger-pull torque measured 72 foot-pounds, up to 78 with a larger battery, and by hand it felt solid all the way to about 175 foot-pounds. It is a capable tool, but it costs more and works slower than DeWalt’s smaller option, which is why it ranks below several cheaper rivals.

Craftsman V20 CMCR930B Ratchet

At $99 and rated 35 foot-pounds with a claimed 300 rpm, the Craftsman is the budget pick of the group. Its high rpm rating held up, and it moved ahead on smaller fasteners, finishing the gauntlet fastest overall at 2 minutes 51 seconds, helped by a smaller head on paper.

There are real caveats, though. The narrow head is undercut by large shoulders close to it, so the access advantage is limited. Trigger-pull torque measured 32 to 36 foot-pounds, about right for the rating, and on smaller nuts it needed hand assistance earlier than most tools tested. More seriously, the ratchet skipped and then seized up completely during high hand-torque use, and it did not sound healthy afterward. For $99 it is quick and affordable, but durability under strain is a genuine question.

Kobalt 24V KRW 124B-03 Ratchet

The Kobalt advertises 250 rpm and 55 foot-pounds for $129, and rumor had it this thing punches above its torque rating. That proved true. With a 2Ah battery it measured 66 to 70 foot-pounds; with the 4Ah Ultimate Output battery it reached 80 to 82 foot-pounds, well above its claim.

It was the only ratchet in this group that could loosen some of the toughest nuts at the end of the gauntlet with just a trigger pull, and its longer body allowed hand use past 200 foot-pounds without issue. The trade-offs are weight, at 4.1 pounds it is the heaviest here, and a large head, though the rotating top switch obstruction matters as much as head size. It finished the gauntlet in 3 minutes 13 seconds, nearly matching the far more expensive Milwaukee M12 extended-reach. For the footprint, torque, and price, this was a standout buy.

DeWalt 12V Xtreme Ratchet

The quiet star of this comparison. Rated at the same 250 rpm as the Atomic but with 60 foot-pounds claimed, the 12V Xtreme ran faster under load than the 20V model consistently at every step of the gauntlet, at roughly 3.5 rpm on larger threads versus the 20V’s 2.5 to 3. The Atomic only occasionally avoided a hand assist where the 12V needed one.

An owner’s own measurement backed this up: about 290 rpm free speed for the 12V versus 260 for the Atomic, so the rated numbers may not tell the whole story. It is smaller, cheaper at around $179, and nearly as torquey in practice. Against almost everything else tested in this category, it sits near the top. If you want a DeWalt ratchet, this is the one to get.

Milwaukee M12 Extended-Reach Ratchet

The Milwaukee M12 extended-reach is rated 55 foot-pounds at 200 rpm for around $100. Its head is thicker in real life than the Kobalt’s, but the Kobalt’s rotating top switch takes up as much or more room, so these two ended up the most evenly matched pairing in the whole test, despite one being 12V and the other 24V.

The M12 needed some hand assistance on torqued fasteners where the Kobalt did not, but under the heaviest loads it turned faster, about 2.5 rpm versus 1.9. It finished just three seconds behind the Kobalt. If you buy the shorter M12 version instead, you get the same performance for less money, which makes that variant the smarter Milwaukee buy in this category.

Buying Advice: Which Ratchet Makes Sense

If you already own a battery platform, staying in it is fair, and that argument carries real weight here. On pure performance for money, though, the picture is clearer.

The DeWalt 12V Xtreme is the standout: smaller, cheaper, and demonstrably faster than the newer 20V Atomic with nearly the same torque. The Kobalt 24V is the value surprise, offering serious torque above its rating and near-M12 pace for $129. The Craftsman is quick and cheap but had the worst durability outcome we have seen in this category. The DeWalt 20V Atomic is not bad, but it costs more and finishes slower than its own little brother.

Conclusion

The new-and-shiny option is not always the better one. In this group, the DeWalt 12V Xtreme earns the unqualified recommendation, the Kobalt 24V is the best value with real torque overhead, the Milwaukee M12 extended-reach matches it closely at a higher price, the Craftsman V20 is a fast but riskier budget play, and the DeWalt 20V Atomic is a solid tool overshadowed by a smaller sibling that does the job better for less.
