Compact SDS Rotary Hammers Compared: Bauer, DeWalt and Ryobi Put to the Test

Introduction

Cordless SDS rotary hammers have quietly become the closest thing to a portable air hammer, at least in terms of size and price. In a recent comparison, three compact SDS Plus models went up against each other in raw impact force, trigger control, weight, price and real-world concrete drilling. The results were not close, and one bargain tool in particular turned heads. This guide breaks down all three so you can pick the right compact rotary hammer for your needs.

The Contenders at a Glance

The Bauer 2144C-B is the newest brushless addition to the Bauer line and its first entry in the SDS category. It is a half-inch SDS Plus rotary hammer, about as small as these tools get, and at $90 it is remarkably cheap for cordless SDS, essentially unheard of at this price point. It is a compact package but still larger than an air hammer by far.

The DeWalt DCH072 is a 12-volt Extreme 9/16-inch SDS Plus model, noticeably smaller and lighter than the Bauer at 3.75 pounds versus the Bauer’s five pounds. At 9.9 inches in length, it is close in size to a medium barrel air hammer and shorter than many long barrel air hammers. It costs $179.

The Ryobi P222 is the lightest of the three at 3.5 pounds and costs $119. It is a fairly simple brushed tool, chosen in the comparison partly because Bauer claims its brushless power should be weighed against this older brushed design.

Features and Handling

The Bauer is surprisingly feature-rich for the money. It offers hammer-only mode, drill-only mode, and combined hammer-and-drill mode, along with a very convenient push-button depth gauge that holds its length without needing to loosen the handle. With a 5 amp hour battery (the brand suggests 3 amp hours and above), it remains a reasonably compact package.

The DeWalt has a notable drawback in its mode selection: the dial only clicks into two positions, drill-only and hammer-and-drill, with no hammer-only mode. Reaching the depth setting also requires loosening and repositioning the side handle, which testers found clunky and annoying. The Ryobi, in contrast, does include the hammer-only mode, though it is otherwise a basic tool.

Impact Power Test Results

In a max power impact test using a domed hammer bit, the differences between the three were dramatic. The Ryobi P222 managed just 714, the lowest reading seen from any tool in this kind of testing. The DeWalt DCH072 reached 1122, a solid step up. The Bauer, however, posted 1770, a standout figure that roughly doubled the Ryobi’s output.

With freshly charged batteries in a best-case run, the pattern held: Ryobi 828, DeWalt 1194 with its 5 amp hour 12-volt battery, and Bauer 1915. The Bauer could not crest 2000, but it was far ahead of the pack.

Trigger control told a different story. The Bauer was actually the worst of the three at dialing power back, though all three differences amounted to peanuts in practice. On the comparison scoring system, which weighs best-case power, trigger control, power per inch of length, power per pound of weight and price, the totals landed at 144.8 for the Ryobi, 206.7 for the DeWalt and a dominant 326.9 for the Bauer.

Can They Replace an Air Hammer?

The short answer: not really. When compared against air hammers previously tested, the closest match in performance was a Dynamic Power short barrel air hammer, itself a mid-tier performer, not a heavy hitter. A $15 Harbor Freight medium barrel air hammer outperformed all three SDS models by a wide margin, and those compact SDS tools were judged barely capable of separating a tie rod or ball joint, much less knocking out a pressed ball joint or dislodging a wheel hub.

For breaking and hammering away from an airline, a full-size high-capacity rotary hammer remains the higher-effort, higher-comfort route. Compact SDS Plus models simply do not hammer with the force of a dedicated air hammer, and the hope of a truly cordless air hammer replacement remains a distant dream for now.

Concrete Drilling Performance

Where the Bauer’s extra impact force really showed was in drilling holes into decades-old concrete sidewalk slabs. The difference in drilling speed and hole quality mirrored the impact power results, and it was not close. More impacting force translated directly into faster concrete drilling with carbide-tipped bits.

That said, all three are capable of drilling concrete to a useful degree. If drilling holes is your primary use, the power gap matters less than it does for breaking work, but the Bauer’s dominance here makes it hard to ignore at its price.

Buying Advice

For pure value, the Bauer 2144C-B is the clear winner. It costs the least, delivers roughly twice the impact power of the Ryobi, has the best feature set including hammer-only mode and a push-button depth gauge, and led every comparison metric with a total score of 326.9.

The DeWalt DCH072 makes sense if you want the smallest and lightest option, or if you are already invested in a 12-volt battery platform, though the missing hammer-only mode and awkward depth adjustment are real compromises.

The Ryobi P222 suits Ryobi One+ owners who want the lightest tool at a modest price, but its impact numbers lag far behind and it is the least compelling of the three on raw performance.

Conclusion

If your goal is a compact, affordable cordless rotary hammer for drilling into concrete and occasional light hammering, the Bauer 2144C-B is the standout pick, combining brushless power, a full mode set and a $90 price that undercuts everything else in its class. Just keep in mind that no compact SDS Plus model here can truly replace a dedicated air hammer for heavy automotive breaking work.
