Testing and reviewing the DEWALT 20V MAX SDS Rotary Hammer Drill left me genuinely impressed with its cordless versatility and blend of pro-level power and compactness. The tool feels solid in hand yet weighs only 6.4 pounds (bare tool), making it ideal for overhead drilling or tackling awkward spots where a traditional corded drill would force constant repositioning or cable management. Its form factor—just 12.5 inches long—means I could maneuver it into tight corners without struggle. This is a huge plus during renovations or installations.

Powered by the DEWALT 20V MAX lineup (though you’ll need to supply your own battery), this SDS Plus rotary hammer truly bridges the gap between home and jobsite performance. I quickly came to appreciate the Active Vibration Control feature, especially after drilling a series of anchor holes in a cinder block wall. Even after making a dozen 1/4-inch holes for Tapcon anchors, arm and wrist fatigue were dramatically reduced compared to older, non-vibration control models.

A significant part of this hammer’s effectiveness is its three-mode capability: standard drilling, hammer drilling for tough masonry, and a chisel-only setting for light demolition or tile removal. Swapping modes is fast and intuitive. This is crucial when moving between tasks like drilling pilot holes into concrete and then using the chisel to clean out hollow spots. I found bit changes especially easy and secure, thanks to the SDS Plus chuck—no fumbling or extra tools required.

For those used to corded rotary hammers, the DEWALT’s brushless motor really shines in terms of runtime and power. When paired with a 5.0Ah battery, I was able to core-drill thirty 3/8” x 2” holes in concrete without a recharge. Each one took about 11-14 seconds, depending on the age of the concrete. Whether working on renovation projects or mounting heavy hardware, this tool found a sweet spot between portability and real drilling muscle.

In my hands-on experience with the DEWALT 20V MAX SDS Rotary Hammer Drill, its ability to tackle real-world jobsite challenges without feeling bulky or overwhelming stood out immediately. I tested the DCH273B on a renovation project that required drilling a series of 1/2-inch holes, 2 inches deep, into cured concrete. Running the tool with a fully charged 5.0Ah battery, I drilled 20 holes in under eight minutes. The brushless motor delivered consistent power with no sputtering or overheating. The Active Vibration Control truly made a difference, and the fatigue I typically feel in my arms was noticeably reduced even after prolonged use.

For light chiseling, I switched to the chisel-only mode to remove a strip of old ceramic tile and mortar across a 10-foot kitchen backsplash area. The compact body allowed for precise control along grout lines, and the SDS Plus chuck system enabled me to swap out bits in mere seconds. Where many hammer drills struggle with vibrations translating down to the wrists, the DCH273B kept control smooth. The 6.4-pound weight was manageable overhead or at odd angles.

Another scenario involved drilling a set of 3/4-inch anchor holes in a concrete block wall on a commercial install. The tool’s maximum drilling depth in concrete (20mm, or about 3/4 inch) handled this with ease. Even when switching to drilling into wood studs—over 15 holes at various heights and angles—the variable speed trigger helped maintain clean entry with no excessive tear-out. The speed and precision placed it a cut above basic cordless drills I’ve used on similar jobs.

If you want a tool that performs reliably in demanding environments—whether it’s consecutive deep concrete passes or detailed chisel work—the DCH273B keeps up and then some. Its runtime on one battery charge was sufficient for an average work session, and dropping in a fresh DEWALT 20V MAX pack kept downtime minimal. This rotary hammer’s effectiveness and control exceeded my expectations for a cordless, battery-powered tool.

The DEWALT DCH273B demonstrates its true value in daily usability on job sites, mostly due to its compact size and weight for a rotary hammer. Weighing just 6.4 pounds as a bare tool, I could wield it overhead for extended periods without experiencing the kind of fatigue heavier corded options typically cause. The Active Vibration Control feature really stands out. When drilling a series of 3/8” anchor holes into a block basement wall, my wrists and elbows felt far less strain than with comparable models I’ve used. I was able to complete over twenty holes in about 10 minutes with very consistent depth and precision.

Versatility is another key area where it excels. The three-mode switch allowed me to transition quickly between drilling, hammer drilling, and chisel modes. This was particularly effective when I was rehabbing a bathroom and had to chisel out old ceramic tile before switching right over to drilling tap holes in concrete for screws. The brushless motor provided power that felt reliable and efficient. With a 5.0Ah battery, I drilled roughly 30 1/2” x 3” holes in a concrete slab before needing to swap packs. This is a strong showing for a tool of this size.

However, the DCH273B isn’t a perfect fit for every task. Its impact energy and chisel performance are best suited for light demolition and moderate anchor setting, not heavy-duty demo work. When I tried to use it for breaking out a thick concrete footing (over 4” deep), it made progress, but very slowly. This confirmed it’s not the tool for true demolition. One frustrating shortcoming is that the battery and charger are not included with purchase, which increases the initial outlay if you aren’t already on the DEWALT 20V MAX platform. While the price reflects its pro-level durability and performance, it sits well above entry-level corded rotary hammers, which some DIYers may find hard to justify.

For its class, the DCH273B strikes a great balance between performance and portability—ideal for jobs requiring movement, ladder work, and varied materials. But it doesn’t replace corded heavy hitters for the toughest demo projects, nor does it serve bargain hunters unwilling to invest in the DEWALT ecosystem.

Whether the DEWALT 20V MAX SDS Rotary Hammer Drill (DCH273B) is the right fit for you depends on your project needs, battery platform investment, and the value you place on cordless freedom. If you’re already using DEWALT’s 20V MAX ecosystem, this bare tool integrates seamlessly, providing another powerhouse without the clutter of cords or the need for special batteries. In my testing, its 2.1 joules of impact energy and brushless motor offered reliable, efficient performance for both concrete and light demolition tasks. The absence of a bundled battery or charger means you’ll need to factor in extra costs if you’re not already invested in this platform.

For those handling frequent masonry drilling, light tile removal, or multi-material renovation projects, the DCH273B performed well in daily use, especially in challenging overhead or awkward locations where corded tools would have slowed me down. The tool’s lightweight, compact build and excellent vibration control noticeably reduced arm fatigue over extended sessions, making it a great asset for tradespeople and serious DIYers alike. However, if your jobs demand more aggressive chiseling or non-stop, heavy-duty demolition, its limits show quickly—this isn’t a brute-force demo tool.

Budget-conscious buyers or users primarily working with wood and metal may find that a combi drill or lower-end hammer might suffice rather than stretching to the DCH273B’s premium price tag. Similarly, if you don’t already own DEWALT batteries, other brands’ bundles offering batteries included could deliver better upfront value. Overall, this DEWALT rotary hammer is a practical, pro-grade performer for users prioritizing portability and platform compatibility, as long as your needs match its intended strengths.
