The DEWALT DCH273B 20V MAX XR SDS Rotary Hammer is a high-performance bare tool designed for professional concrete work. Its brushless motor and German-engineered mechanism deliver 2.1 Joules of impact energy, while the three-mode selector lets you swap between rotary drilling, hammer drilling, and chipping without carrying a second tool.
The DCH273B is part of the DEWALT PERFORM & PROTECT platform and includes SHOCKS Active Vibration Control, which reduces vibration at the handles. That makes long periods of overhead drilling or anchor setting easier on your hands and wrists. The lightweight body is ideal for rod hanging, seismic attachments, cable tray mounting, and clamp installation, where space is tight and you need to maneuver quickly.
For concrete drilling, dust is more than a nuisance—it's a health hazard. The DCH273B is OSHA Table 1 compliant when paired with the DEWALT DWH303DH on-board dust extractor (sold separately). The extractor attaches directly to the tool and captures dust at the point of bit entry, keeping the work area cleaner and helping you stay in line with silica dust regulations. If you are drilling overhead, the onboard extractor also reduces the amount of dust you breathe.
Before first use, review the DCH273B user manual. It covers the correct assembly of the auxiliary handle, depth rod, and SDS-Plus bit insertion. It also includes the proper procedure for changing modes—always rotate the selector with the motor stopped. The manual can be downloaded from DEWALT support by searching for DCH273B. If you need a printed copy, Workbench World support can point you to the right resource.
This is a bare tool, so no battery or charger is included. It runs on any DEWALT 20V MAX battery, which lowers the cost if you already own the platform. The brushless motor wrings more runtime from every charge and delivers consistent speed under load. With a 5Ah battery, you can handle most anchor drilling and light chipping tasks without recharging.
For electricians, mechanical contractors, and anyone who mounts heavy items to concrete, the DCH273B gives you reliable power in a one-handed-sized package.

The SHOCKS Active Vibration Control system in the DCH273B makes a measurable difference on anchor drilling. The vibration dampening is engineered into the handle, not just the housing, so you feel less fatigue and can drill more accurate holes in tight positions. This is especially beneficial on ladders or when drilling overhead.
Pairing the DCH273B with the DWH303DH dust extractor not only helps you meet OSHA Table 1 requirements—it keeps the work area visible and reduces cleanup time. The extractor is designed specifically for this tool, so it doesn't upset balance or make the tool bulky. You'll spend less time sweeping and more time on the next hole.
Buying a bare tool makes sense if you already own DEWALT 20V MAX batteries. The cost savings goes directly into your wallet, and you can choose the battery capacity that matches your day. The DCH273B is compatible with all DEWALT 20V MAX packs, from compact to high-capacity.
No, this is a bare tool. It works with all DEWALT 20V MAX batteries and chargers.
The DEWALT DWH303DH on-board dust extractor attaches directly to this model and is the recommended attachment for OSHA Table 1 compliance.
The manual is available on DEWALT's support website. Search DCH273B and download the PDF. You can also contact Workbench World support and we'll help you locate it.
It uses SDS-Plus bits, which are the standard for 1-inch-class rotary hammers. They lock securely and transfer the impact energy into the concrete.
Yes, in chipping mode you can use SDS-Plus chisels for light chipping, tile removal, or breaking small sections of masonry. For heavy breaking, a larger rotary hammer would be better.
Powerful hammer.
I've used this for drilling into concrete. It's very effective. The vibration control really helps.
As a professional mason, I rely on this hammer daily. The 2.1 joules of impact energy drill through rebar easily. It has three modes, which is convenient. The active vibration control reduces fatigue significantly. The brushless motor runs efficiently. It's a bare tool, but I have plenty of batteries. I'm very pleased.
Solid tool.
Great hammer for the price. It handles concrete and brick well. The body is comfortable.
I bought this to mount things on my basement walls. It works great. The hammer mode is strong. The chisel mode is useful for removing old tiles. It's a bit heavy, but that's expected. The battery life is decent if you use a good battery. I recommend it.
Very effective.
Good rotary hammer. The SDS chuck holds bits securely. It's easy to control.
I've used many drills, but this is my first rotary hammer. It made drilling into concrete feel like butter. The vibration control is noticeable. The three modes are easy to switch. I wish it came with a side handle, but that's optional. It fits my existing 20V batteries. Overall, a great tool.
Gets the job done.
It works well, but it's bare tool so you need batteries. I already had them. Good performance.
I'm a contractor and I've used this on many job sites. It's durable and powerful. The SDS system is reliable. The brushless motor lasts all day with a 5Ah battery. The only downside is the lack of a depth rod, which I had to buy separately. Otherwise, it's excellent.
