DEWALT DCH273B 20V MAX SDS Rotary Hammer Drill

A cordless rotary hammer like this is mainly for people who spend time around concrete, masonry, or repeated drilling jobs and want one tool that can cover more than a standard drill. The DCH273B is the kind of bare tool that makes sense if you already have batteries and chargers in the 20V MAX line, or if you are building out a work kit one piece at a time. It is not the sort of tool you buy for occasional shelf hanging in drywall. It is for tougher material, more frequent use, and the kind of job where a regular drill starts feeling underpowered.

The appeal is straightforward. An SDS rotary hammer brings a different drilling action than a standard drill or impact driver, and that matters when the material gets hard. Three application modes also give it more range than a single-purpose tool, which can matter on a worksite where one job turns into three. For someone putting together an everyday construction setup, that flexibility is often the point. A tool like this can help reduce the number of separate tools you need to pull out for anchor holes, light chiseling, or standard rotary hammer work, depending on the task and the bits you use.

Because this is the bare tool version, the main thing to verify is what you already own. Batteries, charger, and compatible SDS bits are the real hidden cost if you do not already have them. That is not a flaw in the tool itself, but it does affect whether the purchase makes sense. It is also worth checking whether the weight and grip feel right for your kind of work, especially if you expect to use it overhead or for longer stretches. A rotary hammer is a more specific tool than a general-purpose drill, and that specialization cuts both ways.

The evidence here is limited to the product's stated role as an everyday construction tool, so the safest reading is about fit rather than claimed performance. The title points to cordless operation, three application modes, and SDS rotary hammer design, which are the features that usually matter most when someone is deciding between a basic drill and a more serious hammering tool. What you should confirm is whether those features line up with the materials you work with most often and whether you already have the battery platform to support it.

This may fit a contractor, remodeler, or hands-on homeowner who already works with concrete or masonry often enough to justify a dedicated tool. It also makes sense for someone who wants to stay inside one battery system and avoid buying a separate corded setup. If your jobs are mostly light-duty, this is probably more tool than you need. If your work regularly calls for drilling into hard material, this is the sort of tool that belongs in the lineup rather than the toolbox as a backup.
