Powerful, versatile, and surprisingly compact — professional performance in a manageable format
I have been using the DeWalt DCH273 SDS Rotary Hammer in concrete drilling work, masonry, and some light demolition tasks, and the experience has been very positive in all key aspects. The first thing that stands out is its very good power. Despite being a relatively compact tool, it has the capacity to drill hard materials easily, maintaining constant and reliable performance. The impact force is notable, which allows rapid progress in drilling without having to apply excessive pressure. Another strong point is its chiseling function, which greatly expands its range of use. It is not only for drilling, but also for material removal or adjustments on surfaces, which makes it a very versatile tool for construction and maintenance. In terms of ergonomics, it is surprising how compact and relatively lightweight it is for the power it offers. This facilitates handling in tight spaces and reduces fatigue during long workdays or overhead work. It is a very well-achieved balance between power and maneuverability. At the design level, it also stands out: it has a very attractive visual appearance, with robust finishes that convey quality and durability, something characteristic of the brand. If there were a point to consider, it would be that, like any tool of this type, it is not designed for heavy demolition or extreme continuous use like a dedicated demolition hammer. But within its category, it performs outstandingly. Conclusion: A powerful, versatile, and easy-to-handle rotary hammer, ideal for professional work in concrete and masonry. It stands out for its balance between performance, size, and functionality. Would I buy it again? Without a doubt. It is a reliable and very complete tool that performs perfectly in daily use.

Hot knife through butter.
Another solid tool from Dewalt. Currently drilling 5/8”. It’s like a hot knife through butter. In fact it was so easy that I had to stay focused to make sure I didn’t drill too deep. Never had a rotary hammer work so well. At first I thought that perhaps I shouldn’t spend this much money, but I’m so glad I did.

Worth the price portable drill.
With the correct bits this thing blasts thru concrete. Sds plus bits are the only drawback, I bought and had Hilti bits with 3 sides and this requires the dual slot type. Great portable and effective battery durability. I had many batteries and the tool came without one. It doesn't eat thru the battery though. I put in 22 , 4" inch deep holes on one charge.

Powerful & Efficient Cordless Performer!
DEWALT DCH273B delivers robust power cordlessly. Smooth mode transitions, lightweight design, and pro-level durability make drilling effortless. Lacks battery inclusion, but a must-have for serious tasks. ★★★★☆
