    • Powerful, versatile, and surprisingly compact — professional performance in a manageable format
Style: Rotaty Hammer Only
Review Image by Carlos Garcia
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. ... show more

    • fantastic concrete/cinder block boring/small jackhammer applications.
Style: Rotaty Hammer Only
I debated about buying one of these, or renting one for the day. Turns out that renting one costs half as much as just buying it, and I knew that I'd need it again. You need special bits for it "SDS-plus" but that's okay. Before I used it on my actual project, I practiced on a cyinder block with a 1.5" core saw. HOLY SMOKES! Went through it like butter. I could not believe how fast I got through that cinder block. If you've ever tried putting a masonry drill bit in a regular drill, you will not believe the difference. Turns out that I have some "rotten granite" below ground level that I'm going to need to deal with, so I got some chisels and points for this, and YIKES it just chewed that up like it was sand. There are three modes: hammer drill, hammer only, drill only, easy to select. Be aware that when you're using the hammer it is *LOUD* so wear ear protection. I've been delighted with this rotary hammer. ... show more

    • Powerful and Reliable Rotary Hammer Drill for DIY Projects
Style: Rotaty Hammer Only
The DEWALT 20V MAX SDS Rotary Hammer Drill has become my go-to tool for heavy-duty tasks around the house. As someone who frequently tackles DIY projects, this drill has proven to be both powerful and versatile. I recently used it for drilling into concrete for a new shelving unit in my garage, and the performance was exceptional. The drill handled the tough material with ease, making the job much quicker and less strenuous. The three application modes are a standout feature, allowing for easy switching between drilling, hammer drilling, and chiseling, depending on the task at hand. The cordless design adds a layer of convenience I didn’t realize I was missing. No more being tethered to an outlet or dealing with extension cords. The battery life is impressive, providing ample power for extended use without frequent recharges. One minor downside is that it’s a bit heavier than my previous drill, but the extra weight seems to contribute to its robust build and powerful performance. The ergonomics are well thought out, with a comfortable grip that reduces fatigue during prolonged use. In essence, this DEWALT rotary hammer drill has made my DIY endeavors smoother and more efficient. Its blend of power, versatility, and cordless convenience is perfect for tackling a wide range of home improvement projects. ... show more

    • Drills through concrete and granite with ease

Review Image by J. Knox
Had to anchor a fence post to a boulder on one of my properties that didn't have electricity, and I wasn't going to lug out a generator to power my electric rotary hammer for this one application. The DCH273B made short work of drilling four 10" holes through the boulder and chiseling through an old concrete footer that needed repositioning. Of course it's fairly loud hammering through stone or concrete, so spring for some good hearing protection too. One other detail, make sure you have SDS drill bits handy. Pros: - Versatile, plenty of power to tackle demo or masonry work. - SDS bits are much easier to switch out, and they're tough. Got a chisel bit stuck in some concrete, so I quickly detached and drilled it out with a 5/8"x12" bit. Wasn't worried about hitting or breaking it at all. - Definitely a great addition for any DIYer or professional. I would recommend the dust collector attachment too if you're drilling overhead. Cons: - Heavy, not as lightweight as I would hope. It was noticeably harder to hang it from my tool belt than my normal 20v drill. - Pricier than its cord bound cousin(s). - SDS bit system, glad I got a few SDS drill bits before using it. ... show more

    • Very powerful Hammer Drill
Style: Rotaty Hammer Only
This Rotary Hammer Drill is very powerful for a battery powered device. It is much better and quicker than my other wired hammer drills. It is my first choice when I need to drill multiple or deep holes in concrete. I would definitely recommend it.
