Dewalt DCH172B 20V MAX ATOMIC Brushless Lithium-Ion 5/8 in. Cordless SDS PLUS Rotary Hammer (Tool Only)

Excelente máquina, con suficiente fuerza para trabajos cotidianos, muy compacto y ligero. Con el uso adecuado tendré una máquina por mucho tiempo, siempre respetando sus ciclos de trabajo. No lo he llevado al límite pero con el uso he descubierto que se proteje y se detiene. Lo he utilizado con una batería 4aH y esa me finciona perfecto, tengo mas pequeña y parece que no abastece suficiente en marchas forzadas. Esperemos que con un uso moderado siga funcionando como hasta ahora.

I remember being excited about an $1800.00 hilti cordless hammer drill 20 years ago. Could only do 30 holes 1/4” diameter and 1-1/2” deep. I have 4 Milwaukee hammer drills and 4 DCH273B dewalt hammer drills, and I thought they were good. This little DCH172B is the bomb! The best I have for overhead work, really light, doesn’t hit hard but does it vibrate. The DCH273B will shatter finger nail size concrete in your face as it drives a 1/4” bit in, but the DCH172B rarely shatters the concrete while driving in the drill bit. It’s impressive. BTW that Hilti hammer drill was total garbage, weighed a ton and was just huge.

Dwalt is in the top 3 so no doubt that it's best of the best but i wish i could try it with bigger battery because i didn't feel the power with my 2 Ah battery

Let's not mince words: the DeWalt 20V MAX SDS+ Rotary Hammer (tool-only or kit) is a game-changer. I have used standard hammer drills for years, thinking they were "good enough." This tool proves that "good enough" is simply wasting time and effort. This rotary hammer is professional-grade power packed into a cordless form factor that is just phenomenal . Proof of Performance: It Kicked Ass on Brick I recently took on a big project building a porch and needed to anchor heavy support brackets directly into an old, tough brick foundation. This is usually a painstaking, vibration-heavy job. With the DeWalt SDS+ and a quality masonry bit, the process was lightning fast. I'm talking drilling perfect, clean holes into solid brick like it was soft wood. The entire mounting process, which I budgeted half a day for, was finished in less than an hour. The power delivery is controlled, yet relentless—it just chews through concrete, mortar, and brick effortlessly. 100% Worth the Investment Since that porch project, I've found a dozen reasons to pull this tool out. From setting concrete anchors for a new fence post to chipping away tile adhesive (using the chipping function), this tool handles it all. The cordless mobility is essential for jobsite use, and the vibration dampening is surprisingly good, meaning you can run it longer without hand fatigue. If you are a DIYer tackling serious masonry, or a professional looking for unmatched cordless drilling efficiency, this tool is 100% worth the price of admission. It performs well above its weight class and will make your toughest tasks feel ridiculously simple. Don't hesitate—buy this hammer.
