## Description

From the manufacturer

Review: Do the job - 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
Review: Compacto, ligero y fuerte. - 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.

**Q: Do u sell a case for this ?**
A: No

**Q: I need to drill 1/2 inch holes in granite rocks maybe 4-5 inches deep, will this do the job or do I need a bigger unit ?**
A: Yes this should handle that, I use it to drill 1/2 holes six inches deep in concrete regularly so granite should be fine. Remember the bits are SDS slotted drill system no chuck key required also a bonus.

2 modes only.

### ⭐⭐⭐⭐⭐ Great little hammer drill
*by L***. on 4 April 2022*

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.
