Exactly what I needed

Exactly what I needed
We purchased this Dewalt angle grinder to cut thin brick for a fireplace. We purchased from the Dewalt line since we already have many of their battery operated tools, and therefore have the compatible batteries (which are not included with the tool). This helped us execute the job and make clean, precise cuts. It’s very easy to operate and has excellent safety features. This will be a great, versatile tool to add to our repertoire. The only downside is that it eats through our 1.3 Ah 20V max batteries very quickly. Not that big of a downside if you’re okay changing the battery frequently or already have higher Ah batteries on hand. We will be considering buying larger capacity batteries in the future to remedy this.
