Review on Diamond X Teeth Porcelain Granite Concrete by Robert Pearson

Good basic diamond blade for angle grinders. I use this with a 20v DeWalt grinder and was able to cut through concrete easily. The blade is designed for up to 13,000 rpm and still cuts well after a while. I like the segmented design and it seems to work really well on concrete. I have not tried this blade on brick or tile, I believe it will work fine. Overall I am happy with this blade for small cuts in concrete. I wasn't expecting it to cut so easily, it's better than other concrete cutting blades I've used. Good price, 3 piece set is even better if you cut a lot of concrete. For a small to medium project, one blade should do the trick, but it depends on how much you're going to be cutting. I've been cutting with water running down concrete, I think it helps keep heat down and reduces friction when cutting.
