You’ll need the crack-chasing blade for your angle grinder. The best 4.5 inch blade is the Benchmark Abrasives 4.5 in. Crack Chaser Diamond Blade. This is the blade that cuts concrete like butter. If you own a 4 in. angle grinder already, then get the EDiamondTools 4 in. Crack Chaser Blade. Customers report that it barely shows signs of use after cutting hundreds of feet of concrete.

Updated to say; I just ordered 3 more of these grinders. I LOVE the one touch guard!!!! You just bump it against the welding table to rotate it to any position you need….I’m quickly replacing all my grinders with these Dewalts….I like to keep about 10 grinders plugged in with different wheels and discs ready to grab, and these paddle switch high amp Dewalts have proven the best bang for the buck yet over all the others. — Amazon reviewer
