7" Diamond Cup Grinding Wheels for Concrete 24 Double Row ...
I bought this grinding wheel for two purposes: 1.) To smooth some concrete patch work; 2.) To remove cement residue from removal of quarry tiles on the front and back porch. So far its done an excellent job on both projects. I use it with a Ryobi 7 inch angle grinder and there weren't any problems mating the grinding wheel to the grinder.
