Rated 5 out of 5 by from A product that does its job ! installing retaining wall blocks, sometimes have to grind some off to fit. worked really well for me, bought an extra one for future projects.

Rated 3 out of 5 by from Should be called concrete "polishing" wheel. These should be called "polishing" rather than "grinding" wheels (at least for concrete). They do not aggressively remove material. I was hoping to remove a depth of about 1/4 to 1/2 inch of roughly 4 square feet of patio surface which had been poorly laid and does not drain properly. In all fairness, I am used to metal grinding; so that is my only basis for comparison. The price was very low, too, and they may suit other needs just fine. The HD was out of stock on 7" wheels -- which may work better.
