Review on KSEIBI 4-1/2 Inch Concrete Grinding Wheel for Angle Grinder | Diamond Cup | Double Row | Polishing & Cleaning Stone, Cement, Marble, Rock, Granite | Surface Grinding (644030) Gold by Louis Abrams

We found a crack in the concrete slab in our living room caused by an earthquake. We discovered this when we took the old carpet to put in the wooden floor. One side of the crack was 1/16 inch higher than the other. I used this diamond grinding wheel to level the top of the panel within a foot of the crack. It worked like a charm on my angle grinder. After I finish the work, there is almost no wear on the grinding wheel. I will be using it again for a crack in my driveway.
