The diamond grinding wheel is useful for grinding concrete, preparing surfaces, and grinding down of patch, self-leveler, and concrete itself. It’s a versatile wheel that fits 7/8 arbor and works on any grinder with at least a 4" capacity. The wheel is available in different colors, but they hold the same capabilities. It's designed with 12 protruding teeth that come in two variants-A and B. A series has smaller diamond segments compared to series B, but there's no clear explanation of the difference in coarseness of the diamond grit. The wheel comes with a half-inch spacer washer to adjust the 7/8 center hole. It's a powerful grinding wheel that leaves lines in the concrete, and users should invest in a shield to minimize the dust produced during the grinding process. Its initial price is economical and outperforms expensive brands from retail stores like Lowe's and Home Depot.
