Review on Sunjoyco 4-Inch Diamond Cup Grinding Wheel - 12-Segment Heavy Duty Turbo Row Disc For Concrete, Granite, Stone, Marble, Masonry And More by Jim Bethea

Had to grind an uneven concrete step near the main door- to avoid trips/falls.This worked perfectly and was really good-aggressive in removing the material.I used the DeWalt grinding wheel before that and found it very time consuming.This reduced the work in half.Used it on a 5 inch Metabo angle grinder.good tool to have in the kit.
