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 Drew Poulin

This saved me several days of work. I'm renovating my kitchen and doing the floors right now. Since I messed up the install the first time I had to remove the entire tile. But I'm cheap and I want to reuse them if possible. This means that I have to remove the grout from the back of all of them, which is not an easy task. I used serrated lock washers on an angle grinder. It took forever and when I was done about 3-5 before I had to change a wheel. I even ended up burning out the angle grinder motor because it took so long and there was so much dust. Be careful if you're dumb enough to use it like I did - it's not subtle. If you aggressively chase a tile, you won't have a single tile left. Start small in the corner, get your bearings, and know exactly how much grinding you need to do. But it works great! On weekends I did what used to take weeks and a lot more money.
