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 Alvaro Delic

I have used this on a 4.5 inch angle grinder to sand down stains on concrete floors and log wall paneling. Robust and very aggressive tool for very fast work. Due to the high levels of dust, dirt and noise, the user needs a high-quality respirator as well as hearing and eye protection. I suggest a high volume dust extractor or equivalent ventilation if used inside the structure. Another option is wet sanding with an air sander. Aggressive bite on this disc, variable speed grinder helps control work. DO NOT use on grinders without OEM protection.
