Review on ⚙️ APLUS 5-Inch Turbo Diamond Cup Grinding Wheel, Grinding Disc for Concrete, Granite, Stone, Marble, and More by Brian Nicholas

Works great in my Ryobi grinder with no attachments, washers, adapters etc. Thing MELTS concrete, no need to move it at an angle as with metal it goes flat and smooth , and the concrete is easy to remove. I used this to sand down a 20'x16' magazine for an epoxy floor installation. It's ROUND! As others have said, wear a mask, have a fan and best of all hook up to a store bought vacuum. Creates a TON of DUST! Great product, don't know why others are charging $40+ if this works great save your $. Enjoy it and like it 👍
