Review on 💎 Tanzfrosch 2 Pack 4 inch Diamond Cup Grinding Wheel: High Performance Turbo Row Grinding Disc for Concrete, Granite, Marble, Rock, and Cement Polishing by Greg Princeking

This sanding disc arrived quickly, packaged securely in an easy to open plastic case. Keep an eye on the puck, it's tiny and easy to lose. I used this grinding wheel on my DeWalt DWE4011 4 1/2" angle grinder. Installation was easy and straight forward. There are concrete slabs around my garage that stick out in inches and trip over them. I have one such ledge (pictured) inside lightly sanded a minute or two after sanding. Note that this creates a lot of silica dust. Either get someone nearby with a hose and sprayer to dust it off, or get a suitable dust cover and dust collection system. I currently waiting for an adapter that will supposedly allow me to attach the dust cover to my shop vacuum and will update my review if I learn anything new using the dust cover Concrete edges with virtually no noticeable wear on the grinding surface of the disc.
