Wet Diamond Polishing set for Concrete

These sets of wet diamond polishing pads were developed especially for polishing concrete countertops. The high abrasion index of concrete causes ordinary diamond polishing pads to wear out faster than necessary. When you use these specially formulated diamond pads to polish your countertop you will immediately see that they outperform diamond pads made for stone. The sets are available in either 4" or 5" and include 1 ea of 50 grit, 100 grit, 200 grit, 400 grit, 800 grit, 1500 grit, and 3000 grit as well as a backer pad to hold them on your grinder. The Backer pad has a 5/8" x 11 arbor. Highest recommended RPM is 5000
