Set of nine 4-in diamond polishing pads, a matching rubber Velcro backer 5/8-11, a turbo cup, and a pint of densifier/sealer. Each set has grit #30, #50, #100, #200, #400, #800, #1500, #3000, #10000 (or request any custom combination of 9 via Amazon messaging right after ordering, get two additional pads in place of the turbo cup or densifier), a matching rubber Velcro backing pad with 5/8-11 thread, and one pint of two-part densifier/sealer (when reconstitute in water) for surface treatment. This set has all that you need to polish granite or concrete until you get the final shiny mirror finish. Max recommended speed 5000 rpm. DO NOT PUT THESE ON FIXED-SPEED HIGH SPEED GRINDERS!!!
