Metal bond diamond flexible polishing pads are specially designed for granite polishing, concrete polishing and engineered stone polishing. They are widely applied to wet polish curved edges, straight edges and flat surfaces. The special made metal-and-resin mixed bond helps to reduce abrasion of the pads and increase the polishing efficiency greatly. They are much more aggressive and long lasting than the conventional ones. 3", 4" and 5" is available. The straight or curved slots on the surface make the pads extremely flexible. #50, #100, #200 comes in metal-bond, others in resin bond.
