4" metal bond sintered diamond grinding wheel/disc with adapter

Metal bond polishing pads with rubber backer pad are applied to quickly remove stock. 

Metal-bond diamond polishing pads are designed to wet-polish all straight or contoured edges for granite, concrete and engineered stones. Metal powders are mixed with resin to provide a tighter bond to diamonds.

They are more aggressive than traditional resin bond pads. While they last longer than resin bond pads on granite, they are the solution for engineered stones.
Application: For grinding of granite, hard marble, concrete and terrazzo.
