The diamond in these sanding blocks ensures a perfectly finished result. Ideal for working on corners, edges, and straight and/or slightly curved surfaces. InterDynamics diamond hand sanding blocks are suitable for dry and wet use and for natural stone, ceramic tiles, granite, marble, concrete, polyester, and plastics. Because the sanding blocks are coated with diamond powder, they have a longer lifespan.

Available individually and in a complete set in four different grits: 60, 120, 200, and 400.
