Sanding Sheets for Masonry, Ceramics,
and Composites—Use with Sheet Sanders

Sharper than silicon carbide and harder than ceramic alumina, the diamond abrasive on these sheets is ideal for sanding concrete, fiberglass, and other tough materials. They also have a cloth backing that’s flexible and difficult to tear. Cut to convenient sizes and shapes, they fit most sheet sanders.

Sanding Belts for Masonry, Ceramics, and Composites

For sanding hard, nonmetal surfaces, these belts are diamonds in the rough. Their diamond abrasive is the hardest and most durable we offer—it's sharp like silicon carbide and tough like ceramic alumina. That makes them a good choice for shaping and smoothing a variety of surfaces from concrete blocks and fiberglass panels to ceramic tiles and graphite molds. These belts resist breaking down and softening from water and cuttings fluids. A cloth backing makes them flexible and resistant to tearing.

Diamond Lapping Film

Sheets

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping grains. Lap without the mess of pastes and slurries—abrasive is embedded in the surface of this waterproof film. Grit and microns are approximate.
