Rubberized abrasives for light deburring, smoothing and polishing. Made from a special formula, combining pure silicon carbide granules with a special oil-resistant rubber bond. They deliver cushion-action performance in a variety of applications on a wide range of materials such as metal, plastic, glass and porcelain. Cratex abrasives can be shaped with conventional wheel dressers and do not harden or soften during use or storage.

Cratex rubberized abrasive wheels are made in four standard grit textures or compositions which differ in accordance with the mesh size of the silicon carbide abrasive grain used: Coarse (Green), Medium (Dark Brown), Fine (Reddish Brown), and Extra Fine (Grey Green).
