Hatho® has raised the standard of excellence for rotating polishing instruments with their unsurpassed German quality and patented features. Manufactured by 3M™, this disc offers a unique, three-dimensional abrasive/flexible bristle design that provides a uniform finish. Ideal for heavy cleaning (coarse), removing light oxide (medium), prepolishing, semifinishing, blending, texturizing, and polishing (fine). Provides the convenience of a precharged abrasive but does not generate the heat associated with rubber wheels. 10,000 rpm. Recommended: 4 discs mounted together.
