These revolutionary grinding and glazing wheels combine the sharpness of diamonds in a razor-thin rubber disk for maximum flexibility. Each rubber disk is impregnated with high-density diamond particles to produce a superior polishing surface and ultra-sharp razor-thin cutting edge. Three color-coded formulations, one for each need. The Red Wheel is used for a coarse polish; the Blue Wheel a medium polish; and the Yellow Wheel for a fine high-gloss shine. The wheels are durable and long-lasting and are excellent for complete control of texture, luster, and glaze finish without messy pastes, cracked porcelains or re-firing. These wheels can also finish margins of all ceramic restorations without causing vibrations.
