ZIRCONIA ALUMINA: Our zirconia sanding belts are self-sharpening as they cut and work best under high pressure to expose newer sharper edges. VERSATILITY: The combination of grit, abrasive, y-weight backing and closed coat design makes this sander belt perfect for applications such as de-burring, shaping, weld removal, finishing and tool and can be even be used as a knife blade sharpener.
