Quick-Change Sanding Disc: TR, 1-1/2", Ceramic, 60 Grit, YF Wt Polyester, 984F, 50 PK

Cool-cutting sanding discs optimized for use on all metals have an open-coat ceramic abrasive. An additional coating minimizes surface temperatures for heat-sensitive alloys. Cool-cutting ceramic is coated to prevent loading and keep surface temperatures down when working with heat-sensitive materials such as stainless steel and aluminum. Ceramic self-sharpens faster than other abrasives to remove material faster. Open-coat abrasives have grit on about 50% of the surface leaving space between the abrasive grains to prevent swarf from clogging the surface which keeps the workpiece cooler. The flexible, tear-resistant cloth backing conforms to contours and is more durable and tear resistant than paper.
