Keep your in-line grinder working efficiently with this BlueFire R823P medium grit cloth portable in-line belt, which is a good choice for all coarse grit stock-removal applications on wood or metal. A durable resin bond provides excellent grain retention, allowing the self-sharpening zirconia alumina abrasive to produce fast and aggressive cuts throughout the belt's life, which is 30-percent longer than competitive zirconia belts. A waterproof X-weight polyester backing provides strength and moderate flexibility ideal for light- to moderate-pressure applications on dry or wet surfaces.
