This 60-grit cloth file belt uses premium Norton SG ceramic alumina for coarse stock removal with a file belt sander. Its waterproof Y-weight polyester backing helps improve grain adhesion, resist edge fraying, and maintain belt shape for consistent performance. The ceramic alumina grain is designed to cut cooler and last 50% to 200% longer on materials including mild and carbon steels, stainless steel, cobalt, chrome, Inconel, and titanium. A lubricating grinding-aid coating helps reduce heat and loading during work on heat-sensitive materials while supporting burn-free grinding and improved part finish.
