DetailsT-2(large), T-4(medium) & T-3(small) are naturally coated diamonds (not synthetic) with a tapered drum shape for porcelain and metal finishing. These versatile diamonds are manufactured with a unique electrolysis process, not sintered. The initial inner layer of spongenickel acts as a shock absorber for longer lasting use. The outer layer of chrome locks the diamond in place and yields a progressively hardened surface.
