## Description

National Diamond SB3U Unslotted Diamond Plated Saw Blade 3" x 3/8", 40 GritPLATED PRODUCTS Plated products are usually a single layer of diamonds highly concentrated and held on by a tough, durable nickel alloy. This high concentration, usually about 140-150, enables plated products to remain their original shape and dimension throughout their working life. Unlike the metal or resin bond impregnated products where the diamond particles are buried in the bond, the plated product allows the diamond particles to protrude from the surface and gives a freer, faster cutting action with minimum heat generation. MATERIALSDiamond Plated products can be used successfully on the following materials:Glass Laminated, Cermets, Melamine, Brake Linings, Epoxy, Taped Graphite,Glass Bonded Mica, Barium Titanate, Clutch Linings, Onyx, Beryllium u m Oxide, Transmission Bands, Marble, Porcelain, Alumina, Quartz, Silicone, Stone, Green Carbide, Carbide, Ferrites, Micarta, Refrasil, Astralite, Ceramics, Pure Glass, Refractory, Graphite, Carbon, Asbestos, Fiberglass and Polyesters.
