h1. Uncoated Grades h3. C1 * Is a strong micrograin carbide which resists chipping, breaking, and edge build-up. Great for roughing at high feed rates on interrupted cuts. Use for titanium, high temperature alloys, inconel, and hastalloy. h3. C2 * Is a relatively fine grain grade on a WC-CO base. It has very good toughness and good rake angle resistance to abrasive wear. Applications include stainless steels, cast irons, non-ferrous metals, and most high temperature alloys. h3. C7 * Finish and light roughing non-coated grade for steel and steel castings. Performs best in favorable conditions. High speeds and moderate feeds.<br/><br/> h1. Titanium Coated Grades h3. TN * Discontinued, replaced by TT. h3. TT * Is a very tough grade with a triple coating of Tin, TiC, and TiN. It is a good grade for roughing and finishing in less than ideal conditions. Used in machining steels and stainless steels at low speeds. h3. TE * Is a carbide grade with a PVD coating. It is used for machining aerospace materials, high temperature alloys, and stainless steels. h3. TR * Is a PVD coated micrograin carbide. Performs well in alloy steels, nickel-based materials, and heat-treated materials up to RC 40. h3. SN * Delivers outstanding performance in moderate-roughing to semi-finishing operations, especially in interrupted cuts. An advanced multi-layer coating (TiCN/AI2 O3 /TiN), applied over a cobalt enriched substrate, gives SN a near optimum balance of toughness, surface lubricity, and resistance to metal build-up to yield excellent wear resistance throughout its application range. h3. VN * Is a micro-grained grade with an excellent balance of toughness and wear resistance. Coated with PVD TiN for improved lubricity and wear resistance with up-sharp cutting edges, VN excels in light roughing to high-speed finishing of high-temperature alloys, stainless steels, cast iron, aluminum, and non-ferrous materials.<br/><br/> h1. Cermet Grades h3. CT * Is a cermet grade of TiC and TiN particles in a nickel cobalt binder. It is used in finishing steels at high cutting speeds. h3. CM * Is a cermet grade. It is slightly less hard than CT and can be used in less favorable conditions. h3. CR * Is a titanium nitride cermet which combines toughness and edge wear. Use on steels up to RC 35. h3. CC * A titanium coated cermet for better wear resistance.<br/><br/> h1. Aluminum Oxide Coated Grades h3. AL * Is an AL2 O3 coated insert. Its application is machining cast iron and steels at moderately high speeds. 2007-01-17T12:17:23+00:00 false false 155 true false Uncoated Grades C1 Is a strong micrograin carbide which resists chipping, breaking, and edge build-up.
