Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites. The cobalt content could vary from 5% to 23% base on application. 8% to 12% are the most common for cutting tools. Ruthenium is used to replace cobalt as a perfered binder for the best cutting performance.
Medium to heavy roughing over a variety of materials including cast steels, carbon steel, alloy and hardened steels, and 400 series stainless steel. Excellent life at speeds of 325 to 6500 SFM with greater resistance to edge wear. Also added strength provided by a special sinter-hip enhancement.
