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.
A grade with high edge strength and suitable for roughing and semi-finishing. Can be used on cast steel, carbon steel, alloy steels, hardened steels as well as 400 series stainless steel. Also has the added edge strength and shock resistance where most grades fail. This strong grade can be run in the 350 to 1,000 SFM range.
