Sterling Edge Backdraft inserts are the standard bearer in profile milling on draft walls where the application requires chip clearance. These inserts are drafted 3deg at the bottom and on the side walls designed to provide effective Z-level and plunge milling without chatter.
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.
Used in hard machining applications of 50-70 RC for abrasive materials where heat is an issue.
