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.
MIRACLE SIGMA PVD coating technology that utilizes accumulated layers of Al-Ti-Cr-N based PVD coatings to provide extremely high levels of wear, heat and welding resistance that was not possible with older coatings. Multi-layering of the new coating helps prevent any crack propagation through to the carbide substrate, this in turn dramatically improves the overall fracture resistance of the insert.
