A multilayered TiN-TiCN-Al2O3-TiN-PVD-coated carbide grade with a tough substrate used for medium machining of all steels and ductile cast irons. Best results when machining dry, but it can be used wet.
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.
Carbide coated grade with Tin-MT TiCN-Al2O3 by CVD. For use on steel, alloyed steel and cast iron. With it's aluminium oxide coating, the grade TIN21 is recommended every time wear characteristics are more important than toughness.
