First Choice: For Finishing Application of Cast Iron, Hardened Steel, Non-Ferrous, with Small Depth of Cut and Low Feed per Revolution at High SFM (Vc), Brittle! Not for interrupted Cut, Wet/Dry Working Condition
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.
For finishing to roughing applications at a high SFM. Use inserts to cut Gray Iron, Modular Cast Iron and Ductile Iron. Inserts have a high wear resistant substrate and cutting edge with a CVD TiN/TICl2TiO5/Al2O3 coating.
