First Choice: For Finishing Application of Carbon & Alloy Steel, Stainless Steel, Cast Iron, with Small Depth of Cut and Low Feed per Revolution at High SFM (Vc), Brittle! Not for interrupted Cut, Wet 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 turning applications at a high SFM. Use inserts to cut Steel and Stainless Steel. Inserts have hard wear and abrasive resistance substrate with a CVD Al2O3/TiCl2O3/TiCNcoating. Not for interrupted cuts.
