Sandvik Coromant offers insert grades that are designed to boost turning productivity and performance, such as the GC4235 that is said to provide excellent security in both steels and stainless steels, even when working in unstable and demanding conditions. The CC6060 and CC6065 grades of round ceramic inserts achieve four to six times the cutting speed of conventional carbide inserts in medium to roughing operations. The CB7025 is said to optimize cutting results in light to heavy interrupted cuts of case-hardened steel.
