Sandvik Coromant Inc.’s GC4335 insert grade is for the turning of steels where unstable conditions or vibration issues prevail. The insert grade is designed to bring about secure and predictable machining as well as shorter cycle times and better machine utilization through reduced stoppages and longer insert life. 

The insert grade features Inveio coating technology for thermal protection and offers steel turning endurance through improved edge-line security in comparison with the previous generation grade, along with greater resistance to flank wear, plastic deformation, and crater wear, the company says. Typical components include tubes, valves, crankshafts, differential housings, flanges, and rings to list a few.

According to the company, a substrate that is balanced between reliable toughness and resistance to plastic deformation and an alumina coating deliver efficient heat transfer from the cutting zone to act as a heat barrier. The columnar MT-TiCN inner coating also offers improved resistance against abrasive wear and a yellow TiN coating on the insert flank allows for wear detection.
