Designed for cast iron milling, Sandvik Coromant’s wear-resistant GC3330 insert grade features the company’s Inveio coating, which uses uni-directional crystal orientation for greater endurance, predictability and tool life. (While the crystal orientation in conventional inserts’ CVD alumina coating normally is random, GC3330 has controlled crystals lined up towards the top surface.)

According to Sandvik, the grade’s consistent performance allows manufacturers to increase machine utilization as well as remove a lot of metal in a short time without compromising tool life. Minimizing machining interruptions also enables secure unmanned machining, the company says.

The GC3330 insert grade is suitable for both dry and wet cast iron milling, from roughing to finishing. It can be used in any cast iron milling operation for both grey and nodular cast iron materials, and is available for a variety of milling cutters for face-, shoulder-, profile-, high-feed-, and parting and grooving milling.
