Sandvik Coromant’s GC3330, a wear-resistant grade for cast iron milling, creates opportunities for manufacturers to increase machine utilization as well as remove a lot of metal in a short time without compromising tool life, the company says. Minimizing machining interruptions also enables secure unmanned machining.

GC3330 is equipped with Inveio, the latest technology that uses uni-directional crystal orientation. While the crystal orientation in conventional inserts’ CVD alumina coating normally is random, GC3330 has controlled crystals lined up toward the top surface. This is the secret behind the endurance, predictability and long tool life of GC3330.

The insert grade GC3330 is useful for both dry and wet cast iron milling, from roughing to finishing. Covering a broad application area, Sandvik Coromant’s new grade can be used in any cast iron milling operation for both grey and nodular cast iron materials. GC3330 is available for a variety of milling cutters for face, shoulder, profile, high feed, and parting and grooving milling.
