Grade GC3330 leads the way for cast iron milling


Sandvik Coromant takes cast iron milling to a new level on March 3rd when the insert grade GC3330 is introduced.

Grade GC3330 leads the way for cast iron millingCast iron milling is the next machining area covered by the new grades with Inveio™ from Sandvik Coromant. Having already introduced the game-changing grade GC4325 for steel turning, the innovative cutting tools supplier now introduces GC3330, a wear-resistant first choice grade for cast iron milling.

With predictable performance becoming increasingly important in many machining processes, GC3330 is meeting the needs of today’s manufacturing. The consistent performance of GC3330 creates opportunities for manufacturers to increase machine utilization as well as removing a lot of metal in a short time without compromising tool life. Minimizing machining interruptions also enables secure unmanned machining.

Inveio – the innovation behind

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

Application area

The new insert grade GC3330 is the first choice 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.
