The new insert grade GC3330 is an excellent 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.
Having already introduced the game-changing grade GC4325 for steel turning, Sandvik Coromant now introduces GC3330, a wear-resistant first-choice grade for cast iron milling. The insert grade GC3330 for cast iron milling will be available from March.
With predictable performance becoming increasingly important in many machining processes, GC3330 meets the needs of today’s manufacturing. The consistent performance of GC3330 creates opportunities for manufacturers to increase machine utilisation as well as remove a lot of metal in a short time without compromising tool life. Reduced machining interruptions also enable secure unmanned machining.
GC3330 is equipped with Inveio, which 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 to provide additional endurance, predictability and long tool life to the GC3330.
