New indexable milling grade for nodular cast iron

Sandvik Cormorant has introduced GC1220, a new indexable milling insert grade for nodular cast iron. According to a statement from the company, the new grade is resistant to abrasion and thermal cracking in wet or dry conditions.

The new grade also features a physical vapor deposition coating for wear resistance, courtesy of the company’s Zertivo-brand coating process. The coating consists of layers of TiAIN and TiSiN and reportedly allows a synergy of wear resistance without compromising edge line toughness.

Sandvik Cormorant’s website notes the GC1220 grade is designed for light roughing to finishing operations for wet or dry machining, and is suitable for nodular cast iron or small diameter cutters.

Wayne Mason, a global product application manager for grades at Sandvik Cormorant, said the new product builds on the company’s GC1230 steel milling grade.

“GC1220 has a groundbreaking coating innovation delivering exceptional performance with security, predictability and sustainability,” Mayson said. “With its advanced PVD coating and robust performance in demanding conditions, I am confident that GC1220 will define a new level of performance for cast iron machining.”
