SANDVIK COROMANT introduced a new indexable milling grade - GC1250 - for titanium alloy machining, a materials that combines its patented EthaCore^™ carbide technology with a Zertivo^® nano-multilayer physical vapor deposition (PVD) coating to improve resilience, tool life, and process security, while reducing the carbon footprint of tooling.

Titanium’s poor thermal conductivity concentrates extreme heat at the cutting edge, increasing the risk of rapid wear, chipping and unexpected insert failure. GC1250 addresses these challenges with a new grade architecture.

The product value is built around three pillars: innovation, performance and sustainability. Its resilient substrate is designed to adapt to changing thermal and mechanical loads, helping deliver more predictable tool life, fewer unexpected breakages and reduced production downtime.

“GC1250 sets a new benchmark for resilience and predictable performance in titanium milling,” stated global product manager Wayne Mason. “By reducing unexpected insert failures and interruptions, this grade can help customers increase machine utilization and achieve more cost-efficient machining.”

Grade GC1250 also helps customers work toward their sustainability targets. EthaCore^™ contributes to a substantially lower product carbon footprint than leading competitor grades that use ruthenium-based carbide for titanium machining.

“Performance and sustainability need to advance together,” Mason said. “GC1250 gives manufacturers a solution that supports secure, productive titanium machining while helping reduce the carbon footprint associated with their tooling.”

Grade GC1250 is optimized for roughing to semi-finishing of titanium alloys. It’s designed for wet machining and is available across a broad range of Sandvik Coromant’s CoroMill^® indexable shoulder, face, groove, high-feed and profile milling concepts.

The introduction of grade GC1250 also completes the company’s 1200 series of grades, creating a comprehensive portfolio covering all major workpiece material groups. Customers can now access the latest substrate and coating technologies across a wide range of machining applications.
