Super high speed milling
- Newly developed ultra aluminum rich Al-Ti-Cr multi-layered “GS Hard Coat” allows super high speed milling up to 800m/min.
High rigidity
- Unique geometry improves chip removal and tool rigidity.
Long tool life
- Ultra micro grain low-cobalt carbide with high hardness improves tool material strength and curtails micro-plastic deformation that can occur at very high speeds. The result is better durability.
GS Hard Coat
Top layered film consists of newly developed ultra aluminum rich Al-Ti-Cr coating, with 3 times better oxidation resistance at 1,100 deg Centigrade.
