Difficult-to-cut materials | Carbide grade for Swiss CNC lathes
Superior heat resistance
Ideal for difficult materials such as heat resistant alloys and titanium alloys
Stable machining even during high temperature machining conditions
Features
- TiAlN layer protect against insert deterioration from excessive heat
- DT4 has a thin coating. Insert sharpness benefits machining small diameter parts
- DM4 has a thick coating. Its heat and wear resistance suite it well for high load grooving and cut-off operations.
Tooling application
