Difficult-to-cut materials ｜ Carbide grade for Swiss CNC lathes

Superior heat resistance

Stable machining even during high temperature machining conditions

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

Difficult-to-cut materials especially heat resistant alloys and titanium alloys
Front turning / Back turning / Grooving / Cut off

Insert edge comparison after 800 parts: DM4 exhibits excellent wear resistance compared to competitor's insert.
