DT4/DM4Difficult-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

  • Thick 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

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