DM4Difficult-to-cut materials | PVD coated carbide

Excellent heat resistance for finishing

Ideal for difficult materials such as heat resistant alloys and titanium alloys

Eliminates the effects of heat on the insert during high temperature machining
High efficiency and long tool life in high precision finishing of difficult to cut materials


  • A thick TiAlN coating provides heat resistance to extend tool life
  • The combination of heat and wear resistance is ideal for finishing heat resistant alloys and titanium
