QM3Carbon steel / Alloy steel machining | Carbide grade for Swiss CNC lathes

Amazing wear resistance, fracture resistance for wide speed range. Stable machining in demanding applications.

Long tool life and stable machining of carbon steel (like S45C) and alloy steel

Excellent toughness and stability


  • Superior fracture resistance due to the tough base material and a special TiCN coating
  • Resists wear even in low speed range
  • Stable performance through interruptions

Tooling application

For Carbon steel and Alloy steel
Front turning / Back turning / Grooving / ID boring / Threading / Cut off
