​CoroMill® 419 is a high-feed milling concept with five edges for roughing to semi-finishing. It offers excellent performance in many material groups and has great possibilities for optimization. The high feed and light-cutting action enable a soft sound, creating an operator-friendly environment.

{{ asset.Description }}




  • High productivity in applications requiring light cutting action
  • Long tool life, especially in difficult-to-machine materials
  • Strong and robust inserts for reliable machining
  • Low power consumption

CoroMill® 419 is now available with steel milling grades GC4330 and GC4340 with Inveio® technology for improved tool life and increased process security.

CoroMill® 419 milling grades GC4330 and GC4340


  • Five cutting edges per insert
  • Wide range of grades and geometries
  • Radius inserts and inserts with parallel land
  • Through coolant on all cutters enables efficient wet machining as well as
    compressed air cooling
  • Reduced axial forces with a 19 degree entering angle and a positive axial inclination angle



Inserts with five cutting edges.


  • High-feed face- and profile milling, including ramping and helical interpolation
  • Suitable for most applications and industry segments
  • Machining of components requiring long overhangs
  • Suitable for low-powered machines and weak fixtures
