High-speed milling cutter for cutting graphite

The graphite electrodes for producing small and deep contours in injection moulds are becoming always more complex and more comprehensive
The electrodes are milled from a never-ending source, which requires top cutting performance. Due to the abrasiveness of graphite, milling cutters with special diamond coatings are needed to ensure long tool lives. The DIA coating was designed and developed to meet this requirement.


  • Increase in productivity due to HSC application
  • Special diamond coating for maximum tool life in graphite
  • Tools with minute diameters, specifically for machining lattice electrodes
  • Due to neck-free finish, projection lengths of up to 20 x d1 are possible
