Solid carbide drills surface finishing by coatings

Therefore the nenok solid carbide drills are delivered with an especially powerful TiN coating or FIRE multi-layer coating.

TiN coating

  • Titanium nitride coating is a thin wear-protection coating of golden yellow colour
  • The single-layer titanium nitride coating is applied using the PVD method
  • The hardness is 2300 HV
  • The coating is suitable for a maximum application temperature of < 600 °C

 

FIRE coating

  • The FIRE coating is a TiAlN/TiN multilayer coating in violet colour
  • The hardness is 3300 HV
  • The coating is suitable for a maximum application temperature of < 800 °C
