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
