Solid carbide drills surface
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
