Solid carbide drills surface finishing by coating
Solid carbide drills without surface finishing have quite good performance characteristics, which can be remarkably improved by providing them with a surface finishing by coating.
Therefore the nenok solid carbide drills are delivered with a especially powerful TiN coating or FIRE multi-layer coating.
Titanium nitride coating is a thin wear-protection coating of golden yellow colour.
The single-layer titanium nitride coating is applied by PVD method.
The hardness is of 2300 HV.
The coating is suitable for an application temperature up to max. 600° C.
The coating is suitable for an application temperature up to max. 800° C.
