TiN coating is a very hard, gold coloured surface coating a few microns thick which is applied by means of a complex process, called Physical Vapour Deposition (PVD), by advanced modern equipment.
The coating is non-metallic and therefore reduces cold welding. In certain applications increased speed and feed rates can be achieved because of:
(a) The hardness of the coating.
(b) The reduction in cutting force required due to a decrease in friction between the tool and the workpiece.
Tool performance will deteriorate after re-sharpening.
