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.

1. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.
2. Universal 135° point shape for drilling a wide selection of materials.
3. Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.
4. Ground flutes provide fast chip removal to maximize accuracy and efficiency along the full working surface of the bit.
5. Special multi-cut geometry with ply-cutting and lower friction to reach better performance of endurance and removal of chips. So its life is lengthened. It is stable made and can cut with high speed, and make the surface of materials smooth. It has exact diameter and can use after regrinding.
