Description
Features:
- Drill bit surface treatment gold finish (TiN) (Titanium Nitride)
- A very hard gold coloured surface finish a few microns thick is achieved by Physical Vapour Deposition (PVD). As with all surface coated tools, performance will deteriorate after resharpening.
- The coating helps to dissipate heat and reduces friction and cold welding.
- Higher speed and feed rates can be achieved and tool life is greatly increased.
