Description: - The Irwin HSS Pro titanium drill bits are primarily designed for drilling metal and harder, tougher alloys.
- Compared to traditional HSS twist drill bits speed can be increased by 40 -60% and feed by 10 -20% without reducing the life time of the drill bit significantly.
- TiN is also a poor conductor of heat, so the heat generated during the drilling process is diverted into the chips and coolant and less into the drill bit.
- These drills have a 135° split point grinding tip which ensures perfect centring and reduced drilling pressure.
- The drill bit body is manufactured from high quality HSS steel coated with 2.5µ Titanium Nitride (TiN), the TiN coating has a hardness of app. 80 HRC and is very resistant to wear.
- TiN has a low coefficient of friction, this results in less power being consumed and less heat generated during the drilling.
