- Delta Point drills have a multi-faceted cutting tip.
- Rather than try and modify existing point types, or tweak the grind angles, Delta Point tip design required a revolutionary re-think of drill tip function.
- The overall length of the cutting edge significantly exceeds that of conventional drills.
- This means more edge doing the cutting and the results are simply extraordinary.
- Drilling times for a range of split point and Delta Point drills consistently showed that Delta Point bits were twice as fast in mild steel.
- During independent lifetime testing Delta point drill bits averaged 609 holes in 20mm mild steel, ten times more holes than split point drills.
- DRILLS FASTER LASTS LONGER.
- Bright Finish Twist Drills have no surface treatment and are supplied in the as-ground condition. These tools are suitable for general purpose use, particularly for non-ferrous applications.
