About Bordo Metric Delta Point M2 HSS Jobber Drill DIN 338
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.
