Description

About this item:
  • 6.90mm Delta Point Bright HSS Twist
  • Bordo Metric Delta Point M2-HSS Twist Drills.
  • DIN338
  • 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.
