Features: 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 20 mm mild steel, ten times more holes than split point drills. ; Drills faster lasts longer. ; DRILL BIT SURFACE TREATMENT - Bright Finish Jobber 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. ; Specifications:Diameter3.2 mmFlute Length36 mmOverall Length65 mm
