  Delta Point Bright Finish HSS

  BORDO Delta Point Bright Finish HSS Metric

  • 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.

  Black Finish HSS

  BORDO Black Finish HSS Jobber Drill Fractional

  • Bordo Black Knight M2-HSS Twist Drills.
  • ANSI B94-11
  • 118° Split Point (crankshaft point)
  • Split point is self centering and reduces the need for end thrust.
  • Friction at workpiece is reduced.
  • 118° point angles are ideal for use in materials such as mild steel and cast iron.
  • The 118° point creates easily controlled chips which are wide and thin.
  • Black Finish Twist Drills (also called blue finish) achieve their distinctive colour by steam tempering, a thermal process resulting in a porous tool coating.
  • This surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding. The result is increased tool life.
  • Black finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation.

  Colour Band

  BORDO Red Band HSS-Co TiAlN Tough Treatable Steel Drilling

  • Bordo Metric Red Band HSS-Co TiAlN Coated Twist Drills for Tough Treatable Steel.
  • DIN338
  • 130° UX point with two helical parabolic flutes with 33 degrees of helix angle.
  • The mechanical properties of materials are influenced diversely by the addition of alloying elements and heat treatment processes, resulting in some high-strength, quenched and tempered steels or hardened steels.
  • This range has its own unique set of machining requirements which are satisfied by the Red Band – Tough Treatable Steel – Series.
  • TiAlN coating increases tool surface hardness to 87Rc.
  • For machining materials with Hardness < 470 HB : Tensile Strength <1500 N/mm2.
