About this item:
  • 12 Piece HSS-Co5 Cobalt Drill Refill Set
  • Bordo Metric Cobalt Tough HSS-Co5 Twist Drills.
  • DIN338
  • 135º Split Point (crankshaft point).
  • Split point is self centering and the short distance from the drill axis to the outer corners results in faster penetration, reducing the need for end thrust.
  • The 135º point should be used to cut harder steel materials especially in deep hole applications.
  • In these situations it will produce thicker chips minimising work hardening of the cavity.
  • Faster penetration reduces abrasion and friction along the cutting edges.
  • Cobalt HSS Twist drills are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
  • Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.
