About this item:
  • 29/64" Black HSS Twist
  • 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.
