Description

About this item:
  • 31/64″ HSS Long Series Drill – Clam
  • ANSI B94-11
  • 118° chisel point with 30° helix.
  • Chisel point is suitable for general purpose drilling.
  • 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.
