All About 118° Split Point (crankshaft point)

  • The split point is self-centering and reduces the need for end thrust.
  • Friction at the 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 that are wide and thin.

All About Drill Bit Surface Treatment

  • Black Finish Jobber 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.
