    Product Description

  • Cobalt jobber drills offer increased hardness, toughness and better wear resistance compared to regular HSS
  • Bright surface finish provides a polished finish and prevents chip building, galling and welding on a workpiece
  • 135° Degree split point (self-centering) which eliminates "walking" and reduces the thrust force needed
  • Parabolic flute design facilitates effective chip evacuation for deep hole drilling
  • Suitable for a wide range of ferrous and non-ferrous materials
