  • Item Features
  • General purpose geometry for drilling in a wide range of operating conditions and materials
  • Taper length provides longer overall length and flute length for deeper drilling
  • Peck cycles may be appropriate for deep hole drilling
  • Black oxide finish provides increased wear resistance and added lubricity
  • High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and non-ferrous materials
  • Oxide prevents chip building, galling and welding on the workpiece
  • Spiral flutes are constructed with a higher flute angle to remove chips more easily
