Norseman 221-PT:
  • Parabolic flute geometry eliminates pecking (drill removal) when drilling deep holes
  • Split point design and heavy duty design provide superior performance by permitting higher feed rates and continuous drilling of deep holes
  • TiN coating provides superior wear resistance and up to a 500% increase in machining speeds
  • 135° modified notch point is self-centering, provides greater stability, prevents "walking" and lessens work hardening.
