Designed for series 300 stainless steel, except for 303


  • Much tougher than cobalt steel.
  • Thin web design penetrates work hardening stainless steel fast enough to continually cut beneath the chip which is hardening from deformation.
  • 135° split point design stops drill walking, holds tighter hole size and takes a smaller chip resulting in less heat.
  • Low temperature stress relief improves lubricity and toughness.


  • Outperforms cobalt drills in work hardening stainless steel applications.


  • Manufactured to NAS 907B specification.
  • Nito-carburized flute has an increased rockwell hardness.
  • Rich amber color.
