    Product Description

  • HSS
  • Black oxide finish for increased wear resistance and added lubricity
  • 135° Degree split point for fast penetration and accurate starting (self-centering) which eliminates "walking" and reduces the thrust force needed
  • Longer overall length but shorter flute length for maximum rigidity
  • Used where extra reach is required or for drilling holes in hard-to-reach places
  • Ideal for a wide range of materials
