Unique design increases productivity through longer tool life


  • Necked design enhances flow of cutting fluid to cutting teeth & reduces surface contact between the tool & workpiece for more efficient threading.
  • Special ZELX tool geometry creates less torque, better removal of chips & runs cooler.


  • For stainless steels, alloy steels & ductile irons.
  • Designed for difficult jobs including the stainless steel family of materials as well as alloys steels, high carbon steel & ductile irons.
  • Suitable for tapping 303, 304, 410 stainless steel & 8740 (SNCM240).
  • The modified bottom chamfer makes them ideally suited to blind hole tapping.


  • 2-1/2 to 3-1/2 threads chamfered.
  • Black oxide surface treated.
  • Helix angle 45°.
  • Suitable for UNJ Aerospace internal threading applications.
