  • Usable on every vertical drilling machine or machines with rotating non-reversing spindles for both high production and precision tapping.


  • Right or left hand tapping without modification of blind or through holes.
  • Complete protection against tap breakage ensured by an ultra-sensitive and smooth operating ball clutch.
  • Forward and reverse ball drive design transmits rotational power to the tap to obtain significant reduction in friction during operation.
  • Axial float ensures smooth tapping and better thread profile.
  • Cushioned drive eliminates cross threading and ensures gauge perfect thread.
  • Self-feed ensures gauge perfect thread.
