UNC (Unified National Coarse) and UNF (Unified National Fine) thread taps are designed with the proper drill diameter for the size. Single pass drilling and tapping saves time.

  • Drills and taps in a single pass
  • Point is self-centering and eliminates the need for center drilling or center punching
  • Can be used on multi-spindle heads with reversing mechanisms for tapping in most materials

The drilling must be  complete  before the tap engages for the successful application of this tool. Only through holes are recommended optimum setup will drill at the prescribed feed then adjust to the tapping speed. One pass completes drilling and tapping with alignment controlled and cycle time greatly reduced.
