Description

Goliath UNF Fluteless (Roll Form) HSS-Co5 Bright Tap

  • HSS-Co (Cobalt) Bright Finish UNF Fluteless Machine Tap.
  • HSS Fluteless (Roll Form) Taps.
  • Fluteless taps are also referred to as "Roll Form" or "Thread Flow" taps.
  • Unlike standard taps, fluteless taps create internal threads by pressure deformation, rather than by material removal.
  • As a result, no chips are formed as no material is removed.
  • The thread is formed by the tap in the ductile material creating threads that have a smoother surface and greater tensile strength under dynamic stress than cut threads.
  • It is essential to use a high-quality lubricating fluid when using fluteless taps.
  • Materials with a minimum elongation of 5% and a tensile strength no greater than 1,000 N/mm2 are suitable for thread forming.
  • The thread profile of UNF is the same as for metric threads and is described in the JIS B0206 standard.
  • The thread is described by its major diameter and the number of threads per inch of length (TPI).
  • When used on external threads this series has a greater tensile stress area than coarse threads of the same size.
  • Fine series threads will resist stripping out better than coarse threads in areas where the external and mating internal threads are subjected to loads equal to or greater than the capacity of the screw or bolt.
  • Fine threads are also used where the length of engagement is limited 1-1/4 or where wall thickness demands a fine pitch.
  • Manufactured from HSS this fluteless tap is designed for use in medium tensile materials and is for hand or general machine use.
  • IMPORTANT - Fluteless Taps use different tapping drill sizes than standard taps.
