• 1/8″ x 28 BSPT HSS Tap Set – Goliath
  • HSS Bright Finish BSPT Hand and Machine Tap Set.
  • Pipe taps are much shorter than a similar size of regular hand tap, but the design features are the same.
  • Goliath HSS taps provide a high hardness to toughness ratio, compressive and tensile strength, good abrasion resistance and resistance to micro-chipping, ensuring a long tool life.
  • Tapered Pipe Taps are used for tapered threading by hand or machine.
  • British Standard Pipe Taper (RC Series Pipe Taper) is based on the Whitworth thread form – a symmetrical V-thread with an angle of 55º.
  • BSPT has been widely adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread.
  • The thread diameter increases along the length of the thread allowing the coupled pipes to form a seal when torqued as the flanks of the threads compress against each other.
  • The taper is “1 to 16”, meaning that for each 16 mm increase in the distance from the end, the diameter increases by 1 mm.
  • Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
  • Intermediate Taps have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole.
