- 3/8" x 19 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.

- 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.
- National Pipe Straight (NPS) - Parallel - made to American Standards).
- Used for free-fitting mechanical joints where thread sealing is not required.
- Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
- Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap.
- Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
- Recommended tapping drill: 14.5mm

- HSS Bright Finish NPT Hand and Machine Bottoming Tap.
- 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.
- National Pipe Tapered (NPT)is a US standard for tapered threads used to join pipes and fittings.
- ANSI/ASME standard B1.20.1 covers threads of 60º form with flat crests and roots.
- The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other.
- However a clearance remains between the crests and roots of the threads, resulting in a leakage around this spiral.
- This means that NPT fittings must be made leak free with the aid of thread seal tape or a thread sealant compound.
- For each 12" increase in distance from the end, the diameter increases by 3/4".
- Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.

- HSS Bright Finish BSB (Brass) Hand and Machine Intermediate Tap.
- These general purpose taps are ideal for creating new threads in a wide variety of materials.
- 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.
- British Standard Brass - brass tubing has a uniform wall thickness, irrespective of the tube diameter, therefore any thread cut on, or in, it needs to have the same depth, so 26 TPI is standard on all BSB diameters.
- BSB is often confused with BS Cycle thread, the difference being that brass thread has an angle of 55º whereas Cycle is 60º.
