- 1/8″ x 27 NPT Bottoming HSS Tap – Goliath
- 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.
- 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
- Recommended tapping drill: 21/64″
