About this item:
- 1/8" x 28 BSPT Taper HSS Tap - Goliath
- HSS Bright Finish BSPT Hand and Machine Taper 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.
- British Standard Pipe Taper (RC Series Pipe Taper) is based on the Whitworth thread form - a symmetrical V-thread with an angle of 55°.
- 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.
- Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
