Description

1.1/2″ x 11 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 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.
Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
