Goliath BSPT Taper HSS Bright Pipe Tap

• 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.
