Goliath 1 1/2" x 11 BSPT 3" HSS Button Die - Goliath F89XHG

1 1/2" x 11 BSPT 3" HSS Button Die - Goliath
HSS CIRCULAR SOLID BUTTON DIE
HSS Button Dies (also known as Adjustable Dies) are designed for cutting external threads.
They are used for threading rods, bolts, and studs, either by hand using a die stock, or by machine using a floating die holder.
They also can be used to cut smaller or larger, than factory setting, by utilising the adjusting screws in the die holder.
Dies are manufactured with a thread chamfer to aid starting.
M2-HSS material provides increased wear resistance and superior thread accuracy.
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.
