You use a Die to cut the threads. A Die is like a nut for a bolt. It is designed to screw onto the end of the pipe and cut the threads. Clamp the pipe so that it cannot turn, start the die on the pipe while putting oil on the pipe. There is special thread cutting oil but any motor oil will work. This make the cutting easier. Cut about 1 inch of threads on the pipe. Make a couple of turn and back the die up a half of a turn. Do this until you have an inch of thread. Backing the die up gets the shavings out of the cutting grooves. The new threads will be very sharp and will cut if you wipe the oil off with your hand, use a rag. The dies are sized for the size of pipe, 1/2, 3/4 and 1 inch are the most common.

What is the best to use plastic pipe male thread in iron female thread pipe or male iron thread pipe in plastic female thread pipe?
well 1st of all U need to determine the second pc. as a FITTING, and, after that if the two materials r 2 b used together it doesn't really matter. The best way is to stay with the original materials thru out the pipe system, BUT, if need be to make an easier repair then Plastic(PVC schedule 40) is recommended on any type of pressure not to exceed 80 to 125 psi...2 b safe that is. A higher schedule is recommended above 125psi. PS: normal house( water ) pressure is from about 15 to 50 psi...30 psi is normal
