which side of die to start thread
1 A die head will be attached to cut the thread. 2  Machines now have the ability to thread pipes made of different material, including various types of plastic or resin. 3  A heavy duty pipe threader can also cut your pipe into workable sections.4  The pipe threading machine will be used to thread the end section of your pipe.1. Cease threading when the end of the threading die is flat against the end of the pipe. 1  When the die is even with the pipe, that means the correct threading size has been reached. 2  If you continue pushing after this point, you will damage the thread.
