Using a die to cut a thread on brass/copper pipe.

Age old "pay for what you get".

In a production environment taps and dies are specified for the material they are cutting.

Personally from past experience I stick to the best I can get for a reasonable price and always in at least a HSS and prefer of they are coated but that adds another dimension to taps and dies.

I will be ordering some HSS taps and dies next time I place an order with Tracy Tools. In the mean time, I am still experimenting with the carbon dies. I have cut another thread on one end of a 25mm piece of pipe. My biggest problem is stopping the pipe from turning so the vice has to be screwed up VERY tightly. The vice I am using has V notches so that does help. But how do I cut a thread on the other end of the pipe as putting the already-cut thread end in the vice will crush that thread ?

Hi Brian make two nuts. Put them on the threaded end and lock them together. You can then hold the job on the nuts.

Yes, that sounds good. Thank you for the idea. I hope the taps cut better than the dies !

AFTERTHOUGHT : the nut will end up so tight that getting it off may be difficult ?

UPDATE : I ordered some HSS dies from Tracy Tools and they arrived yesterday. I have just finished cutting a 3/16-40 thread on some brass pipe : no fuss, no problems, no drama ! The HSS die did the job in minutes.

Forget all about carbon steel dies and always buy HSS.
