I need a 3 or 4" long piece of round stock. The dia. can be from 1/2" to 3/4". What I am doing is cutting a test thread with my new Dorian threading insert tool. I tried to cut a 1/2" NPT for a customer on a Monel 400 nipple with HSS and it did not work. The tool dulled to fast and tore the metal out.
I tried to thread like normal and it soon was ripping metal and cross threading because of the load. I have since found out Monel should be machined at slow speeds and fine cuts, or so one site said. I did use 75 rpm but I used to much DOC.
I tried the carbide insert threading tool on some unknownium SS and it did fine. A member of PM has some copper I will purchase monday to cut a test thread on and I need some Monel 400 now.
Does anyone have some I can buy or do you know of a supplier that will sell me the small piece I need? I was greatly surprised at the price of Monel and that is why I am looking for a piece just big enough to do the job.
