|sedanbob||Good to know - I'll file this in my memory. I haven't had to cut many threads in stainless - mostly just thread-chasing, but I will sometime. Thanks for the info.|

and you can bake biscuits on the other side at the same time. sounds like a neat trick in a pinch. worth a try .

This is what we use at work. Awesome stuff! This makes a huge difference in the quality of threads your die will cut.
I believe it's the moly that makes the difference between this and other cutting fluids.

I'm sure for the few you are doing a carbide threading die will work, but it will take it's toll on the die. The thicker your lube is, the easier it will cut. Believe it or not, but the old timers in machine shops used to use Crisco shortening on their material while cutting SS. I watched an old timer cutting this way on a machine many years ago, using a brush applying it as the tool turned.|

Thread cutting oil for stainless steel?
Still working on this project. I have ordered a new rod of 1/2" 303 stainless ans the only American made cutting die I could find (Irwin). Everything I have read says to use a good cutting oil for stainless and many recommend Rigid Extreme Performance-but i can only find that in gallons and I only need to cut two 2" long thread portions.
Any suggestions for a less expensive but successful substitute will be greatly appreciated.
