Cutting Oils
The specified thread cutting oil is not readily available.
Is there a suitable replacement that would work well enough in a pinch?
Diesel - probably too thin?
Motor Oil - probably too thick?
Something common that I could pick up at the hardware store? Looks like the main ingredient in the Ridgid brand is mineral oil... so generic mineral oil should work almost as well, right?
Thank-you!
You must be someplace really remote to not have anywhere to get cutting oil on a Saturday.
they also make an aerosol spray can oil.
since your hand threading and not doing fast production work, i believe any decent lubricating oil will do.
in fact i have an oil less threader #1210 1/2''-1'' that uses a cooling fluid at a drip rate. sure the dies are titanium nitrate coated. but the threads come out like a factory nipple.

While not really the right stuff #30 non detergent automotive oil is far better than going dry. If you can hold off until Tuesday try a good plumbing supply house. They should have threading oil.
I'd never attempt to cut dry but I'm hoping to get some mineral oil at the hardware store over the weekend. The Ridgid Nu-clear is 95% mineral oil and 5% sulfur. The Ridgid Dark is 90% mineral oil and 10% sulfur.
Does anyone know what beneficial properties sulfur adds to the oil?
basically the slickness.
the oil is designed to prevent galling to the threads.
So with the sulfur I'm assuming will get a much better final thread.
Do you think I'd notice a difference in ease of cutting? Longer tool life?
This is good education. As far as my project goes, a few cuts with 100% mineral oil shouldn't really be an issue, no?
Thanks! I'll try a couple things I have here and then get some mineral oil if required.
But getting the proper oil is no longer the point. I can get generic cutting oil at Ace Hardware, I can find mineral oil someplace else, and I have plenty of SAE 30 here.
I'm simply asking all these questions in order to educate myself further.
Understood, nothing wrong with wanting to learn more.

Yes I am someplace remote.

My guess, and it's just a guess, is that it all has to do with speed.
Higher speed means the friction creates a lot more heat in a much shorter amount of time. Dissipating heat => coolant.
With slower speed, friction is more difficult to overcome due to less tool momentum; and the heat caused by friction has more time to dissipate. Overcoming friction => oil.
I think machine shops use various mixtures of oil/coolant depending on the operation, machine, and material.

the sulphur adds to the lubricity of the oil.
