Why don't you just **** on it, Dan, and see how that performs?


ATF is a low viscosity lubricant good for high pressures and has good antirust qualities. _Pretty much the properties needed for a cutting lubricant. And since it is used in millions of automobiles and sold almost everywhere.. So it is inexpensive.

**** on the other hand is cheaper, but is not good as a high pressure lubricant. And it has no antirust properties. As a cutting fluid it would work for removing heat, but water is cheaper and is better as far as rust is concerned.



And why buy ATF for an experiment when I already have real cutting oil that works?

But since you have not used ATF as a cutting libricant, I contend you are not qualified to tell others that that it is not good. So keep using your real cutting oil, but why don't you quit saying it is not good for home shop machining. You admit you do not have any experience with it.
