I don't believe in "lube" for machining, I'll use cutting fluid, mist, compressed air.
I just figure trying to "lubricate" the cutting action is contrary to the goal sought.
Maybe I'm too capricious or punctilious

I thought I would have a practice bashing 8mm dia rivets, cold forming.
The only way is to get them red hot .............. then I might stand a chance. As it stands cold forming them is just out of the question.
Looking back I should have tried cold forming 8mm dia stainless steel first, I would have quickly realized it wasn't going to happen.
So what next .................
see what I can dream up

Semi-synthetic, full synthetic and soluble oil coolants (a.k.a. cutting fluids), plus tapping compounds all have EP (extreme pressure) additives for lubricity. Those EP additives do aid the cutting process, otherwise why would we use cutting oil on HSS drills in metalworking? Or is it just used to have the tool heat up and smell the sulfur laden smoke?
