Thread cutting & drilling lubricant

[Fred Werring]

Almost embarrassed to say the dregs from 5 gallon buckets of motor and hydraulic oil gets put into squeeze bottles to and gets used for a lot of this stuff....but I don't do much of it.

I, for one, am not embarrassed to admit that the same sources are used as chain and bar oil by me. Even clean-ish drained gear reducer oil is fair game for saw chain oil.

Any oil is better than No oil.
I do as Fred W.and watthour say.
I have several pump type oil cans around the shop. I drain the dregs of whatever bottles, jugs or pails I buy into a 2 gal jug and refill them from that. It's a mix of 10W30, , 15W40, ATF, PSF, tractor hyd fluid, Vactra, even bar and chain oil and refill them from that.
I call it Kikapoo Joy Juice.
Anybody else remember that stuff?

I have an old can of Ridgid pipe cutting oil. I’ve been using it on ferrous metal for years. Works great.
