Yep, stinky, thick, high sulfur thread cutting oil commonly used as a
cutting lube by HSMs. It's definitely effective, but also messy.

None-the-less, the ProTool Lube cleanly rinses away with water.

Yeah, proprietary and biodegradable, but that's not my reason for liking
it's usefulness.. and I probably wouldn't have bought the stuff if I'd
looked at the label and spotted the biodegradable claim (incorrectly
assuming that would likely mean non-effective).

I do that too. I look for the skull and crossbones. d8-)

The friend that gave me my first bottle didn't know if it was a decent
product (couldn't even remember where he'd gotten it), but I liked the stuff
from the first few times I used it.
Fastenal used to carry it, but they've stopped (even though they carry
numerous Lenox cutting lubes).. I found more PTL recently on eBag.

Lenox p/n 68040 6 fl oz bottle (also available in gal/128 oz and pails).

Lenox makes good products. I wouldn't hesitate to try the stuff. Maybe
I will after my current can of Buttercut runs out -- or goes rancid
first.

Synthetics are highly regarded in production machining. But there
appear to be a wide variety of chemical compounds that are called
"synthetics." Not knowing chemistry, I don't know the implications of
"amine complex," which is what Lenox PTL is.
