Cutting oils - which produce lowest vapours-smoke

[maple syrup]

Hello,
I'm new to the forum.
I have made it a habit over time to try to us products in all sorts of applications that are either environmentally friendly or safe to use. it's always a challenge. yes they don't always have the best performance, but that is the trade-off. I was watching a YouTube video that one of the name brand cutting oils produce terrible vapours when used in the shop.

currently, I would only be using a cutting oil at a drill press And tapping threads and don't ever plan to use it outside of that.

I therefore started looking into a food grade cutting oil From a well-known brand thinking that would be safer ( vapours or smoke). after reading the safety data sheets, it is clear to me that even foodgrade products can be hazardous to the health. but it is unclear to what degree. some vapours (Outside of cutting Oil applications) are not great for you, and some are very harmful.

I have also read that some people use canola oil, but the downside is the viscosity changes pretty quickly and it can go rancid over time. I wouldn't use it outside of a drill press as it would need to be cleaned out after use.But even for a drill press, I would use it if it was good for that

so the question is,
which Cutting oil products produce the least amount of harmful vapours or smoke during use? Which have low VOCs?

Bacon grease?

This is what I use per recommendations from this board:
Anchorlube https://www.mscdirect.com/product/details/00063909
It does a great job for me! I usually thin it with water.

I use Anchorlube. It rarely vaporizes and makes fumes. Tap Magic works great, but it smokes and gives me bad headaches. I only use Tap Magic now for tapping and parting.
I dilute the Anchorlube with 50% water so it is a little soupier. Still sticks on surfaces, which is what you want. I do find it is slightly harder to clean up, but that is the tradeoff for me.

Probably carcinogenic.

I wonder how many machinists have died due to inhalation of cutting oil smoke ? in the history of machining ?

Probably have more deaths due to smoking of pot than of smoking of cutting oil (although different processes are in lay.)

Being around jets for 9 years and a tech at Ford dealers for 18 years, cutting oil smoke is the least of my worries, also a cigarette/cigar smoker........

Probably carcinogenic.

only if you live in California.
