Vegetable oil as a cutting oil for machining?

[fandres]

I use chainsaw bar oil most of the time and it works well and is a lot cheaper than cutting oil $10 for a litre of bar oil compare to $50 for 500ml cutting oil.

Where did you find that price $50, I bought 20Lt for that.?
I agree chain saw bar oil is good for a lot of operations though I am sure some will disagree.
