Any thing is better than nothing. Your hydraulic oil is not going to be the best possible, but will probably be about 90 % of the best possible oil/coolant.

Actually Dan, hydraulic oil makes lousy cutting oil, not even close to
being 90% as good as the best possible cutting oils or coolants.

Thanks for the correction. For years I have used what ever is handy including ATF. And believed it was much better than nothing.
Dan
Maybe better than nothing, but certainly not as near as good as
cutting oil. Have you tried bacon fat? Even bacon fat is better than
motor oil. Seriously.

With all of the stearin in it, it won't wick by capillary action. When
you take the stearin out you're left with lard oil -- which has a
decent set of properties (and a very long history) as a cutting oil.
