Depends on what you are maching. I use kerosene on aluminum all the
time all you need is just a little to keep the tool from sticking.
Coolant is nice in enclosed machines but is very messy on open lathes
and knee mills. Spray mist works well for lots of applications and
isn't nearly so messy. I use an acid brush to apply cutting oils on
small parts and it works well.

Thank you Charlie for the kerosene tip with aluminium
For iron spray are very expensive. Is there another way? Like some drops of
oil mixture?
