This may be a keeper, and it cost far less than the fancy mist coolant

Did you try comparing your cutting performance (such as resulting
finish, tool wear etc) with and without coolant?

Try comparing the finish, you may learn something interesting.

I never ran dry, except as a test. Wet is much better, in every
respect, except for a few materials, such as brass and cast iron.

What I'm seeing with the dribble coolant is that with the mister it
appears that I was not getting quite enough coolant on target.

As always, the interesting part is to do some hands on
comparisons. Whatever I tried, convinced me that flood coolant is
superior in every respect. I did have to add various shields to my
lathe to avoid making a big mess, though.
