Have you actually seen a good air mist in operation? A friend of mine
runs a Bijur on his CNC mill. If you hold your finger in front of the
mist stream it takes a couple seconds before a whole DROP of liquid
forms. I agree that squirting a fog of mist around the shop would be a
bad idea, but, in fact, a good mist system puts a LOT less coolant in
the shop and the air than a flood system, with the tool acting like a
paddle wheel to spread the stuff around.

While the Bijur is running the tool barely gets wet. I think most of the
cooling comes from the air blast, with the coolant making just a drop of
lubrication.

I bought a cheap Wico spray system, and it does make a lot more mess
than the Bijur, but still a lot less than flood.
