I use flood coolant, and at my spindle speeds (1200 rpm max) it works very well even on my unguarded mill. No problems with bacteria or smells with modern coolants. It sometimes takes a while for the coolant to turn properly milky again after a few weeks hiatus. I mean, it smells like soluble oil coolant, but that's the smell of a happy childhood "helping" my dad in his workshop. However, I have a job coming up for the high-speed spindle (and I am going to get the guy who wants the parts to be the operator, as he is not paying and wants 180 x 4-operation parts) so I have been setting up some baffles to catch the coolant.
