Another advantage of air is it's ability to clear chips out of the cut. This helps give you a better finish. I use it on my X2 CNC mill.

For most of my milling cuts, I don't use any coolant. I'm more likely to use cutting oil or Crisco as a lubricant, especially with aluminum.

Thanks Hawkeye. I will start working on setting up some air.
