This is the setup I have. Uses air line to pull coolant/lubricant out of a 5 gallon bucket under the table. 
Here is their website. https://cedarberg.com/products/snap-loc/e-z-mist/
My table has built in reservoir with drain plug at the rear where it returns to the bucket. A few of it in use. 
This is the coolant I use in the bucket with water. https://www.tricocorp.com/product-category/metalworking/lubricants/ 
For drilling off the drill press where you can't flood the piece Mystic Metal Mover or Tap Magic is great.
