Since those holes really makes a difference for chip removal...
You might be able to set up internal coolant for one tool if you use some old quick connectors for air, they tend to rotate if there isn't to much pressure if worn. A connection stright up from the turet, a 90 degree connection and some elastic band should be able to keep the supply hose in the desired direction.
If you want high preasure grab an old HP-washer, you'll likely end with a combined lathe shower though :-D
(And I surely doesn't want those fluids when they got bacteria in my eyes.)
