If you operations are external (OD turning, facing, threading, surface milling, etc.) air coolant, or even just an air pipe, will help. Internal ops (like drilling deep holes) are a bear - that's where liquid coolant shines. A machinist who turns Ti posted on the CPF forum, showing how he set up a liquid coolant system for his SB Heavy Ten. Says that drills that used to get so hot that they'd turn blue, now last & last with the liquid cool.
