Wet chips are not likely to catch fire. Keeping the chips cool is a GOOD
policy for combustible metals like Ti. Compared to everything else,
especially Ti alloys, commercial coolant is cheap. I'd avoid antifreeze,
as it is poisonous. The better coolants have exotic stuff in them to
reduce tool wear. I'm convinced it works, too!
