Like Goef, I direct coolant lines to hit in key areas on every tool being used. However if the coolant system that your offering is of good quality the uses in High Speed Machining are more valuable than short production runs.
Everything has a place and every tool has a purpose. Remember too that many shops are looking for cold air cooling because of the problems in waste handling, and thermal shock.
