Air cooling/SWARF removal

Off-topic, but where can I buy a coolant nozzle? The snake looking type for flood milling.

The cooling due to the air flow from sucking up the swarf will be negligible. I've found the compressed air method to be effective at clearing the swarf when milling Nylon (which is not the plastic you're cutting if I recall correctly), but didn't actually notice any change in the finish since with a single flute tool there's plenty of room for the swarf anyway.

Bear in mind the duty cycle rating on the air compressor you get as you will want to run it continuously, otherwise you will overheat and ultimately break it. Expect to buy a compressor rated for a much higher power / capacity to compensate for having to run it continuously.
