Hi All,

For my first aluminum job, I need to mill a series of 6mm wide slots, 10mm deep in aluminum. I have a decent 6mm, 1 flute end mill. Looking at various Utube articles, most people have an air blast system of some kind aimed at the endmill to keep the slot clear. Can anyone recommend such a system I can fit?

If I have an air blast system fitted, do I also need a coolant feed? It would be much cleaner if dry milling was OK.

Can the air blast be replaced by a vacuum device instead?

Cheers

Gary
