but with pyramid (3 flute) or profile tools you can get compaction in narrow spaces and this si very much dependant on feed/spindle speed, too slow it compacts, too fast it melts back to the surface,
Hum - sounds a bit like dentistry (I think). Light cuts with fast traverse?
Does an air blast help?
in either case you need a reverse vacuum watergun to clean it up.
Is that also like what a dentist uses?
I am being educated. Thank you.
