Drilling holes on cnc

The comment was to somebody who has no experience with it.

I started with no experience, I used HSM Advisor with the good advice to start at 50% of recommended feed and see how it goes, air and lube and I didn't break any bits in Aluminium, it's easy-peasy, try 304 SS, that's more challenging ;-)

That's very good, but I am not that perfect, so yes, it did happen that I broke a bit or two, and in fact, even today it can happen. I don't think there is a shame in that.
