How Bad is it to Drill on a CNC Router?

I had long heard (and myself repeated) that drilling on a CNC router was less than ideal. But just how bad is it to drill materials at 10k RPM? That’s what I wanted to find out for myself.

I’m using Short/Stub Length drill bits from McMaster (https://www.mcmaster.com/drills) but there’s nothing special about them. Shop around!
