I had wondered about that too. I had always related PCB stuff as
similar to metals, where you wanted more cutting and waste removal and
less heat/friction.
I may look into a Dremel press. My Delta is supposed to serve
woodworking duties and it's never around for that lately.
The runout and precision could be an issue too, but I've been lucky to
usually have a clean etched pad/hole to keep the bit centered. That
was one of the things that scared me away from a Dremel-press rig. I
had always assumed that the parts would have even more play in them.
