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.
