Don't get too excited by numbers. You could add a micro-stepping driver and
increase the resolution 10 fold...
Rigidity is about the only thing that matters - everything bends. The less
it bends, the more accurate everything winds up being. The drawer slides
that uses and the dremel-type tool aren't exactly high-precision items
either, so that doesn't help.
I've always thought PCB milling was a bit pointless on a hobbyist level, you
need too much expensive gear (as opposed to other methods) to make boards,
plus it's noisy and a bit slow. Having it drill the holes might make up for
it. Each to their own, of course.
