Re: gEDA-user: Constraining Drill Tool List?

Not really.  Most fabs limit themselves to at least wire size drills,
but WHICH wire size drills are available is variable.  Some fabs have
the full range, others limit you to a handful before charging you
extra.  Wire size drills would be a reasonable default for PCB, but
this is yet another constraint you must ask your fab about.

Note that drill sizes are before through plating, of course.
