I bought my drill bits at drillbitcity.com . I manage to break the
smaller ones through my clumsiness before they wear out. They have
some good variety packs that will probably handle most of your
drilling needs.
I did not have much luck with a dremel. Mine had too much runout. I
ended up buying a high precision mini drill press for drilling my
really small holes. For a less expensive option I think some people in
this group have attached a high speed motor to a long cantilever and
used that for the drill press.
Sizes can vary, but one thing I learned is when I create my pads in
Eagle Cad I make the holes undersize so when I drill I get copper
right to the edge.
