Various places have resharpened, retired from production use, carbide
bits. One example (among many) at
<http://www.allelectronics.com/make-a-store/item/DRB-9/9-PIECE-ASSORTM...>

Carbide is kind of brittle, though. I usually go with high speed steel,
which are a bit more forgiving of hand-held drilling. (No pun intended
there. Really!). MicroMark is my usual toy store, er ah, go-to place for
things like that. Sets available
<http://www.ares-server.com/Ares/Ares.asp?MerchantID=RET01229&Action=C...>
or individual sizes, down to 0.0135 inch.
