Harbro Freight is your answer. This set is $6 and fits any standard electric drill. Much neater than doing it by hand, which I suffered with for years.

Oops, the price is up to $10 but that is still a good deal. I often say that I would hate like the dickens to be a fly shop operator with all the "alternative" materials out there. Thanks for putting this up; my old punches are getting worn.
