McMaster-Carr has drill rod down to 0.0135 inch (#80 wire gauge size).

Assuming that you lack access to a lathe to turn down larger stock to make a punch, I guess you'll have to make do with a short length of the correct diameter drill rod. You can try chucking it in a drill press and using the drill press as an arbor press, or else just carefully hold the rod in place with pliers while you tap out the pin.
