Well, it seems likely that 1/8 inch generic...
...pop rivets would work well with a 1/8 inch drill bit. But I'm sure you had that figured out before I said it.
Andy points out that the Olympic pop rivets need a #30 drill to work properly, as the #30 is a 3/16 of a milli-scoch larger than 1/8".
Or maybe I didn't understand the question...
