Drill bit size for front sight pin on a 686+

So I'm replacing the front sight on my 686 with a HiViz replacement. The replacement has to be drilled for the pin, but all of my fractional bits seem to be the wrong size. I figure it must be a numbered bit??? Anyone know what size number bit I need to buy? THANKS!
