5/32 , .156, is the size nose grommet's most use. M&D's and NJ carry that size. I use 5/32 for the thru hole. For the belly grommet holes I use a Letter I drill which is .272. Makes nice tight hole to put grommet in, no adhesive needed. Sometimes you have to take an exacto knife to run around the hole to get the paint out of the edge but I don't find it a problem.
