Hello,

Looking for a chart that shows the correct size drill bit to use before tapping a hole.

Thanks,
Mike

If you have a chance to use an industrial supply house,that caters to machinists and the like,they occassionally will give out drill/tap charts that can be hung on the shop wall.I have one that's several years old that I got that way.It's made of heavy washable plastic and is really handy since I need the info so seldom I don't have it memorized any more.About the only one I remember is that a 1/4 nc tap needs a #7 drill.
