This season, I just got sick and tired of seeing students struggle with our cheap A$$ harbor freight drill bits, that I went ahead and purchased 4 of each of the following from McMaster and we keep them in a separate storage container, labeled and all (including what it is used for)... These are all the clearance and tap sizes for most popular screws from #6 to 1/4" as well as 1/8", 5/32", and 3/16" for rivets.

We still have a full 115 pc harbor freight indexed set, but that's just for special jobs.
