Just wanted to add that most cities will have an industrial supply house for machine tooling and such (end mills, taps, files, etc). Just go in there and they can easily give you any tap you wish with the corresponding drill bit. Also the prices and/or quality of the items tend to be much better than bicycle related sources.

I find a 10 mm x 1 mm tap nice to have for the derailleur drop out. For just chasing threads, if you are courageous you can clean up with a 1/8" pipe tap (!) - just remember that it is tapered. If you go in too far, you have just made a unique 11 mm dropout. I haven't found matching derailleur mounting bolts for that size. Fortunately, I haven't needed one.
I also keep a pair of 9/16" pedal taps at home. Sometimes they are used for chasing threads -- just this week, in fact. More often, they are the instruments of blasphemy: I have converted a lot of 14 mm (French) crank arms to 9/16". The change is invisible, and it has been much easier not to worry about separate stocks of pedals for the bikes we ride.
