Depends what rivet nuts you get. They all need different drill sizes unfortunately.
Search for 'insert nut' on http://rswww.com

The best solution is to measure the rivnut diameter with a digital vernier (they're cheap enough, if you haven't got one already).
Once measured, go up to the next highest drill size - but no bigger. For example, if the diameter is 6.03mm then go to 6.1mm.
I bought 3 drills with the ideal diameter for the 3 sizes of rivnut I used in my car. These came from Tracy Tools (easily found on Google) and they
are kept separate from all my other bits so they're always available (and sharp!).

As said by others... the hole size depends on the particular riv-nut so measure the ones you have!
I found the thinner walled rivnuts with ridges down the side were much, much easier to set.
Cheers,
James

Whatever happened to experimentation ? 
My CBS Rivnut tool says :
Steel: M8 - 11mm, M6 - 9mm, M5 - 7mm, M4 - 6mm, M3 - 4.6mm.
Aluminium: M6 - 9mm, M5 - 7 mm, M4 - 6mm, M3 - 5mm.
And adds check if buying from different manufacturer cos size may vary slightly.

A word of warning try and avoid alloy rivnuts, if at all posible ; the threads are as weak as chinese tea.
and as someone has already sugested get the surrated edge ones , you will find they grip a lot better into alloy and you dont wind up with a spinning
rivnut you cant get the bolt out of.
