If you ever need imfo on drill and tap size, just shout, metric is easy, just deduct the pitch from the tap size, and that is the drill size, for example, 8mm tap with 1.25 pitch = 6.75 drill, 6.80 will do.

I wasn't sure about Bobs logic re the M8 x 1.25 tapping drill size, but according to all my drill charts 6.80mm is the correct size.
Certainly for metric coarse it seems to work out correct.
