In metric countries, metric drills are labelled just like in the US - 
check out any industrial supply company catalog such as Grainger. 
Metric drills are labelled by their size, e.g.. 5 mm, 5.5 mm, etc.   
That is what makes the system so easy to use!
Same goes for screws.
Same goes for center pins: 1.30 mm, 1.35 mm etc.
Tuning pins are usually referred to by their size as well: 7.10 mm, 7.25 
mm...

No more charts, tables or books to refer to.  Easy as apple pie.  Oops, 
that's an American standard!
