This set consists of 55pc metric drills from 1-13mm in 0.5mm increments.

It also has the tapping sizes included which are 3.3mm, 4.2mm, 6.8mm and 10.2mm.

1.0mm to 4.0mm x 3 of each size

Also a very good feature on these sets is the box itself;

If you are unsure of the size on the drill there are slots in front of each size, so slide it down and where it stops that is the size of your drill.
