Hi Georg,
Our PCB manufacturers insist on having the drill
drawing.
The drill file helps them to drill the PCB.
The drill drawing shows the positions of the holes
(different symbols for different holes) and their
count. Some useful information about plated and
non-plated holes could be placed there.
Normally we give the size of the finished hole.
They calculate the back-off and the plating
accordingly.
The information of how to drill/mill the slots could
be given in as a separate drawing.

Regards,
Mira
