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.
