I mostly agree but sometimes I've to make a hole with not that tight tolerances, or sometimes you want to tap (not a critical thread) and you don't have that specific 7.3mm drill for this M8 thread, and you just drill it 7.5mm... I do that sometimes, but not very professional I agree

Hello Herbert,
Apparently this patch has not been merged in the master yet.

PathDrilling(77).circularH...

Thank you all for your replies.
I made a little screencast to show you what I'm doing so that you can see if I do something wrong:

You see at the end of the video I get this error message in the terminal (see my first post).
