I will use the rings as a precise depth reference ;-)))
No, seriously, i want to make bit changing easier. it is a pain to adjust
the drill in a pivoting press to just drill through the PCB each time. I
will set the ring so it just sits against the collet and i don't need to
care for anything.
It will also be of help with the CNC drill later i suppose. I only need
like 0.5mm accuracy.
