Stefan:

I am curious WHY you want to "adjust" these plastic rings, as they are used
in professional PCB drilling ONLY to support the bit in a magazine for the
automatic bit-insertion step in CNC operations using more than one size bit,
AND, as a place to print the diameter of the bit. That is, the precise
vertical location of the ring is not used as any "depth reference"; nor would that
"stay", anyway!
