You can export precise drill locattion by sending out the cnc drill file while generating gerber.
The CNC machine reads this drill file & drills precisely.
Depending what software your using and depending if you want this for singl home prototypes or big batch manufactured boards.
If they are big batch by a manufacturer then you do not need to have the holes, a drill drawing and NC drill file is all that is needed.
For home use I usually stick the drill drawing on the board (through a light box to see) then drill it, then remove & clean off.
However, if your insisting on having the pads look like donoughts then change them to ba an "annulus" and define the inner hole size the same as your drill (or maybe a bit smaller).
