You can drill them with a 1/16 drill bit, and 1/16 collet. Need to experiment with RPM spindles have less power at lower RPMS probably a minimum recommended rpm for your spindle. 1/16 bits are cheap if you burn up a few. If it not to thick I would just drill it in one shot.
That being said, could you jump up to .125? A .125 hole is 4X the area of a 1/16. You have a cnc why not get creative instead of a bunch of holes?
