That's right...forgot about PCB bits. They would be perfect for this
application. Though do be careful to avoid placing any side-load
forces on these bits, IIRC they are tungsten carbide & rather brittle.

Do we have a PCB drill press (small, high-speed)? Or PCB drill bits?
Not sure if I'm confusing what NB has with another time & place, but
I seem to recall seeing such things at the space (in the electronics
area, not in the shop).
