That was one of the main reasons for me converting an X1 micro mill to
CNC.

I have a proxxon clamped to the head so I can drill the boards and
then cut the outside shape without any intervention.

Before the CNC Mill, and depending on size.. I either used hole-saws
mounted in a pillar drill, cut them by hand on a hegner saw then disc
sanded them, or clamped them between an MDF faceplate and a rubber
block on the lathe and turned them.

Trust me.. if you do more than a few, CNC is the way to go.. and you
can cut any shape you like !
