| Interesting! A Google search led me to some examples of vix bits. I

They're readily available from many sources as "self-centering" bits.
I got a set from Lee Valley, who offer sizes down to 5/64".

Drilling depth is limited with these bits; but once the holes have
been "spotted" they should be easy to re-drill (use the depth stop on
your drill press) to the depth you want.

If you make a lot of boards, it might be worthwhile to make your
template from something more durable - like 1/8" aluminum, which
should last a lifetime.

An afterthought:

I'm not a cribbage player and haven't seen a board for a long time. If
the holes are too closely spaced for sufficiently deep countersinking
in the template, it might be necessary to make two templates (each
with half the holes) - in which case you'd want to provide some
reliable way to register both templates to a pair of reference edges
on the workpieces.
