Seems to me finishing before drilling would do the trick, helping to
prevent slight tearout. I'm not familiar with kauri, is it a hardwood?
Brad point should work without tearout with the proper feed and speed.
Fast and Fast, I would think.
Literally hundreds of holes? I wouldn't want to drill that many without
a CNC machine! There are jigs you could set up on your drill press, if
one is available. Basically, a fence with a hinged block which holds a
pin that registers to a previous hole, for a line of evenly spaced
holes. I realize the holes are close, so you may have to drill the
first few before you get far enough away to use the jig.

If one were to build a framework to set the cribbage board into, the same
height of the board, wouldn't it be possible to use such a jig for all of
the holes? (securing the four sides of the frame with a band clamp to
prevent shifting while working)

Would tearout be prevented by having a piece of 1/4" or 1/8" hardwood
plywood tightly clamped to the top of the board? With that done, wouldn't
any tearout be confined to the plywood? Also, that board could be the one
marked with the locations, perhaps with an awl as someone suggested.
