Brad tip aka brad point bits work pretty good for a clean edge,, Balsa is so soft it will probably rip the first piece a little so use a sacrificial piece on top and keep your stack tight,,, have something to back the last piece to to prevent blow out..

I use 5mm brad tips all the time in my cabinets I build

good luck

example with a pretty well used bit,, still getting some shredding,, but at least the holes are round and straight
