Go back to the template idea...make one from either hardwood or a piece
of angle if you have it (since you said you have a drill press, this
should be easy). Go with a twist or Forstner bit (although if you make
a pilot hole first, a twist drill bit should be ok). To
minimize/eliminate the tearout, clamp a piece of hardwood or flat iron
on each side...

Whether there is a 14 mm router bit I don't know, I've not researched
metric sizes, but if it is actually a 14 mm hole required by the hinge,
there has to be a corresponding tool...

I've used a lot of Soss hinges over the years, but at least when I was
using them they were English measurements...
