No, it isn't. A hole punch is a tool consisting of two hardened steeel
circular punches plus a gadget to press them together - you drill a
small hole, put the bolt (with the bottom part on it) though, put on the
top punch and lever, and fasten it until the punches have cut through.
About $60 hereabouts with a set of pro quality punches, and a wise
investion.

Of course it is. They'd have to take out all the boards to do it safely.

You need to drill a hole for the punch as well. The advantage of the
hole punch is that it leaves a clean-cut centered hole with minimal
effort, for which you'd otherwise need a stand, have to build some
contraption to fix the JP-8 to the stand, and spill a generous amount of
drilling lubricant across the case.
