And punch/punch press, laser, waterjet, plasma cutter, mill, projectile and, of course, shaped charge.

  Plus one for the shaped charge! Waterjets are pretty cool so...

    Applied Science made an experimental (dangerous) waterjet abrasive cutter from a modified pressure washer, https://www.youtube.com/watch?v=Lg__B6Ca3jc https://www.youtube.com/watch?v=Lg__B6Ca3jc

  This being HN, I really expected more how to by Randall Munroe sorts of answers. (BTW, you forgot the railgun, nano-sized black hole, antimatter beam, and trained termite "drill squad".)

    beavers, rats, etc.

    Training termites seems difficult, but I wonder if you could coat the area to be drilled with something particularly attractive to termites or some other insect. Or coat the remaining area with something particularly repulsive to them.

  Electrical discharge milling is so cool, but expensive (tens of thousands of dollars for a machine). It's got to be the most overkill and surgical way to drill out stripped screws though.

    Oops. I forgot about EDM. Should have remembered as I have had EDM stuff done, although a long time ago.
