How you could actually drill a square or hexagonal hole in something, using a circular drill? Well wonder no more!

Seems long winded and very restrictive on what sizes you can do.
Much better off not spending £500 plus quid on a drill press and buy a second had milling machine for a bit more.

Surely a mill would need the same type of oscillating cutter in order to do square corners?

Well yes but i bet you would get a better more accurate job at the end. As that looked as rough as a badgers back side to me.
5mm cutter 2.5 mm radius in the corner and 1 minute with a file it would have a square corner.
Plus what would you do if you wanted the cut out .5mm bigger or slightly bigger on 1 or more sides. You would have to make a new guide.
Its handy and a good idea but in the real world not actually that useful.

Actually it's very useful in the real world of mass production! Like most production processes for repeated production of the same part or feature, fixed sized tooling/cutters are used so rotary broaching is not unique. Even in low volume manufacture, we used it at my last company it for creating internal hex profiles in components and assembly tooling for racing car gearboxes. Our customers wouldn't be too impressed with hand filed corners, and with a hex in particular you want an accurate shape in the corners as that's where the drive takes up.

I used to love that sort of stuff before I got into computers. Still have my old city & guilds in fitting and turning somewhere. If you have ever fitted a door at home, then you probably used a router to cut the grooves for the hinges. Exactly the same simple principal, but on wood.
