You got me achhhhh....
Back to square holes: That $400 broach is cheap compared to the machine time to make a perfectly square hole, or corner pick down to a very, very fine radius. They would be my first choice for that job. You may be able to call around and borrow/ rent one for a small donation of some sort.(perhaps liquid) That depends on your persuasive abilities. To mill that down to a small corner radius where the corners are not significant I would use the mouse ear method. It will prevent the small end mill from pulling against the two adjacent walls and overloading the flutes. The extra clearance in the corner can be almost imperceptible and you won't get a digger on the wall from the cutter sucking in.
