Square hole

[icecycle66]

Is there a trick to cutting square holes?

Like, is there  square cutting tool out there that I'd be willing to pay hudreds of dollars for. Or is it just practice?

You can get drills that drill square holes I think unless I made that up...

I've used a dremel cutting wheel before with a file with acceptable but not great results... I think alot of people just drills the holes and file them to size and shape.

Yeah they make something called a mortising bit. I've used them on wood but never aluminum. You could find a place with a punch or buy a punch and an arbor press.

How heavy a metal can you use your nibbler on? I've got one, and I strongly doubt it could make square holes in, say, a standard 1590b...
