Ikea's 35mm Qmax-type punch
It's intended to punch a 35mm hole in their stainless steel sink-drainer (so the sink-drainer isn't "handed") ready to receive a mixer tap. Seems to do that job admirably and would probably make light work of aluminium sheet too.
I don't know what components might need a hole that big (maybe electrolytics?) but £11 to make a neat hole quickly doesn't seem too bad. And there's a pipe-cutter thrown in as well.
Called Fixa, part number 285.121.00 and viewable on their website.
Hope this is of interest.
