I need to cut a 30 mm hole in some 0.8 mm aluminium.

I have various hole cutting devices such as Forstner bits but they are for

A bimetal hole saw is the obvious answer, but many wood cutting tools
will also work on ali for one off jobs.

Is there anything clever for cutting holes in metal sheets?

Loads of things... depends on the size of the hole and how many of em
