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

Is there anything clever for cutting holes in metal sheets?

If you haven't got a (Qmax) hole punch or hole saw then something like

stop the pilot drill from waggling around
