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 wood.
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
this will do the job
https://www.toolstation.com/adjustab...-cutter/p44999. In thin
aluminium I would use a wooden block to reinforce the pilot hole area to
stop the pilot drill from waggling around
Interesting.
I think it only goes down to 40 mm though.
