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?

A stepped drill will do if you cannot get a punch. This one has steps
at 3mm so third from the end should be 30mm

0.8mm is quite thin though so important to have it on top of a
sacrificial piece of plywood or similar. Use a pillar drill if you have
one.
Used a scrap piece of decking clamped to workmate.
Cut slowly using Makita battery drill.
All worked remarkably well, considering.
In time to cancel my backup order from Amazon with a range of cutter sizes.
