Default I need to cut a large hole in sheet metal.

The hole must be neat and cut in situ.

Is there a gadget constructed like a compass
that when rotated often enough will cut such
a hole?

Rather like the typical rotating glass cutter
used for cutting large holes in plate glass.


Sure. It's a circle cutting attachment for a plasma cutter.
