Cutting a hole isn't an issue for me here, we have a multi-slotted circle that takes a variety of round serrated cutting blades for making holes .. and it fits in all the drills we have. It dates from the 1960s.
However .. if forced to cut a hole away from the chock full of everything tool shed I'd probably scribe a circle, drill a large hole with a drill bit just inside the circle, and put a hacksaw blade through to hand cut it.
Or drill a lot of holes close together just inside the circle, punch out the inner donut and clean up the edges.
Usually there's a plastic insert (in picture of article IIRC) that fits in the hole and has a lip that covers up any ugly rough hole cuts.
DIY is remarkably like programming in the sense of there often being many ways to skin a cat, search for text, or create a hole.
