Yes, that $42 product can do that.

the $42 unit (https://www.vevor.com.au/metal-nibbler-c_11028) will cut that easily, and quite neatly. I have one of those units (same model, just different brand from before vevor existed) and it runs well on a cordless (or corded) drill, and I use it all the time for cutting vents in corrugated (or trimdek profile) roofing materials.

It won't cut it, the hole is too small.
By vevor
Minimum cutting radius is 300mm as shown in specifications

No, it won't cut a 100mm circular hole.
