I had one a couple years ago but don't know where it went. its got a center drill bit 3/8" with 2 adjustable cutters on each side, you measure and set it to your set size. if you google you'll find some pics.

when your cutting it by hand i beg to differ. for welding/ fuel cutting/ plasma it might be paper thin but try making a hole and cutting a tight radius in it with a pair of snips. anyway, i think that was taking out of context, that tool he showed i meant to say im not sure how it would do on something as thin as even 20 ga.
