Stanley Tool on eBay:
Question by : Cutting a circle into a tin can?
I want to cut a 4 inch diameter hole into a tin can (not a soda can by the way, a sturdy food can), but I can’t fingure out how to do it.
The can has a 7 inch diameter and again I want the hole to be 5 inches.
I have tried knocking smaller holes with a hammer and nail in a circle, then cutting between them, but this is messy, awkward, and dangerous as it’s so sharp. I even tried a stanley knife, but the metal was way too tough to slice.
I thought maybe some kind of metalworking drill bit would be the answer, but I can’t seem to find anything that looks like it would work
Anyone have any ideas on how to do it?
Answer by Joe
A tool called a “nibbler” would work. Google “nibbler tool” for pictures and sources.
A nibbler can cut irregular openings in metal, and will work on a curved surface. For your task, I think I’d cut a paper circle, and glue it to the can as a guide. Then, drill a starter hole, and work your way around with the nibbler.
It’s slow, but won’t distort the metal. Work carefully and you won’t have to do much to remove any remaining burrs.
