Gamebryo LightSpeed “Mangled Metal” technical demo (intro)
I want to get a tool and I don’t know what it’s called.?
I want to put 1/2 inch holes in sheet metal. A paddle drill bit or keyhole saw will leave a mangled edge and mangled bit. The tool I am looking for works like this. You drill a small, perhaps 3/16″ hole and put this device through it. It is a bolt with a hardened steel arbor on it that has a curved cutting edge. on the other side you slip on a nut with an arbor that has an opposing curved cutting edge and as you tighten them together they shear the sheet metal. My local hardware is familiar with what I’m talking about, but doesn’t know the name either. I’m sure it is obtainable on the net but I need help in knowing what it is to do a search. Please help!
Thanks in advance,
Fasahd
I have a better tool suggestion for you. The other previous answers are right: you are talking about a Greenlee brand knockout punch. You buy them in sets with a ratcheting handle and different attachments for the knockout size. However, they are usually used for larger holes than 1/2″. If you are only making a few holes, the best way to quickly get a clean cut for the cheapest price is to buy a Klein Unibit — it will be around $30 but that’s less than a knockout set. This is a tapered steel auger bit with stepped cuts for a range of hole sizes that will fit it a standard drill chuck. This site illustrates them (you need the #59003):

Your best bet would be to go to a local contractor tool and supply store (most places like Home Depot don’t stock these.)
A Unibit will cut heavy gauge steel like butter and you don’t need to drill a pilot hole (it does help to use a hand punch to nick a small dent to center the Unibit on) — be sure to wear eye protection and long sleeves because it will cut so fast that the steel shavings are red hot. I have even drilled clean-edged holes in stainless steel switch plates with a Unibit.
I was an industrial construction electrician for years and cut thousands of holes in sheet metal enclosures using both Greenlee knockout sets and Unibits.
