Your cart is empty. Our punch dies are sized to conduit sizes, not actual hole sizes. Electricians use these sizes because conduits are measured by the inner diameter of the tube, not their outer diameter. That means, for example, a 1" punch die will correctly punch for a 1" conduit tube (which has an actual hole size of roughly 1.33"). We've provided you with a handy table below that shows the actual hole size produced by our punch die/conduit sizes in this set.
This set includes a single punch and die set. Punch die sizes are equal to conduit tube sizes. Can be used with TEMCo, Greenlee, or any other knock out punch set.

This TEMCO 3-inch KO punch seems really well made, especially when considering how little it cost. I have a full set of Greenlee KO punches that I use all the time, but needed a fresh 2-1/2" punch and die for a particular job. This TEMCO punch and die performed perfectly for punching several holes in steel pull boxes and a panelboard. It threads right on the standard 3/4 X 16 draw bolt for the Greenlee head. If it only made it through one job it would still be worth what it cost, but it is still going. Of course, I don't know how long it will last, but it worked fine for what I needed it for at the time.

Not high quality but it worked fine with a Harbor Freight 10,000 psi air over hydraulic pump punching 3" holes in a standby generator transfer switch enclosure.

I’m a electrician. I punch lots of holes in switch gear . This works just as good as the expensive ko dies . I’m happy

For the price I’m not sure you will find a better KO in this size. I’ve used it with my Klein KO kit and fit perfectly. After using it to make about 10 KO’s , it’s still performing just as good as the first cut.
