TEMCo THA003 2-1/2" Conduit Punch and Die For Hydraulic Knock Out Driver 3/4"-16 Thread

Works amazing and very affordable.

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.

These are very well-made and essential for electrical work.

Using this product to punch conduit entry holes in electrical panel boards.

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

Good solid built products from Temco never let me down. Quality and affordability!

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.
