I needed a smooth hole bored into a large metal cabinet to run a power cord, this did the job quickly and efficiently.

I was installing an electrical system for a 3200 sqft mixed-use building. Everything was surface conduit with 4†boxes and pull boxes. Multiple boxes needed a hole or a different size hole and these punches came to save the day. I imagine a hand wrench or socket set could be used, but I used cordless impact wrench and it gave me the hole I needed within 15 seconds. It worked well in a tight space and was way better over a hole saw.I’d punch out the smaller plug and use the hole cutter for the larger needed hole. (1/2 knockout to get 3/4; 3/4 knockout to get a 1â€). I didn’t try it, but I think the 3/4 punch bolt is larger so you can’t use a 1/2†knockout for a 1†hole.

I needed a larger knock out in an electrical box. This kit took care of it quickly and effectively.

Works as good as a Green-Lee set; Now I'll see if it works for 10 years. You can't beat the price.

Makes a neat hole in sheet metal. Requires a 0.525†pilot hole in order to do the job. So you’ll want to buy a 9/16†drill bit to make the pilot hole.

I had to return this because I picked the wrong size, but I was very impressed with the quality of construction and packaging. A similar item of lesser quality was $69 at a hardware store.

The functionality of this is spot on....but someone didn't think to include a storage box for this set.

This manual knockout punch kit did the job in creating a 3/4" hole in two metal electrical outlet boxes to receive 3/4 inch conduit. Works much better (as safer) than a drill bit.

I never did use this tool. Who knows, it might work great! I had purchased it as a backup for the 1/2" K/O cutter in our Greenlee knockout kit. This will not work with the Greenlee ratcheting handle. It is a stand-alone Knockout cutter.
