Mama is going to knock you out..😬
Quick and durable at a fraction of the cost of the brand names..I would strongly suggest in getting these if you’re looking for knockouts in the electrical field

Cuts good
Bought these for doing stand by generator installs. They cut very good. The only issue I have had is that the 1/2 inch KO cutter is a little big. All of the other sizes are good. These cut as well as another well known name brand for much less money.

Cost effective way to make a few knockouts
I used this to make a bunch of 3/4" and 2" holes in wire tray for a solar installation. It went pretty well but I wished that I had either a stubby electric impact wrench or the hydraulic version. If I were a professional I'd buy the hydraulic. The time and effort it takes to turn a wrench on this tool is significant. It works well and if you have time to spare you'll save a ton of money over hydraulic. I put a conduit bender on the end of my ratchet about half way through as a cheater bar. You need quite a bit of force to finish it off. I used it for about 12 2" holes 2 1.5" holes, and 2 3/4" holes. The 3/4" were really easy, the 1.5 I did with a ratchet alone, but 2" is right at the limit of what you can realistically do by hand I think. And that's only if you have room for a cheater bar. For infrequent use, this is the tool to get, especially if you can use an impact wrench. For regular use though, step up to hydraulic.

Nominal sizing
Be aware that the sizes on the punches are NOMINAL for electrical fittings. Not the actual hole diameter.

Worked Great
We use a Knockout Kit at work that was 10 times more expensive than this set. This set worked great for home use, the price it was well worth it.

Works like the expensive ones .
This is just as good as my Gardner bender and it bust the slug . Only thing it didn’t like is I wish they used the same size bolt head on the draw stud so I could use my standard knockout wrench. I think the one it comes with is a 19mm .

Nice set, missing part, TEMCo sent new one
The large bolt is missing. I’ve used other TEMCo products & they were great. I ordered this set because delivery was fast. It arrived on time , but the large bolt is missing. TEMCO has not answered calls or emails yesterday& today. I’m the future , it s easier just to re order & send back to Amazon. It took a few days. but TEMCO replace the missing bolt. So far , these cut well.

The product fulfills its function
It met expectations, good price compared to other brands, it does its job.
