Knockout punch
Worked perfectly on my AMZCNC hydraulic knockout punch that came with sizes 1/2” to 2” I’ll be buying the larger sizes as needed too.

This with a cordless impact driver makes life beautiful again :-)
Great set for the price. Used up to 2" so far with my Milwaukee impact driver and it's a beautiful thing when compared to a hole saw or paying $1500 for a dedicated cordless tool! Wish I would have bought it a long time ago!

4" = 120mm fan sized
Good punch set. It's going to make you work to get it through sheet steel if you only have a draw stud and a wrench, but it does work. If you're wondering like I did if a 4" size would work for a 120mm fan, I can confirm its nearly perfect sized for that use case. I bought it to punch some holes in my legrand on-q steel cabinet so I could add ventilation fans and it seems to work for that.

Was able to punch through stainless steel.
Worked as advertised. It fit the punch kit I already had and was able to punch through a stainless steel panel. Nice clean hole, no sharp edges.

Works For Me
I needed to punch a 1/2" NPT hole in a plastic vessel, and this worked as it should. I'll update this if there are any issues working with other materials. So far, I would buy again.

Threads gall after just 3 holes punched
After 3 holes punched even using anti-seize in the threads they started to gall. Would not recommend

Does what I need it to.
Works well. Cut through panel and drip hood like butter with my hydraulic punch. I would have paid more in taxes if I bought a Green___ punch and die. I just couldn't justify that extra money.

This die will likely break your ram before making a hole
Junk. I have greenlee dies up to 3" that all punch steel no problem bought this 4" tried to punch 2 holes and it took everything my hydraulic ko had to actually punch hole and I thought it was going to break the hydraulic ram it was struggling so bad. After.2 holes the cutting edge of die looked damaged from punching side on panel. Junk..Junk.. junk
