AMZCNC Manual Knockout Hole Punch Driver Kit 1/2 to 2 inch Electrical Conduit Hole Cutter Set KO Tool Kit ((Conduit Hole Size) 1/2"~2" Knockout Punch kit)

Works faster and cleaner than other hole punches I have used and it was a lot less expensive. Seems to be very well made.

Works great. Just as good as the name brands. Klein

I use these with my 1/2 cordless driver and it's like butter - saved like $1k not getting the complete cordless setup. Seems quality is very good. Should have bought it many jobs ago!

This worked great. It comes with the wrench and case, so that makes this a convenient kit to keep in your tool bag. The holes are nice and smooth without sharp edges. Good quality for the price.

Great product, worth the money works really well have used it for different times no disappointments in this product whatsoever

Worked as advertised, I used it in a solar project to cut holes in a wireway and two conduit boxes. On some of the holes I did have to remove some of the steel pieces with plyers/v grip. One take away, if you use an impact wrench to drive it, it will cut right through in most instances.

Simple, reliable tool. Tough, does the job right every time. Using it to punch all different size holes in wire trough for solar install and boy am I glad I did. Good stuff. I've also used it on plastic boxes (just because I could) and did the job well.

Worked fine on the first two holes in aluminum. The third hole was in mild steel. The draw stud was mangled and the die was completely stripped. As others have said, they need to use better steel!
