Se ve que tiene buena calidad el producto Pero no quisiera pensar que es económico por que tiene defecto

Works great, cuts up to 20 gauge easily. 18 it struggles but works

Despite some critical reviews, this knockout punch worked perfectly for my needs. I needed to add an external RV plug in my garage, and it handled standard electrical boxes flawlessly. The punching ability of this tool is excellent—it cuts through the material cleanly and effortlessly every time. The holes were cut precisely, making the job quick and easy. I’m not planning on using it commercially, so for the price, it’s an absolute steal. Considering the limited amount of punching I’ll be doing, this tool will easily last a lifetime. Highly satisfied with its performance!

Great tool for sheet metalwork

These knockout punches were perfect for cutting a hole in my stainless steel kitchen sink for a filtration system faucet! I had to do it in two steps, a smaller die to cut the hole for the bolt for the larger final size die. Everything worked great!
