When I ordered this manual metal punch, I didn't have high expectations. But this thing is SUPER! I was amazed at how easy it was to punch 5/32" diameter holes in CRS 18 ga sheet metal. It will be a lot easier. It just takes a little practice. The built-in depth gauge is very useful. I have about 400 holes to punch and I will have to make them yesterday. So I will practice a lot! For the money he just can't be beat. I'm glad I spent what little money I have on it. It pays for itself the first time you use it.
