Sheet Metal Tool

Looking for a hand tool that notches sheet metal for 1.5 tubing. Had the web site but I lost it. Any help would be appreciated.

I think you're talking about Knockout Punches. Harbor freight has a kit, but it doesn't go up to 1 1/2". Everywhere else is pretty expensive for just 1 punch.
