In Reply to: I've used a Hole saw on my old metal control panel. Optimum would be to find a punch I called every hardware dealer in my yellow pages with no luck every size but 1-1/8" posted by johnpurs on 8, 2001 at 5:09 PM:
I had the same prob with my silverline cab.
It seems that a bi directional metal bit (what i tried first) starts to over heat the metal and in my case the drill. You could try drilling lots of smaller hols and then punch them out or take your panel to a sheet metal works like i did. They bent the metal and punched new holes for me for 15 pounds.
