How to use punch holes in a metal cp
horseboy:
Looks nice. Excellent work. :applaud:
Paladin:
Thanks for the pics, I was wondering how those things work!
Those starter holes look huge, do they make a punch that allows a smaller diameter starter hole? I don't need to make any extra holes right now, but when I do I didn't realize I would have to buy a new drill bit as well as a punch.

Yes, the pilot hole for the 1-1/8" (a.k.a. 3/4" Conduit) hole punch requires a 3/4" hole.
I have TWO Greenlee punches for doing the control panel holes: a punch that punches the 3/4" pilot hole (which in itself requires a 3/8" hole and I already have a 3/8" drill bit) and the 1-1/8" punch.

the greenlee radio chassis punches i have require only a 3/8" pilot hole for the punches around the 1 1/8" range. Just depends on the model of punch I suppose.
