Is there a Greenlee Chassis Punch that punches "keyhole" shapes?
To make things that can be hung on a wall? ...Jim Thompson

| 1962 | I love to cook with wine. Sometimes I even put it in the food.
Greenlee non-circle shape punches start around $200 and run up to $1000 depending on size.
If you are not making electrical chassis... or even if you are making electrical chassis... the tool you want for making small quantities of odd-shaped holes is called a "Hand Nibbler". Radio Shack sells one, as does Mouser, as does McMaster-Carr, etc. Cost is under $10 (Radio Shack type) to $20 (Adel type).
If you already have a circle greenlee chassis punch, use that to make the circle part of the keyhole and then go back in with the nibbler to do the straight parts. Easy.
And if you think that chassis punches are the only way to make round holes... may I introduce you to the Roper Whitney Hand Punch. Far more convenient when they do the job.
Thanks Martin. I squirreled away that URL. Never know when you might need something weird like that. The vendor seems to carry a lot of odd-ball punches and other metal working doo-dads.
Thanks, Glenn! I had forgotten that fitting type. ...Jim Thompson

Yep. After I posted, I realized I already have the tools to do that. I have several small Greenlee's, a nibbler, AND a hand punch ;-) ...Jim Thompson

I know they exist because I once worked at a place that had one... but unfortunately I don't know where it came from.
(And it might have been really old -- that place had been around for many decades, and some of the tools were of World War II vintage, including a Rockwell drill press that still worked quite nicely!)
I think the power cord cut-out is called a "D"-punch. ...Jim Thompson

Often, it's easier to send the panels out for CNC punching, and cheaper to have the supplier make the entire panel in the first place (sometimes almost cheaper than buying a blank panel through distribution) and you can get the color or material (eg. stainless steel) that you want.
I read your post too fast. I was thinking of those snap-in strain relief's which require a D-shaped hole. ...Jim Thompson
