    Does anyone know of such a tool to punch a hole onto the panel?

    Yes, and they can be quite expensive. How many holes do you need punched? If it is only one or two, then a scribe, drill or scroll saw/coping saw to rough out -- a nibbler also works --, Dremel with carbide burr, and file will work fine.

    Hello,

    I know that Qmax do a tool for the 25 way 'D' connector, as I have one. As for the 9 way, I made a tool that I use on the fly press.

    here you go >> http://www.mcmaster.com/#knockout-punches/=7sfb3o

    but as others had said, a drill motor, drill bit/s, and some jeweler files is all you would need really to make a one time hole....

    as these are the only tools I used to make the holes below on an XBox360 console...

    I guess this is a good example of the laws of supply and demand. If db9 and db25 connectors were used a lot, say, on every one of the millions of personal computers sold in the last 20 years, the punches to make the mounting holes would be cheap, like $5 each. Right?

    Yes, GREENLEE makes them; I have a 9 pin one right in my hand here. Alas, it's not mine, however....as they're quite expensive. If you plan on doing a LOT of this, it might be worth the investment...but otherwise, you''re best off borrowing one.

    Thank you all for your help. I really appreciate it. Esp the pictures. :()

    I think I will have to go with the cheaper option because the circuits I have design are cheaper than the knock out punches. Maybe I will just replace the db9 connectors with something more rectangular and right angled.
