Do you need a rectangular punch like for an old work box? Is this stainless steel?

Better yet, I found a box just for the counter, prepunched.

We cut them in with a sazall, but you have to be very careful as the bezel does not cover much.
However if you have a lot of them to do, Greenlee makes square punches.

For future reference, these sort of controls are _usually_ 'DIN' sized, often '1/8 DIN', '1/16 DIN', etc.
A search the 'xx DIN punch' will get you what you are looking for.
For example:

The price for these punches can be shocking.
Apparently a DIN 192x192 mm size panel cutout became popular in the US, and then fractions of this cutout became prevalent... but Europe doesn't use the fractional sizes. I think I'm going to try to popularize the use of the dodecimeter (1/12 meter) in the US, just to annoy _everybody_.

For example:
Rectangle 92mm x 46mm 1/8 DIN Panel Meter Punch Dies 3.622 inch x 1.811 inch
This punch set is designed for punching holes in panels for common fractional DIN sized meters, gauges and process controllers. The unique design uses an indexed mandrell for male-to-female die rotational alignment ensuring high quality punching repeatability. Fits TEMCo Industrial, Greenlee...

If you have weird sizes/shapes that need to be cut out, find a shop with a CNC waterjet. I use our waterjet to cut enclosure doors all the time. We also built a jig so we can cut into the sides/top/bottom of electrical enclosures on the jet. Very handy for mounting all manner of connector through NEMA-style enclosures.
