I need to make a 1" x 0.5" square opening in the front panel of an
aluminum enclosure. I can handle round openings, however how do you
make a neat square opening? Thanks in advance.

It is called a nibbling tool. You start with an undersized drilled
hole, and this tool nips away at the edges until you have what you
want. Slow, but versatile. Under $20 for a basic one.

A rotary tool like a Dremel, or one of the larger spiral saws, could
do this as well.

If you need to do many holes of the same size, and need precision,
look into Greenlee punches.

Happy trails,
