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.

If neatness really counts, you might want to just drill four corner holes
and use a coping or jig saw to cut from hole to hole. A bit of filing at
the corners and where the saw strayed from the line should produce precision
results.

The Adel Nibbler is good, but I find it hard to nibble to a line, and it
requires a minimum 29/64" hole to start. It is also limited in the thickness
of material it will work with.
