[Shop-talk] Square Hole?

[Ian McFetridge]

If your tolerance are not too tight, you could do it like with wood:  drill
with a slightly smaller bit and then file (maybe dremel) out to square
size. (you knew this, but mentioning it for completeness)    If your
tolerances are tight, I think you may need to enlist the help of a machine
shop with something like a water-jet cutter.   A press and punch will do
smaller gauge material, but I don't think it could do 1/2" brass.
