I need to have 10 small square holes drilled and rectangular window milled into
0.040" thick aluminum housing. Does a U.S.A company provide this custom service, since I will be needing multiple housings pre-drilled? Thanks in advance. JohnDoes the shape of the housing create a reason why these openings can't be punched?
"Drilling" square holes, while not completely impossible, isn't done very often.

I bet you could easily make a punch and die out of 4140 or even a mild/medium carbon steel to punch those holes, if you only need like 100 holes or something. Normally the component that fits inside the hole covers the edges of the hole anyway, so a great edge wouldn't be really necessary.
Got some files and a drill press?
Regards,
Robin

I need a rectangular hole the size of 1-3/16" by 1/2" wide. Do not prefer to punch and then mill it myself. I do not have the time and experience to make these holes myself. I also need 1/4-inch diameter by 18.5mm extension shaft and 10 BA screw.
Any sheetmetal shop should have the capability to do that stuff. They'll punch or mill it as needed. I've got maybe a dozen or more shops that can do such around my neighborhood.
