Use a rotary broach. The cutters can be found at reasonable prices. The holders
tend to be stupid expensive. Fortunately there's plenty of DIY info on how to
build your own.

That was my next plan. AvE has a very quick and dirty variant on Youtube too.
But for this project,
I just saw this last week. Hemingway kits has a compact rotary broach
kit. I am not sure if it can handle a 10mm square.

I do EDM on my little HF mill Andy. But I connect the EDN power wires so
Andy -
The guys at the shop where I last worked beside used to slightly grind the
flutes of a standard end mill, leaving (say) 6mm of flute length for
cutting pockets.
That way, the "higher up" flutes did not re-cut swarf, and thus deflect the
tool, and there was no tool rubbing on the higher up

It won't be quite square but how about drilling small (1mm?) holes in the
corners, milling out the centre and cleaning up with a small endmill? It will
be at least as good as a typical 3/8-inch socket.

You could mill a 10mm wide x 5mm deep slot in two rectangular bars, then
silver-braze them together.
Might not be strong enough, depends on if the OD is big enough to leave a
reasonable joint area.
Welding would probably leave a hardened zone and be miserable to machine
afterwards.

It's a blind hole (and needs to be).
I have thought about making a wobble-broach.

I want to make some D1-4 cams for a 4th-axis project.
These need a 10mm square hole (but 3/8 would be fine too).
I don't think I can polygon-bore a square, it needs too much
tool-relief. (I guess I should try, though).
If I could find something like a 3/8" drive socket with no hole in it
