Standard square push broaches?

[Munty Scruntfundle]

Hi there.

Does anyone know where I might find a 3mm standard square push broach? I'm struggling to find anything small, 4mm seems possible in a full set costing £800, which I'd sooner avoid!

Or is there anyone out there that could make one? I don't have the ability to cut hss here and I don't really want to tool up just for one broach.

I know this is easily possible with rotaries but I don't have a lather here yet.

All ideas welcome.
Thanks.

thought about a rifler file?

What are you trying to achieve?

ArcEurotrade sells them down to 2mm

Filing would mean buying more hardware, I don't really want to, and bugger doing it by hand, too many holes.
I'm trying to achieve 3mm square holes in brass. I thought a broach would be fastest.
ArcEurotrade, I will have a look now. Many thanks.

could you not make one from o1 and heat treat it?
