All great ideas but I have to be quite accurate with the holes, after marking them out then drilling chances are they won’t be that accurate. The PCB has about 5 mounted parts that need to go through the holes on different sides and there’s no play. Plus they have to be neat. So that’s why Im thinking of making a template I can slip over the edge of the tin box, sort of an inverted U shape and then using a hardened bolt that’s been cut down with a cutting edge done on a lathe that then screws through the die and punches out the holes.

But I don't think they are made down to 5mm. ...Clive

Easy enough to make your own punches and dies using something like EN8. Heat to cherry red and quench in oil to harden. It's about time you built a CNC punching machine.
