If I had to do hundreds and hundreds, I'd invest in a square hole punch and die for a Whitney hand punch. In between? .. GWE A Whitney hand punch for 10 gauge!?!?! |

And keeping a square punch and die aligned? I've only seen round punches for the Whitney. (Though I would be glad to learn of the ability to do square and other shapes.) In the meanwhile -- what *I* would use would be a 1/4" square broach -- which I already have. However, note that the pilot hole is a little over 1/4" for that, so the sides of the hole will have a slight scallop on each side. I would use an arbor press to drive the broach, and would use a drill press to make the pilot holes, unless the location was quite critical.

A Roper Whitney No.8 will do it.

The No.8 needs 2 hands or a bench mounting device or something similar to use 1 hand.
