Wouldn't a square broach work just as well and take less time?

It might if you don’t want a blind hole.

This "drill" appears to be able to cut a blind hole that's square for the entire depth, which would be much more difficult for a broach.

I was about to say that broaching would also require a separate machine, whereas this device can be used as another step in the same machining center. However, I don't know that you can't broach in a machining center. I've never seen it done, but that doesn't mean people aren't doing it.

Not in a blind hole, nor a through hole that prevents the broach from passing all the way through (a hole thru a pipe wall from od to id).
