I've used this method before on other non-FIRST projects that required high precision hex alignment, and it works quite well. The only downside is that you can't go very deep with it on small hex sizes. Typically you don't want to broach very deep anyways, so it's not usually a problem.

That being said, in most cases it's easier to broach. You can hex broach most wheels/hubs for FIRST with just a regular arbor press and some cutting fluid if you're careful, so it tends to require less time than trying to mill it. If you have access to a mill, you most likely have access or room for a press that can broach.
