I honestly have no idea. I wish I knew, because then I might pursue it further.

We broached some HTD 5mm pulleys that were 1/2" wide, and a few of them came out crooked. This was probably due in part to poor technique (and execution), but I would not trust most of our team members using our current setup for high-speed applications. (where the broached piece is running at high speeds)
