Anyone tried these in a VMC?

As someone pointed out, a problem traditionally with rotary
broaches has been the tendency for the generated form to develop
a slight twist. He suggested running the spindle CCW for a while
then CW to keep the twist within limits. Might also improve tool
life.

Opps, sorry. I didn't see this part of your post when I made my
comment: "I'm surprised someone hasn't mentioned "Rotary Broaching",
(sometimes
called "Wobble Broaching"."
