Ball or bull nose?

5-4-2008You'd still have basically zero SFM at the center of the ball end mill and a much less stiff cutter. I don't have much experience with this but it seems like if you have the room to run it a bull nose EM has got to be a better way to go for stiffness, lower spindle RPM for a given SFM, etc than a ball nose EM with the same radius. Seems like.
