    The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip the diameter on the ball gets smaller and smaller finally going to zero. As a result the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
