What is a Ball End Mill? - wiseGEEK
2021-2-25 Another benefit of the way the ball end mill is designed is that it can handle very high feed rates, meaning it can mill the material very quickly. This gives it great productivity for use in today’s milling machines. The smooth geometry of the cutting tip also translates into lower cutting forces, giving the cutter added strength under pressure.
