What is a Ball End Mill?

Oct 30, 2020 A ball end mill is a type of end mill that is especially suited to machining three-dimensional contoured shapes, such as those in molds and dies. It has a rounded tip which is designed to give an improved surface finish to the material being cut.

What is a Ball End Mill? - wiseGEEK

Oct 30, 2020 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.
