Ball end mills are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multidimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. Because of the shapes required in these products it''s common that multi axis machining

In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.

If you are using an 8mm ball mill, then 6mm stepover is still very aggressive and will leave a very irregular surface for the finish pass. The goal is to get as uniform a surface as possible for the finish pass so the cutter bends by a uniform amount. Any change is the amount of force on the cutter will show up on the surface of the finish cut.

Ball hardness is in the 60–67 HRC range. They wear better than 440C stainless steel and throughhardened carbon steel. They are also recommended for appliions where a throughhardened steel ball is needed in larger sizes (½" and larger). They are sometimes packaged with a very light oil finish to reduce rust due to humidity.
