Also known as ballnose end mills, they are rotated against a workpiece to make roundbottomed slots and pockets or mill complex shapes without sharp corners. Each end mill has flutes on its cutting head that carry chips away from the workpiece to prevent damage to the end mill or workpiece. End mills are used on CNC or manual milling machines.

The Azzaroni equation indicates that the correct ball size for the m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the crosssection of the balls charged to the mill.
