Ball end mills have a rounded nose and create a roundbottomed groove in milling tasks. 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 .
