End milling involves using a specific cutting tool, an end mill, to make axial cuts into a workpiece. It is an aspect of milling operation used for special applications such as producing die cavities, profiles, slots, contours, shoulders, and other milling parts.Like many cutting tools, end mills have many cutting teeth on the tips but extra cutting teeth on their peripheral sides. Consequently, they are suitable for end-cutting and peripheral cutting. These mill cutters can make exact cuts, making them practical for a wide range of applications, consists of a cylindrical cutter that has multiple cutting edges on both its periphery and its tip, permitting end cutting and peripheral cutting. These cutting edges or flutes are usually made helical to reduce the impact that occurs when each flute engages the workpiece
