It is defined as a shank type milling cutter that has a cutting edge on the outer surface and cross-section. An end mill is a tool that rotates and shaves the sides and top surface of a processed item with an outer blade and a bottom blade of a cross-section, respectively. End mills are especially used in precision processing of electrical, electronic and automotive parts and molds.
The performance of an end mill varies depending on the settings such as the number of blades, twist angle, inclination angle, relief angle and coating type, and a suitable shape is required for high-speed cutting operations.
