End Mill
While a drill can only cut in the axial direction, an endmill can cut in all directions. Endmills are used in milling applications such as profile milling, tracer milling, face milling, plunging, contouring, slotting, drilling, and reaming.
End milling is the most versatile form of milling that can be used to machine slots, shoulders, die cavities, contours, and profiles. An end milling process consists of a cylindrical cutter that has multiple cutting edges on both its periphery and its tip, permitting end cutting and peripheral cutting.
