End mill - Wikipedia

An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, most milling bits can cut in the radial direction. Not all mills can cut axially; those designed to cut axially are known as end mills. End mills are used in milling applications such as profile milling, tracer milling, face milling, and plunging.

Milling Process, Defects, Equipment

End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.
