End mill

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, a milling bit can generally cut in all directions, though some cannot cut axially.

Key Factors in Successful Hard Milling : MoldMaking Technology

 · Programming a straight high-speed, high-feed tool path generally is routine, but in milling complex shapes, the load on the tool changes and the machine may not be able to maintain the desired chip load. For example, when a cutter arrives at a degree corner, the tool’s engagement angle doubles and cutting forces increase.
