Specialized plunge milling knives are mainly used for roughing or semi-finishing. They can be cut into the workpiece recess or cut along the edge of the workpiece, or milled complex geometries, including root boring. To ensure a constant cutting temperature, all plunge milling knives with internal shank are internally cooled. The plunge milling cutter’s body and inserts are designed to cut into the workpiece at an optimum angle. Typically, the plunge milling cutter has a cutting edge angle of 87\u00b0 or 90\u00b0 and a feed rate range of 0.08 to 0.25 mm\/tooth. The number of inserts on each plunge milling knife depends on the diameter of the milling cutter<\/p>
