Abstract
A milling cutter includes a shank and a cutting head attached to the shank. The cutting head has a plurality of helical teeth, each tooth including a cutting tip, a leading face and a rear face. A flute is defined between the leading face of a trailing tooth, and a rear face of an immediately preceding tooth. A gully of the flute is generally W-shaped in cross section to provide effective chip evacuation. A method for manufacturing the milling cutter with the W-shaped gully of the flute using a split path grinding process is also disclosed.
