ABSTRACT:
The milling cutter of the invention comprises a cutting section having a plurality of blades positioned on the surface and separated one from the other by flutes. At least two blades have one or more smooth segments, exhibiting an even and unbroken land and cutting edge, interspersed with one or more serrated segments containing a row of cutting teeth. The positions of the smooth and serrated segments are staggered from blade to blade so that in the course of one complete revolution of the cutter, each point along a surface being worked by the cutter will be contacted by at least one smooth segment and at least one serrated segment.
