ABSTRACT:
A milling cutter blade with a notched cutting edge capable of being mounted at a desired negative or positive rake in a cutter body, the notches having side walls which, at the side face, diverge away from the cutting edge. The blade edge surfaces adjacent the cutting edges are of concave, generally V-shaped configuration with the junctures of these edge surfaces with the side faces being at an acute angle. A plurality of the blades are mounted in a cutter body to form a milling cutter assembly such that one portion of the configurated concavity V on the blade back edge surface is in reference engagement with a like oriented cutter body reference surface on a convex generally V-shaped back surface of a cutter body blade slot. The V-shaped concavity on the front edge surface of the blade cooperates with the adjacent chip pocket of the cutter body to discharge chips.
