ABSTRACT:
A milling cutter comprises a cutter body having at least one insert blade station. At least one insert blade is operably connected with the cutter body at the insert blade station. The insert blade has opposite side faces, and a plurality of peripheral edge faces, with at least one cutting edge formed at the intersection of one side face and one edge face. The insert blade is oriented in the cutter body such that the one edge face defines a tooth face against which a workpiece impinges during cutting, and the one side face defines a clearance space between the insert blade and the workpiece. The one side face is convex in shape to reduce the clearance space for improved cutting efficiency and blade longevity, without causing undesirable contact between the other portions of the insert blade and the workpiece.
