摘要：In a milling cutter comprising a cutter body having a plurality of cutting insert-receiving recesses spaced about its periphery and cutting inserts removably secured in said recesses by clamping means, each insert having two opposite, substantially plane, end surfaces with side surfaces between them, the improvement wherein the side edges of each cutting insert are formed with clearance angles beta equal to one-half that clearance angle alpha which is necessary for the functioning of the milling cutter. Each insert is positioned, in its recess, with one side edge resting against a support surface that is planetarily ground in the cutter body substantially parallel to its rotational plane so that the angle which one end surface presents to said planetarily ground support surface is equal to 90 DEG -( alpha /2).
