Abstract
A milling cutter having a cutter body rotatable about its central axis with a peripheral wall on the cutter body and insert pockets and clamp recesses located in the peripheral wall. The insert pockets have locating surfaces for positioning an insert when placed in the pocket. There is also a clamp for releasably clamping an insert when the insert is placed in position in the pocket. The clamp freely assumes an orientation identical to that of the insert so that planar contact is made with the insert.
