Abstract
A milling cutter includes a holder and cutting inserts held in the holder by fasteners. Each cutting insert has an octagonal basic shape and includes eight cutting edges created by the intersection between an upper face and an edge face of the insert. The fasteners bear frictionally against the upper faces of respective inserts. The upper face comprises a number of safety stop projections. In the event that the insert slips relative to the fastener during a milling operation, one of the safety stop projections abuts the fastener to prevent accidental dislodgement of the insert.
