A cutting insert is made of cemented carbide or ceramics and is intended for putting machining of metallic materials. The cutting insert has a central hole (9) which is threaded. This makes possible larger hole diameters and thereby larger fastening forces than for hitherto known inserts, which have smooth hole surfaces.

Une pièce de coupe rapportée en céramique ou carbure cémenté est destinée à l'usinage de matériaux métalliques. La pièce de coupe rapportée comporte un trou central (9) qui est fileté. On peut en conséquence prévoir des trous de plus grand diamètre afin d'obtenir des forces de serrage plus importantes que celles produites par les pièces rapportées connues à ce jour, dont les trous sont dotés de surfaces lisses.
