The invention relates to an insert, preferably for turning. The insert, which has a triangular basic shape, has three chip breakers in its upper flat face. A cutting edge is formed at the intersection line between a chip breaker and an edge surface. The chip breaker is formed with a conical rake face inside an associated nose portion. The chip breaker consists of an outer part and an inner part. The inner part is mainly planar and its termination at the nose portion deviates from the general direction of the inner part in order to guide and control chips during finishing. |
