Abstract: A tool for chip removing machining includes a holder and at least one cutting insert received in the holder. The holder is provided with at least one insert pocket, in which the cutting insert is intended to be received, and an opening connected to the insert pocket. The insert pocket has a first holding member provided along the periphery of the insert pocket, and the cutting insert has an anchor section and an edge portion connected to the anchor section. A second holding member is provided along the circumference of the anchor section. The first and the second holding members are intended to cooperate when the cutting insert is mounted in the insert pocket. The periphery of the insert pocket, at least partly, is defined by one or more circular arcs with a common center of rotation.

Abstract: The present invention relates to cutting tools and, more particularly, to cutting tools having inserts and insert-receiving recesses with curved surfaces. The cutting tool includes a toolholder having a recess and an insert adapted to be received in the recess. The recess has a top surface with a curved portion, a bottom surface with a curved portion, and a fixed stop surface. The insert has a top surface with a curved portion, a bottom surface with a curved portion, and a stop surface. The curved portion of the top surface of the insert and the curved portion of the bottom surface of the insert are curved such that they abut against the curved portion of the top surface of the recess and the curved portion of the bottom surface of the recess, respectively, when the stop surface of the insert abuts against the fixed stop surface of the recess. The present invention also relates to a cutting tool kit, a cutting insert and a method for positioning an insert relative to a toolholder.
