The disclosure relates to a die stock comprising: an annular holder having a plurality of receiving grooves; a plurality of cutting inserts; and one fixture per cutting insert for axially fixing the respective cutting insert in one of the plurality of receiving grooves. The plurality of receiving grooves are provided on an inner periphery of the annular holder and run in an axial direction parallel to a central longitudinal axis of the annular holder. Each of the plurality of receiving grooves has a receiving groove profile for receiving one of the plurality of cutting inserts. Each cutting insert is received within a respective one of the receiving grooves and comprises at least one cutting edge that is arranged on a cutting surface that faces toward the central longitudinal axis of the annular holder, wherein each cutting insert comprises a holding profile that is arranged on a holding surface opposite the cutting surface. The receiving groove profiles of the receiving grooves and the holding profiles of the cutting inserts interact with each other in such a way that a cutting insert, when inserted into its receiving groove, is guided in the axial direction parallel to the central longitudinal axis of the annular holder and, in the fully inserted state, is clamped in a radial direction perpendicular to the central longitudinal axis of the annular holder. |
