Die stock

A holder for a die stock, wherein the holder:

• is substantially cylindrical and is symmetrical to a holder longitudinal axis that runs in an axial direction,
• has a plurality of receiving grooves, wherein each of the receiving grooves extends from a first end face of the holder in the axial direction, said first end face running transversely to the axial direction, and wherein each of the receiving grooves extends from an inner side of the holder in a radial direction, said inner side facing toward the holder longitudinal axis,
• a plurality of clamping wedges arranged detachably in the receiving grooves in order to axially and radially fix cutting inserts, wherein one clamping wedge is provided for each of the receiving grooves, respectively, wherein the clamping wedges may in a peripheral direction be arranged alongside the cutting inserts in each of the receiving grooves, respectively, said peripheral direction running transversely to the axial direction and the radial direction, and
• one holding means per receiving groove, for fastening the clamping wedges in the receiving grooves.

A set of a plurality of cutting inserts for a die stock, wherein the die stock has a substantially cylindrical holder, which is symmetrical to a holder longitudinal axis that runs in an axial direction, and has a plurality of receiving grooves each of which is configured for receiving a clamping wedge, wherein each of the receiving grooves extends from a first end face of the holder in the axial direction, said first end face running transversely to the axial direction, and wherein each of the receiving grooves extends from an inner side of the holder in a radial direction, said inner side facing toward the holder longitudinal axis, and wherein the die stock has one holding means per receiving groove, for fastening the clamping wedges in the receiving grooves, wherein the individual cutting inserts of the set:

• each have on a front side at least one cutting edge and orthogonally to the axial direction a cross-sectional profile which, starting from the front side, widens along the radial direction outward in a wedge-shaped manner,
• have different cutting edge geometries, such that the cutting edges of the cutting inserts form different peripheral segments of a thread, and
• each are axially and radially fixable in one of the receiving grooves of the holder by means of one of the clamping wedges and, in a peripheral direction running transversely to the axial direction and the radial direction, can be arranged alongside one of the clamping wedges in one of the receiving grooves.
