Tool holder

A tool holder, comprising:

• a base element,
• a clamping chuck being a shrink fit chuck comprising a deformable receiver for clamping a rotation tool, the deformable receiver comprising a sleeve received within a receiver opening and configured to be heated to expand thermally allowing an inner diameter of the receiver opening to be enlarged for receiving the rotation tool, and at least one locking element integrally configured with the receiver which locks the rotation tool against an axial migration of the rotation tool out of the tool holder;
• and
• a shaft of the rotation tool having at least one locking groove and including a circumferential surface and an end face, wherein the at least one locking element is held in a support bore hole by one of a threaded pin or by press fit, or the at least one locking element is configured with an exterior thread, which is configured corresponding to an inner thread configured in the support bore hole, wherein the at least one locking element engages the at least one locking groove, wherein the at least one locking groove begins at the end face of the shaft, and wherein the at least one locking groove extends into the circumferential surface and is L-shaped, curved, or Includes composite paths where the composite paths are linearly offset from one another.
