A tool holder comprising:
- a first section adapted to be connected to a machining center;
- a tool holding section for receiving and holding a shank of a tool therein, wherein the tool holding section comprises of
- a solid body with an axis of rotation extending there through;
- an outer diameter surface around the solid body;
- a front face perpendicular to the axis of rotation;
- a retaining bore centered on the axis of rotation and extending from the front face into the solid body for receiving and holding the shank of the tool therein;
- and
- a plurality of defined contact surfaces each partially protruding in the retaining bore for directly engaging the shank of the tool for holding the shank of the tool in the retaining bore at the defined contact surfaces.

A method for creating a shrink-fit tool holder for retaining a shank of a tool, the method comprising:
- forming in a front face of a tool holding section centered on a rotational axis a retaining bore for holding the shank of the tool;
- and
- forming in the front face of the tool holding section of the shrink-fit tool holder a plurality of defined contact surfaces each partially protruding in the retaining bore for directly engaging the shank of the tool for holding the shank of the tool in the retaining bore at the defined contact surfaces.
