Tool holder

A tool holder for tools, in particular for drilling, turning, milling, reaming or grinding tools, comprising a longitudinal tool holder axis, and

• a shaft for coupling the tool holder to a machine tool,
• wherein with reference to the longitudinal axis, a center component is adjacent to the coupling shaft, a chuck is adjacent to the center component, and the chuck comprises a tool receiver, to which the tool can be disengageably connected,
• wherein one or plural support surface sections are integrally configured at the tool receiver, which are supportable at one or plural opposite surface sections integrally configured at the tool, thus forming a first centering interface disposed between the tool holder and the tool together with the opposite surface sections of the received tool,
• wherein the first interface between the tool and the tool holder is configured, so that the tool is not radially clamped relative to the tool holder, or at least clamped in radially outward direction,
• wherein at the first interface, a planar seat and/or a conical seat is provided proximal to the outer diameter of the tool holder,
• wherein the planar seat is configured between contact surfaces extending orthogonal to the longitudinal axis of the tool holder, or the conical seat is configured between contact surfaces extending at an angle to the longitudinal axis of the tool holder.
