Abstract:
1. 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 a tool can be disengageably connected, wherein the tool holder is configured from modules, and at least a first module is disengageably connected to a second module, which is adjacent with respect to the longitudinal axis of the tool holder in the direction of the coupling shaft, and wherein respectively between the modules disengageably connected among one another, a centering interface is provided, which is formed by one or plural support surface sections, which are integrally disposed at the second module, which are supported at one or plural opposite surface sections, which are integrally configured at the first module, wherein at least one of the interfaces is configured, so that the first module is not radially clamped relative to the second module, or at least clamped in radially outward direction, wherein at least at one 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 holler.
