Abstract

Tool holder for a tool for machining workpieces, with a tool holder body, which defines a longitudinal axis, on which a tool mount for securing a tool is formed and on which a tool holder interface for fixating the tool holder to a holder shaft is formed, wherein the tool holder interface comprises: a tool holder plane surface oriented transversely to the longitudinal axis, against which a holder shaft plane surface can abut to establish a defined relative position in longitudinal direction between the tool mount and the holder shaft, a tool holder cone section, which is polygonal in a cross-section and which can engage with a correspondingly polygonal holder shaft cone section to establish a defined relative position in tangential direction between the tool mount and the holder shaft, and a tool holder cylinder section which can act together with a corresponding holder shaft cylinder section.

Abstract

The invention relates to a tool holder (18) for a tool (30) for machining a workpiece (14), in particular for a rotary tool for turning, comprising a shaft section (24) having a clamped end and a tool end, a tool receiving section (28) which is connected to the tool end and on which a tool (30) can be secured, wherein the tool receiving section (28) defines a tool cutting plane (44) and a free surface plane (52) for a tool (30) that is to be secured thereon, wherein a feed channel (66) for coolant is integrated into the tool holder (18), wherein a coolant can be guided in the direction of the tool receiving section (28) via the feed channel (66) in order to guide a tool (30) that is secured thereon. The feed channel (66) is connected to an outlet channel (76), via which the coolant can be guided on a region of the free surface plane (52), which, at the secured state of the tool (30), corresponds to a free surface (46) of the tool (30).
