Abrégé

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).
