Zusammenfassung:	A tool holder for a tool for machining a workpiece. The tool holder has a cutting insert receptacle for receiving a cutting insert, wherein the cutting insert receptacle has an upper clamping jaw for abutting an upper surface of the cutting insert and a lower clamping jaw for abutting a lower surface of the cutting insert opposite the upper surface. Further, the tool holder has an internal coolant channel extending inside the tool holder between a coolant inlet opening and a coolant outlet opening, wherein an end portion of the coolant channel extending inside the upper clamping jaw along a channel center axis opens into the coolant outlet opening. The coolant outlet opening is arranged at the upper clamping jaw and configured as an elongated opening. A width of the coolant outlet opening is smaller than a height of the coolant outlet opening measured orthogonally to the width of the coolant outlet opening. The end portion of the coolant channel is also elongated in a cross-section orthogonal to the channel center axis. A width of the end portion measured orthogonal to the channel center axis is smaller than a height of the end portion measured orthogonal to the channel center axis and orthogonal to the width of the end portion.
