摘要： A tool holder for a tool for machining a workpiece. The tool holder comprises a cutting insert receptacle for receiving a cutting insert, wherein the cutting insert receptacle comprises 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 comprises 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.

摘要： Broaching tool comprising a cutting insert having a cutting edge and a holder for holding the cutting insert. The holder has a clamping region and a holding region, wherein the holding region comprises, at its end facing away from the clamping region, a seat for the cutting insert, which is configured and arranged such that, when the cutting insert is mounted in the seat, its cutting edge projects beyond the circumferential surface of the holding region. The holding region furthermore comprises, on its circumferential surface, a support for the cutting insert. A coolant channel extends into the inside of the holder, which coolant channel comprises two exit openings which, as seen in the circumferential direction, are arranged laterally adjacent to the support and/or in lateral surfaces of the support.
