Whirling tool

A whirling tool, comprising:

• a plurality of cutting inserts, wherein each of the cutting inserts comprises at least one cutting edge;
• a cutting insert carrier that comprises a plurality of cutting insert receptacles that are each configured to receive one of the cutting inserts for releasably fastening therein, wherein the cutting insert receptacles are arranged so as to be distributed in a circumferential direction over the cutting insert carrier, wherein the cutting insert carrier comprises a through-opening which extends along a central axis of the cutting insert carrier, and through which the workpiece can be passed during the machining, wherein the cutting insert receptacles are arranged on a front face of the cutting insert carrier that runs transversely to the central axis, wherein each of the plurality of cutting insert receptacles comprises a supporting surface extending orthogonally to the central axis and at least two bearing surfaces that are arranged transversely to the supporting surface of the respective cutting insert receptacle, the at least two bearing surfaces of each of the plurality of cutting insert receptacles are arranged at an acute angle to one another and orthogonally to the supporting surface of the respective cutting insert receptacle, wherein each of the cutting inserts bears on the respective supporting surface in a planar manner, and wherein in a mounted state of the whirling tool the cutting inserts protrude into the through-opening;
• and
• a coolant channel which is arranged in the cutting insert carrier and which extends between an inlet opening and an outlet opening, wherein the outlet opening leads into the through-opening and/or is oriented towards the through-opening.
