Abstract

A parting blade includes an internal cooling agent supply and has two substantially plane-parallel lateral faces and a continuous transversal bore connected to a cooling agent channel that runs parallel to the lateral faces in the interior of the parting blade. In order to provide a parting blade that has no projection on one side, a stopper is provided having two substantially parallel end faces and a circumferential face that connects the end faces. The stopper can be inserted into the transversal bore of the parting blade, thereby sealing the transversal bore relative to at least one lateral face of the parting blade. The stopper terminates without protruding over the sealed lateral face, flush with the lateral face. The stopper has an opening on both the end face and the circumferential face. The openings are connected to one another in the interior of the stopper to connect the cooling agent channel to a cooling agent source.
