Abstract
A groove cutting tool has a groove insert and a tool holder. The groove insert can be replaced by using a lever tool. The lever tool penetrates into a slot by way of an ejector portion and is able to assume several positions in the slot either in order to contact the groove insert and to push it out of its receiving means or in order to push away a clamping jaw and to open the receiving means for the groove insert.
