Abstract

The invention relates to a machine tool for use in tool machines, comprising a cutting element which is preferably configured as a cutting ring and at least two insert seats that are provided in the cutting element at distance to each other in the circumferential direction. The insert seats are fitted with at least one group of at least two identical insert tips that are detachably arranged therein and that have one working edge each, the effective working edges of the insert tips of one group being cut to the same nominal size. The insert tips are configured as indexable inserts, every single indexable insert of a group being associated with a defined insert seat in all possible positions of adjustment, and the indexable inserts of a group having at least two working edges each, one of these edges being always in the effective and at least one other edge being in the ineffective position, depending on the position of the indexable inserts in the associated insert seats. The indexable inserts of a group assume identical positions of adjustment in which defined working edges of every indexable insert of a group have the same orientation in the associated insert seat, the working edges of the indexable inserts of a group being cut to a nominal size in all common positions of adjustment.
