The invention concerns a tool head for employment in machine tools with multiple indexable cutting inserts ( 20, 20', 20'' ). The tool head includes a base body ( 12 ), a tool shank ( 14 ) projecting axially beyond the base body ( 12 ) and at least two blade receptacles ( 18, 18', 18'' ) which are spaced apart at least in the circumferential direction for receiving respectively one indexable cutting insert. The active main cutting edge of the different indexable cutting inserts therein have a differing adjustment angle (alpha, alpha', alpha'') relative to the axis of the base body. In order to reduce the blade costs, the same type of indexable cutting insert ( 20, 20', 20'' ) is provided in the different blade receptacles. Besides this, the active main cutting edges ( 34 ) of the indexable cutting inserts are subdivided along their length into at least two blade segments ( 36, 36', 36'' ) in alignment with each other, wherein for the indexable cutting inserts in the various blade receptacles ( 18, 18', 18'' ) respectively only one of the cutting segments ( 36, 36', 36'' ) is effective with the associated adjustment (alpha, alpha', alpha'').
