The invention relates to a tool for turning/turn broaching or external milling of work pieces rotating about longitudinal axes during machining, comprising a disc-shaped tool support having cassettes (20) disposed peripherally thereon, each of said cassettes containing a cutting insert (12, 13, 14), said cassettes being fastenable to a circular, partially circular or segmented removable support (11) that is fastened either directly to a machine spindle or indirectly to a machine spindle by way of an adapter. According to the invention, the cassette (20) comprises a plate seat with a seating surface (21) and two lateral surfaces (22, 23) as contact surfaces for the cutting insert (12, 13, 14) and can be radially adjusted by way of an adjustment member (27) and can be fastened by way of a clamping member (18); the cassette (20) further comprises a slit-shaped groove (30) parallel to the seating surface (21) for the cutting insert (12, 13, 14), said groove having opposing groove walls with a distance and angle with respect to one another that are adjustable by way of an adjustment screw (33) such that the angular position of the seating surface (20) can be changed.
A tool for the turn-turn broaching or external milling of workpieces which rotate about their longitudinal axis during the machining, comprising a disk-shaped tool carrier which has peripherally arranged cassettes which are each fitted with a cutting insert and which are fastened to an annular or partly annular or segmental carrier detachably fastened either directly to a machine spindle or indirectly to a machine spindle via an adapter, wherein the cassette has an insert seat having a seating surface and two side faces as bearing surfaces for the cutting insert and can be set radially via an adjusting body and can be fixed via a clamping body, and in that the cassette has, parallel to the seating surface for the cutting insert, a slot-like groove having opposite groove walls, the distance apart of which and the inclination of which relative to one another can be set by means of an adjusting screw, such that the angular position of the seating surface can be varied.
