Title: CUTTING INSERT, TOOL HOLDER, AND TOOL FOR MACHINING A WORKPIECE
Abstract:
The invention relates to a cutting insert (12) for a tool (10) for machining a workpiece, comprising a cutting edge (22) and a cutting insert bore (32). The cutting insert (12) extends along a cutting insert longitudinal direction (18), and the cutting insert bore (32) extends along a bore axis (36) which runs orthogonally to the cutting insert longitudinal direction (18). The cutting insert (12) has a laterally protruding elevation (30). A lateral holder contact surface (40a), an axial holder contact surface (42), and a horizontal holder contact surface (44a) for bringing the cutting insert (12) into contact with a tool holder (14) are arranged on the elevation (30). The lateral holder contact surface (40a) runs orthogonally to the first bore axis (36), and the axial holder contact surface (42) and the first horizontal holder contact surface (44a) run orthogonally to the lateral holder contact surface (40a) and transversely to each other. The invention further relates to a tool holder (14) with a receiving area (54) for the cutting insert (12), said receiving area (54) being provided with a depression (56) which has contact surfaces (56, 58, 60) that correspond to the contact surfaces of the cutting insert (12), and to a tool (10) composed of the cutting insert (12) and the tool holder (14).
