摘要： The invention relates to an internal broaching tool for broaching profiles delimited by a root and flanks, said tool being suited for helical broaching. The aim of the invention is to design an internal broaching tool for broaching profiles that can also be used for helical broaching, allows broaching errors resulting from deviations from the center and/or torsional stress to be corrected in an inexpensive, robust, simple, functionally safe, and reliable manner without retroactive modification of the broaching tool, and ensures predictable, great accuracy of the shape and flanks of the profile on the broached workpiece to meet customer expectations. The internal broaching tool as per the invention is characterized in that a relief part (5) is arranged on the base (1) of the broaching tool, between the toothed part (3) and the end piece (4), adjacent to the toothed part (3) relative to the direction opposite the broaching direction, and a bush holding zone (6) is arranged adjacent to the relief part (5). Said bush holding zone (6) includes a bush contact web (7) adjoining the relief part (5), a bush entraining zone (8), a bush guiding zone (9) adjoining the bush entraining zone (8) in the direction opposite the broaching direction, and a bush mounting zone (10) located between the bush guiding zone (9) and the end piece (4). A calibration bush (12) that has calibrating broaching teeth (11) is provided in the bush holding zone (6). Said calibration bush (12) also has an entraining element holder (13) that adjoins the relief part (5) and is effectively connected to the bush entraining zone (8), several positioning elements (14) that are adjustably arranged within the calibration bush (12) in the area of the entraining element holder (13), a guiding bore (15) that is axially arranged within the calibration bush (12) and is effectively connected to the bush guiding zone (9), a stop collar (16) that is arranged at the end of the calibration bush (12) and lies opposite the entraining element holder (13), and a position securing element (17) that adjoins said stop collar (16) of the calibration bush (12) and is effectively connected to the bush mounting zone (10) of the base (1) of the broaching tool.
