Abstract: The invention refers to a tool (1), a machine tool, and a method for cutting machining of a workpiece. The tool includes a mounting portion (5) for mounting of the tool in the machine tool, a tool shaft (7), which has a first inner end (7?), connected to the mounting portion (5), a longitudinal center axis (a), which extends through the mounting portion and the tool shaft, and a main cutting edge (9) on the tool shaft. The main cutting edge (9) has an extension in an axial direction along an imaginary envelope surface, which is concentric to the center axis (a) and located radially outside an outer periphery surface of the tool shaft (7). The main cutting edge (9) is arranged to permit cutting engagement with said workpiece when the tool is rotated around the longitudinal center axis.
