In a hewing or cutting roller (1) of variable cutting width, in which two pivotable tool carriers (4, 5) for receiving cutting or hewing tools are arranged on at least one lateral end face (2) of the roller transverse to the axis of the hewing or cutting roller (1), one of the tool carriers carries a locking pin (10) which cooperates with a hook-shaped locking member of the other tool carrier in the extended position of the tool carriers (4, 5). |
