[origin: ES8406625A1] The cutting head (1) has passages (14, 16 22) extending through the cutting head in axial direction thereof and being connected with the axial water supply bore (8) by radial bores (9). Radial bores leading to the outlet nozzles open into the passages (14, 16 22) extending through the cutting head in axial direction thereof. The passages (14, 16 22) extending through the cutting head in axial direction thereof can be closed at at least one side by means of detachable closure members (15), so that these passages (14, 16 22) extending through the cutting head in axial direction thereof can, after having removed the closure members, be cleaned by means of a cleaning-rod.
