The tool further a control device for directing the water into either drilling nozzles or cutting nozzles depending on the rotational position of the control device. A switching element driven by water pressure engages the control device to cause the control the device to rotate from one rotational position to another rotational position, thereby changing the tool from cutting to drilling or vice versa.
