    Abstract: An apparatus, rock drilling rig and method for rock drilling includes a turning device for moving a drilling tool around longitudinal axis of the tool. The turning movement is controlled by an alternating turning system so that direction of turning movement is continuously reversed to first and second turning directions. The turning angle of the tool is restricted and a safety system (is configured to monitor the operation and to ensure that a predetermined turning angle is not exceeded.
