A technique facilitates combined drilling and coiled tubing operations from a single bed of a rig. A mast is mounted to the bed, and a coiled tubing injector is connected to the mast. The coiled tubing injector is able to move coiled tubing into and out of a wellbore. A starter head also is mounted to the mast. The starter head is rotatable to make and break connections of tool string components. However, the starter head generally is rotationally stationary during drilling operations.
