Activated by a vinyl ball, a pre-calculated percentage of drilling fluid passes through the tool to the BHA and drill bit below. At the same time, three field-interchangeable jetting nozzles on the side of the tool are directed up-hole to give increased annular fluid velocity, maximised hole cleaning and minimal well bore erosion. The tool can be cycled to provide split flow up to 10 times.
