The SUMOCHAM comprises a revolutionary clamping system that enables improved productivity output rates, while enabling more insert indexes. The shank itself is designed with twisted nozzles and exhibits a durable and stable constructed body. The unique pocket design of the SUMOCHAM takes advantage of the cutting forces, which are mechanically exerted upon the tool. These forces are then converted into gripping forces that are used for tightening the insert towards the back of the pocket. SUMOCHAM head geometry features concave cutting edges that substantially enhance the self-centering capability of the drill.
The FCP head geometry is used in the oil hole, and has flat bottom configuration.
