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 stably constructed body.
The unique pocket design of the SUMOCHAM takes good 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.

The head geometry features concave cutting edges which substantially enhance the self-centering capability of the drill.
