Zusammenfassung:	The invention relates to a cutter head (1) for removing material from a water bed. The cutter head (1) is arranged to rotate about an axis of rotation (RA). The cutter head (1) comprises a base ring (10) and a hub (20), the base ring (10) and the hub (20) being positioned rotational symmetric with respect to the axis of rotation (RA). The cutter head (1) comprises a plurality of arms (30) extending between the base ring (10) and the hub (20), the arms (30) comprising a plurality of excavating tools (40). The excavating tools are provided by bits (40) having rotational symmetric bit ends (41), wherein the arms (30) comprise one or more groups of bits (40), each group comprising three or more adjacent bits (40) of which the bit ends (41) define a straight line segment (LS).
