Zusammenfassung:The invention provides a cutterhead for tunneling equipment and the tunneling equipment with the cutterhead. The cutter head comprises a base and a cutter. The base is rotatable about an axis of rotation along a tunneling direction of the tunneling equipment. The cutter comprises a plurality of hob sets arranged at intervals in the circumferential direction defined relative to the rotation axis, and each hob set comprises a plurality of hobs arranged in the radial direction defined relative to the rotation axis from the rotation axis. The rotating axis of the hob is perpendicular to the rotating axis of the base. The hobs in each hob set retreat by a preset distance relative to the adjacent hobs located on the radial inner side in the tunneling direction, so that the front ends of all the hobs in the hob set can be located on the same fitting arc. According to the invention, the hob forms an arc profiling fitting curve which can well adapt to the arc structure of the main tunnel segment, and is suitable for c
