A hob having a helically curved tooth profile. A plurality of segments covering only a limited angle range are attached to a base body for forming the tooth profile. The segments abut each other in the circumferential direction of the base body, and the segments form rows in the direction of the longitudinal axis of the base body. The segments each comprise a segment foot and a segment profile disposed diagonally thereon. The diagonal arrangement of the segment profile forms a coiled slope of the helically curved tooth profile in each segment and the tooth profile can be built up simply by arranging the segments in rows in the circumferential and the longitudinal directions. |
