The invention relates to a hob comprising a helically curved tooth profile (3), wherein a plurality of segments (14A, B) covering only a limited angle range are attached to a base body (2) for forming the tooth profile, wherein the segments (14A, B) abut each other in the circumferential direction of the base body (2), and the segments form rows (16) in the longitudinal axis (10) of the base body (2). The segments (14A, B) each comprise a segment foot (18) and a segment profile (20) disposed diagonally thereon. The diagonal arrangement of the segment profile (20) forms a coiled slope (s) of the helically curved tooth profile (3) in each segment (14A, B) and the tooth profile (3) can be built up simply by arranging the segments (14A, B) in rows in the circumferential and the longitudinal directions (10).
