Abstract: The present invention relates to a bucket wheel (1) for removing materials from a material composite (25), particularly of high hardness, comprising a main body (10), which extends around a bucket wheel rotational axis (11) and on which a plurality of buckets (12) having bucket cutters (13) are accommodated, said buckets being distributed on the circumference of the main body, wherein a plurality of cutting teeth (14) are arranged on each bucket cutter (13), the cutting teeth being movable on respective circular orbits (15, 16) by rotation of the main body (10) about the bucket wheel rotational axis (11). According to the invention, the cutting teeth (14) that are accommodated on adjacent bucket cutters (13) are arranged offset from one another, at least in part, such that the cutting teeth are movable on circular orbits (15, 16) offset in the direction of the bucket wheel rotational axis (11).
