摘要： The present invention provides a holder for holding a tooth on a body of a cutting blade or grinding drum for cutting or grinding rock or hard earth formations. The body has an attachment surface for attaching the holder. The holder comprises a portion for holding the tooth in a manner such that a portion of the tooth projects from the holder. The holder also comprises a base surface for attaching the holder to the attachment surface of the body. The holder is positionable in a plurality of different orientations in which the base surface is attachable to the attachment surface and in which the received tooth projects from the body in a predetermined direction. When the holder is positioned in one of the plurality of orientations, the base surface has, within an area over the attachment surface, a shape which is profiled so that a region defined between the base surface and the attachment surface is, for at least one of the plurality of different orientations, smaller than a region that would be defined if the base surface would have a flat shape.
