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 selectively-positionable holder includes a portion for holding the tooth in a manner such at that a portion of the tooth projects from the holder and a base surface for attaching the holder to an attachment surface of the body. When the holder is positioned in one of a 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. |
