<p num="1"><br/><br/><br/>The present invention provides a holder for holding a tooth on a body of a <br/>cutting blade or grinding drum for cutting or grinding rock or hard earth <br/>formations. The body has an attachment surface for attaching the holder. The <br/>holder comprises a portion for holding the tooth in a manner such that a <br/>portion of the tooth projects from the holder. The holder also comprises a <br/>base surface for attaching the holder to the attachment surface of the body. <br/>The holder is positionable in a plurality of different orientations in which <br/>the base surface is attachable to the attachment surface and in which the <br/>received tooth projects from the body in a predetermined direction. When the <br/>holder is positioned in one of the plurality of orientations, the base surface <br/>has, within an area over the attachment surface, a shape which is profiled so <br/>that a region defined between the base surface and the attachment surface is, <br/>for at least one of the plurality of different orientations, smaller than a <br/>region that would be defined if the base surface would have a flat shape.<br/> |
