<p>The invention relates to a chisel, in particular for a drill head and/or cutting head, having a chisel head (10) and a chisel shank (30) attached directly or indirectly thereto; the chisel shank (30) has a first receptacle region (32), to which a first tensioning element (40) is assigned. An optimal design of such a chisel with regard to wear can be attained in that the chisel shank forms a second receptacle region (35), which has a reduced cross section relative to the first receptacle region and to which a second tensioning element (50) is assigned, and that the chisel shank (30) is rotatable relative to the first and second tensioning elements (40, 50).</p> |
