A tool unit is attached, welded in particular, to a drum surface (11) on a milling drum tube (10) for a rock-digging machine, e.g. a surface miner, a road-milling machine or the like. The tool unit has a base part (20) set up with a concave bearing section (24) and welded on the drum surface. The base part has a tool holder, into which a chisel/cutter (30) is inserted, especially a straight-shank/parallel chisel/cutter, which has a chisel/cutter head linked to a chisel/cutter shank. |
