The invention relates to a device for accommodating objects, in particular receptacles in which tools or tool parts are sorted and kept, on a bottom part in particular of a drawer. The device includes at a proximal portion a holder portion that is adapted to be fitted to a drill string engagement element of a rock drilling machine. A mold-core carrier is constructed with tapered sides that hold the assembled mold and core elements together during pouring of the molten iron alloy into the mold-core assembly and the cooling period to form the casting.
