A method of producing a polycrystalline silicon rod is by depositing silicon on a carrier rod and cutting to size a molding produced in the process. In order that the silicon rod is given a rod end which is free of cracks and flaking, the rod is rotated about its longitudinal axis and cut through with a parting tool.
