Zusammenfassung:	A method for the powder-metallurgic production of a rod-like body (1) from hard metal, cermet or ceramic by the extrusion of a starting material and sintering is provided. The starting material is extruded such that at least one first channel (3) is formed. Before sintering to achieve the final density of the rod-like body (1), the rod-like body (1) is mechanically machined in order to form at least one further recess (6).
