A process for powder metallurgic manufacture of a coupling body (1) with a crown (2) of coupling teeth (3) is described, whose flanks (5) going out from wedge-shaped end faces (4) are in relief, such that a formed body with coupling teeth (3), which have wedge-shaped end faces (4), but flanks (5) parallel to axis, is pressed out of a sintering powder and sintered to a molded blank, whose coupling teeth (3) for forming the flank reliefs are subjected to axial compression molding between two form tools (9, 10) on the one hand for the wedge-shaped end faces (4) and on the other hand for the flank reliefs. To create advantageous processing conditions it is suggested that during compression molding of the flank reliefs in the transition region between the flanks (5) and the wedge-shaped end faces (4) a flank-side interlocking shoulder (7), with a rounded transition (8) to the wedge-shaped end faces (4) and lying in the mold surface (11) of the form tools (9, 10), is pressed into the flanks (5) of the coupling teeth (3).
