A tool press has at least one split die which is radially movable relative upper and lower die which are axially movable relative each other and may carry any number of associated upper or lower die punches and/or core rods. The split die has at least one die segment which moves radially between an inner position to form radially inwardly extending recesses, bores or grooves in the part during compression and an outer, expanded position which facilitates removal of a compacted part from the tool press. The upper and lower die and their associated punches and core rods may form complex profiles, such as for gear teeth, and splines on the surfaces of the part on either axial side of the split die segments, and particularly on axial end surfaces of the part, on inner surfaces of bores of the part about core rods and on axially directed surfaces of bosses formed about annular circumferential grooves in the radially outwardly directed surfaces of the parts.
