The invention relates to a calibrating plate for an extrusion die for producing plastic profiles, comprising a substantially plate-shaped basic body ( 21 ), in which an opening ( 22 ) for guiding and calibrating the plastic profile ( 23 ) to be produced is provided, with at least one insert part ( 1 ) made of a material with high hardness being inserted into the basic body ( 21 ), which insert part comprises at least one holding section ( 2 ) and a shaping section ( 3 ), with both the holding section ( 2 ) as well as the shaping section ( 3 ) being formed partly as cylindrical surfaces with generatrices parallel to the extrusion axis ( 6 ), and with the insert part ( 1 ) being held in the axial direction in the plate-shaped basic body ( 21 ) by a delimiting stop ( 5 ). A longer service life and a simpler adjustment can be achieved in such a way that the holding section ( 2 ) comprises a groove ( 4 ) which extends in the direction of extrusion ( 6 a), and that the delimitation stop ( 5 ) is arranged at one end of the groove ( 4 ), which stop protrudes from the groove ( 4 ).
