For diameters d1 = 12 mm to 63 mm guide pillars that are around 1 mm to 3 mm smaller and which shall be used during installation in press tool sets with centrally or diagonally arranged guide pillars are respectively listed in order to achieve that the top part of the tool and the bottom part of the tool can be joined together only in the correct position.
