  1. Operating temperature for thermally stable blanks should not exceed 1562°F (850°C). Operating temperature should not exceed 1202°F (650°C) for all other blanks.
  2. Maximum recommended diameters for new dies are advised by die blank supplier
  3. Maximum recommended diameters for recut dies are calculated for 21% wire elongation with the following geometries:
    - soft wire: reduction angle: 18°, bearing length 30%
    - hard wire: reduction angle: 12°, bearing length 30%
  4. Other casing dimensions are available on request
