Way too small for any 100 size crimp F I've ever seen.

Does anyone know the correct Die size .. ? or could take a look at their
CT100 tool.

The best answer is to ask the connector manufacturer (or vendor) who
_should_ know. Typically though the answer will tend to be either 0.324
in. (~8.2 mm) or 0.360 in. (~9.1 mm), the former being common for the
cheaper crimp F plugs and the latter for the better quality ones (e.g.
Cabelcon).
