Any good tools for crimping larger wire sizes 2.5mm2 -> 4.0mm2 (AWG13 -> AWG11) on JPT/SPT/BDK terminals with wire seals?

I have the Iwiss 1424B tool (similar to the tool in the tools recommendation thread), it's supposed to be for weather pack but works well up to ~2.0mm2 for conductor and wire seals on most openn barrel variants.


I also have one of the tools that do the conductor and wire seal in a single step that accpets up to 6mm2 but the crimp quality is not that impressive
