I want to talk a little bit about Hozan P-707
crimp tool, that I ordered from Japan.
If you are looking to purchase this tool you can find it on Amazon or eBay
I know that many people use similar, universal tools from Engineer, but this tool proved to be quite interesting
This crimping tool can be used to crimp both male and female versions of different terminals, onto 14-30 AWG
wires. 15 various-sized dies make this product suitable for a wide range of terminal sizes, from small to large.
A list of P-707 compatible terminals is posted on Hozan website.
Crimp jaws are divided into two parts, the right for crimping wires, left (closer to the edge of the tool) for crimping insulation.
Using this crimp tool, you need to crimp the terminal in two separate operations: first you crimp the conductor and then you crimp the insulation.
That also allows for more flexibility in the choice of wire if the insulation is of difference diameter.
The crimping dies has a different thickness depending on the size (narrow for small wires/terminals, wider for larger wires/terminals)
CRIMPING OF VARIOUS TERMINALS
This crimp tool does a pretty good job of crimping Molex KK 254
and JST PH 2.0 (female)
Mini-PV (DuPont) male terminal
This crimp tool have round insulation die (1.6mm round insulation crimp) and it works just fine with DuPont terminals.
Molex Mini-Fit Jr.
Wire size: OD=2.0mm
I'm afraid things aren't looking good here.
You will come across a problem if you use a wire OD=2мм and terminals with long wings.
This tool tends to bend one wing of the terminal before the other, so two wing will overlap (overlap insulation crimp) instead of meet in the middle and crimp downward.
Similarly crimps the tool from Molex, but it has crimp dies with an "overlap" profile on all pockets. Here we have a symmetrical, not deep profile and as a result we obtain a one-sided deformation (material extrusion in corner) of the terminal. This is wrong, but's not critical.
I used different dies for crimping insulation..
2.4mm - It has a small size as result- is a ruined terminal
2.9mm - one-sided deformation, acceptable result
3.5mm - it's a big size, we get a flattened terminal
the optimal size : 2.8-2.7mm .. but we do not have it in this tool.
Wire size: OD=2.3mm
When using AWG16 wire (OD=2.3mm), the result will be better, but it will not be ideal.

Does a great job of crimping Molex 8980 terminal:
Molex Serial ATA terminal 67581
similar result as with Mini-Fit Jr. terminals (see above).
- high quality materials.
- well made and accurate jaws.
- marking on both sides of the jaws
- elastomer grip
- very versatile crimper for many different terminals
- you can more reliably crimp with a light force by the toggle mechanism adopted
- you'll be able to make crimps identical to factory ones (after little practice)
- non- ratcheting, so you can apply just the right amount of pressure.
- this currently costs from 6,260JPY in the Japan, maybe overpriced.
- manual not included
