Yep, that crimp tool will overcome the issues where the cable size does not precisely match the wire gauge.I'm not familiar with what is available over there, but here we have connectors with the same type of "crimp area".
The business end can be open, closed (ring), or a male or female "spade" (in 3 different sizes), bullet, and splice are the ones I can think of off the top of my head (and I have here)
In the use, there are usually 3 basic sizes for wire gauge, color coded to red, blue, yellow (small to large wire gauge)
The crimp I use basically punctures the center (not on the split side) and compresses it.
The cheap crimpers just smash these into an oval, very poor, the wires will slip out.
There is a specific tool with a "finger" that adds pressure to the crimp, but more importantly "locks" wires from pulling out.... see the "indent here"

Greg, as said earlier I use the crimps for loco work (with JST-XH connectors) and solder for track work, and again you are quite correct about prices, I paid around £20.00 for my crimps which is cheap, but they do work, looking at what "seems" like similar crimps from a professional organization - £400.00Yes Jimmy, you can really go overboard when you start using more sophisticated crimps, like most in the electronics industry, where you actually have 2 crimps per connector, one on the insulation and one on the wire.
I have about 6 crimping tools personally, and for the above mentioned crimps, you need a crimper to the EXACT size needed. To me the crimps look like a little "w". We have these at work (I run a small engineering company) and we buy the professional tools where the crimper usually exceeds $100.
But normally in this hobby, this kind of connector can be purchased with the wire already attached.
