The die in the crimper I have is certainly wrong then. As mentioned above it is very flat on the bottom but the diagrams you show have a radiused bottom point

Yesterday I ordered some of these connectors as in addition to the crimp itself I was unhappy with the way the terminal located in the connector block.

How do I go about getting the correct crimper?! Ideally I would buy it on Amazon prime so I can crack on Saturday

 

This is what I bought and is in the pictures above before I was educated to all the different types! https://www.amazon.co.uk/BGS-1419-Ratchet-Crimping-Uninsulated/dp/B001ILAG2M/ref=sr_1_7?crid=1OCLI8H50JETQ&dchild=1&keywords=non+insulated+crimping+tool&qid=1591258107&sprefix=non+insulated+%2Caps%2C437&sr=8-7

 

This set looks to have the right type of dies in it and those wire strippers are an upgrade on what I have been using too

I can't seem to find just the dies for the one I have already bought

I have a crimper similar to that. Not cheap either.

When I bought it I thought it was carp. So left it in the drawer for 6 years. Then a friend - who is a electrical engineer (hands on) - showed me how to adjust the crimp pressure, using the snail cam. It's brilliant now

I have a set of Hozan P706 crimpers. They are good allrounders for many types of crimp terminal used n housings.

They are a bit spendy, but search around. I was lucky in buying a pair from a US website for around $30 and got them sent freepost to our office out there. Next time my colleague from US flew over he stuck them in his suitcase.

Ok so to round this off for anyone who was as uneducated as me on electrical terminals before all the help above.

I have learnt the following;

 

1 - Make sure the crimpers you are using are the exact right ones for the terminals or the results will be poor

2 - Buy good quality connectors/terminals

3 - Closing the terminals to a parrallel position prior to crimping helps the crimp get started correctly in the crimper

4 - Make sure you have the right size terminals for the wire specified. Thin wall vs thick wall cable also affects things here

 

I have now terminaed all the switch side into multiplugs, now got to do the other side

 

Thanks to all
