Testing Crimp Tools
I have a quick test for a prospective crimping tool. I prepare a stranded, copper wire and crimp it with a FULL closure in the appropriate connector. I then grab that connector in a vise and pull on the wire until it fails - until it separates from the connector. If the wire breaks, with pieces of some or all the strands still in the connector, the tool is OK. If the wire just pulls out of the connector, with NO broken strands, then the tool is rejected. I have returned tools to the supplier based on this test.
In my professional career as well as my personal projects, I have never had a problem with a tool that passed this test. But I am careful when making crimp connections.
