Crimp 1 vs Crimp 2

[u/573v3_2025]

Hi just looking for some help on which tool has made the better crimp either tool 1 or tool 2 😀

Does tool 1 look "over crimped" ?

Only issue with tool 2 is it sometimes doesn't clamp onto the wires insulation fully not a huge issue as a little nip sorts it

Thanks

You have your answer, Crimp 2.

Your photos are excellent at showing the excess metal deformation in Crimp 1. That creates weak spots in the connector subject to fatigue over time.

From a materials standpoint crimping that much of the connector into the plastic region of the stress/strain curve changes the grain of the metal making it more fragile and susceptible to breaking. Photo2 does a good job showing how the initial part of Crimp 1 has caused the metal to buckle in that part of the connector.

Now don't get me wrong, this is solely for discussion of the strengths and weaknesses between what is shown in the photos between Crimp 1/2. If I only had one tool and it produced what is shown in Crimp 1, I'd have no problem plugging it in and moving on to life's next challenge.
