Hozan P-707 Crimping Tool (for Open Barrel Type Contacts), Crimping Pliers, 15 Types of Large and Small Dies, Compatible with a Wide Range of Terminals

This is the best crimper I have used. It is well designed and easier to get good crimps with than any of the other brands I have tried. For example, this crimper has separate areas for crimping the wire and the insulation which have different shapes and are optimized for what they are intended for. This makes it easier to use than most other crimpers. Other crimpers do not have this feature.

I'm finicky about electrical connections on vehicles. I've outgrown the colored insulated crimp-on terminals. I want my all my wiring to look like OEM spec. This is probably the least you can spend to get a tool that will make dependable open barrel crimps. If you look closely at the crimping dies on the Chinese generic crimpers you will see that they are rather crudely made. The Hozan dies are accurate formed. It takes a little practice to get your crimping protocol down so order a lot of quality terminals to practice on. I get the AMP/TE Connectivity ones from a large electronic supply house. With this crimper it is a two step process. First insert the terminal in the crimper and crimp the stripped wire into the terminal. You can control the amount of pressure you use. If done properly the open "ears" of the terminal are now formed into a soft "M" shape over the bare wire and a small dimple is usually indented on the back of the terminal. Give a light tug on the wire to make certain you have crimped enough. Then I move to a larger notch or die in the crimper and fold the open ears over the insulated wire for strain relief. You apply enough pressure to firmly grip the insulation but not enough to cut through the insulation to contact the bare wire. I finish up with heat shrink over the exposed metal of the terminal outside the contact points. I hope this makes sense and is of help to you. With practice you can come up with cleanly done, dependable terminals for your projects.

I bought these specifically for knock off DuPont connectors at the advice of an online site and it gradually took over all open barrel crimps I do. I have good quality expensive multi-die crimpers that do insulator and conductor crimps at the same time and numerous cheap (< $100) pliers type crimpers. The P-707 just does the job better. I don't really notice the lack of ratcheting but I do have giant hands so that may be why. The force required isn't particularly high. The few bad crimps I've had out of hundreds were all my fault for letting the wire get out of position.

Good crimper for general wiring. The jaws could be a bit wider, but that is just a nit. Happy with it.

Dupont crimp terminals are shaped to be crimped into a circular form. Every cheapo tool out there crimps them oval, except this one. Worth it for this alone. Works as well as the official factory tool.

Yes yes it is true, this crimper is of incredible quality and will probably provide the best crimps for the price, BUT. It just isn't designed that well. Issue 1: The crimp direction for the conductor crimp and the insulation crimp are reversed so you have to flip the crimper around twice to crimp one terminal. Issue 2: I have medium sized hands and I have just enough extension on my fingers to use this thing, if you have small hands you, you are not gonna like this thing. Issue 3: Force requirement, This crimper requires a disproportionate amount of force input to the crimp strength received, after about 50 crimps my hands are pretty tired, not even pulling the clutch on my 650 dual sport all day is as tiring as using this crimper. The only benefit I see with this crimper is precision. I figured out how to get nice crimps for DuPont clones on my 25$ crimper after buying this one, and given that the cheap crimper is quicker, easier to handle, and requires less force, I honestly am going to start using that cheap Chinese one over the Hozan. To get good crimps on the cheap crimper what I do is crimp normally, them bring the small end of the crimper over the insulation crimp and crimp 3x. Using the Hozan and the method I mentioned above the wire breaks before I am able to pull the crimp off so I am going to say it: The hype around the Hozan crimper is old electronics guys in their 40s+ oogling over nice Japanese build quality and properly formed dies when really it doesn't matter that much and the crappy 25$ crimper can be just as good if not better if you get a bit creative withit.

Great set of strippers, I have 2 at this point

I ordered this tool along with other Hozan crimpers/strippers in order to perform electrical repairs on motorcycles and/or vehicles. I researched long and hard for a tool that could produce factory quality (OEM) crimps on electrical connections. I would have to say this tool does just that, precisely! I'm convinced its the tool they use on Japanese motorcycles, considering it is a Japanese brand. I have other crimpers/stripers from other US brands, specifically Snap-On, Blue-Point, Klein, KD, etc., while great in quality & performance, they just don't perform as well as this brand. I recommend this tool & brand to any one who wants to perform professional electrical crimps.

Got it all, easy to use, wide variety of sizes and well made.

Great for crimping most automotive terminals, significantly better than traditional crimpers as the design of these fives you increased mechanical leverage but not ratcheting means that you can apply exactly the required amount of crimp force required for each terminal. It's large but the fact that it does so many terminal sizes means it saves you from carrying around multiple sets of crimpers. For the at home automotive enthusiast looking to do small amounts of re-wiring of their vehicle it is a very smart purchase. Quality looks great as well being Japanese made.

As decribed and very good to use

Thought I would try one of these so as to have more sizes of crimpers available to me. Basically, the Engineers Pad-13 I already have is a lot better; easier to grip and gives a nicer result.

クリンプハイトの調整ができないので、強くカシメすぎると導線が傷んで断線しやすくなってしまいます。適切に力を下限すれば良いのですが、安定した一定の品質を保つことは困難です。ちょっとした実験用とかには便利で良いと思いますが、売り物は作れません。
