haisstronica Crimping Die for Open Barrel Terminals,22-10 AWG

This is a solid crimping tool and absolutely worth the price. It feels sturdy in the hand and works far better than the old all-in-one stripper and crimper I used before. The ratcheting action makes each crimp consistent, and hearing the clicks as it tightens down gives you confidence that the terminal is fully secured. It is also more versatile than I expected. The markings on the jaws make it easy to choose the right size, and the tool handles different non-insulated terminals without slipping or deforming anything. I used it for replacing furnace terminals and every connection came out tight and clean. The instructions are simple but helpful, especially if you have never used a ratcheting crimper before. Just make sure the open ends of the terminal rest on the flat side of the jaws before closing. Once you get used to that, it becomes a quick one-hand process. For the price, the build quality, ease of use, and consistent results make this a strong value.

The Haisstronica Crimping Tool for Non-Insulated Open Barrel Terminals has several features that make it a quality tool. This specific model covers 10- through 20-gauge 2.8mm terminals. That size covers many of my applications, e.g., automotive and electronics. The jaws are replaceable, so the basic ratcheting pliers can be configured for different styles of terminals. The jaws are marked in square millimeters and AWG. On the side of the tool is a cogged wheel to adjust the clamping force. It is adjusted by removing a screw, rotating the wheel, and reinstalling the screw – a little inconvenient but it prevents inadvertent changes to the clamping force. The ratchet mechanism has a lever to open the pliers. The pliers will open automatically when the crimp is completed, but should the pliers remain closed, the lever can be tripped to release the jaws. The gap is small for an adult finger, but any sort of probe could be used to operate the release lever. The handles are well-made with good-sized, comfortable grips. Using the crimper is easy – strip the wire insulation back about 1/4 inch, insert the terminal into the crimper (flush on the left side with the tabs facing up) and squeeze enough to hold the terminal in the jaws, insert the wire into the terminal to the required depth, and squeeze the crimper handles until they release and the jaws open. A final inspection of the quality of the crimp is the final step. If the tabs on the terminal are nicely formed over the wire insulation and core, and the terminal passes a rudimentary pull-test, you have a quality terminal crimp. My first two crimps were just fine at the “factory” pressure setting. No need to mess with that adjustment. This is an excellent crimper, especially at the price -point. Good luck with your crimping.

Does a really good job. Used it to attach 20 ga stranded wire to spade lug connectors. I wasn't prepared for how much strength it took to do the crimping, but the device is "ratcheted" so if you pause you can continue on until the crimp is done. I remember the cheap stamped crimping tools were easier to use, but when you compare the quality and ruggedness of the crimp, it's easy to see how much more robust this tool makes the attachment of the wire to the lug. One thing I noted - when you think you are all crimped, if the tool hasn't gone "over center" you're not done. By "over center" I mean that after applying a lot of force to close the jaws, the tool suddenly gets much easier to press and the handles come together completely. Up until that point you haven't finished the crimp. For verification, I used an ohmmeter to check the connection; not only are the lugs well attached to the wire with a little pull-test, they are electrically good as well. No one wants to be searching all over for a bad connection, or have one of the lugs come loose from the wire when you put a little strain on them. I haven't tried connecting larger wire so I can't say how much pressure would be required; the 16ga to 22ga part of the jaws is on the outermost part of the tool, so it may well require the most effort to use. So while I was surprised by the work it takes to use this tool, I have decided that is due to the thicker jaws making a broader crimp, compared to the cheap sheet-metal crimpers, resulting in a very good connection. For that I give the tool five stars.

Does a great job crimping and seems well made, I have wanted one for a while to use for car audio, The jaws switch out very easy and have a sturdy grip. There are two reasons I gave 4 stars, 1- sometimes the jaws get stuck if you close them 3/4 to hold the splice and insert the wire, you have to release and do a full pull. They may just need adjustment. 2- You have to reference the included paper to know what jaws to use, it would be nice if the case or jaw was labeled.

The Haisstronica Crimping Tool is outstanding! It’s sturdy, comfortable to use, and delivers consistent, professional-quality crimps. The ratcheting mechanism feels smooth and secure, and the adjustable tension makes it easy to get just the right amount of pressure. Paired with heat shrink connectors, it creates strong, clean connections that look great and hold tight. The ergonomic handle reduces hand fatigue, even after long use. This tool has quickly become one of my go-tos for electrical work,excellent quality at a great price!

Great crimper for electrical connectors. Used on stranded 10 gauge and it worked perfectly. Ratcheting component made crimping easy. Ratchet released once crimped.

Really good crimper. Did a big project with many crimps using mostly yellow, but also blue and red. All crimped perfect and held good. Crimper always automatically released for me as well.

Perfekt, fyller sin funktion väl

Buon prodotto ma non adatto al lavoro, per uso privato ok

Die Crimpzange macht einen soliden und wertigen Eindruck. Erste Ergebnisse im Einsatz waren gut.

Excelente producto en calidad y precio

Handig om thuis te hebben. Werkt prima met alle maten vlak stekker/-hulsen.
