haisstronicaCrimping Tool For Heat Shrink Connectors-AWG 22-10 Ratchet Wire Terminal Crimper-Ratcheting Crimper Tools-Available For Insulated Nylon Connectors and Electrical Wire Connectors HS-8327

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.

Wow, I am seriously impressed with this crimper!After getting this out of the included storage case, I used the heat shrink crimping jaws to crimp a heat shrink spade connector on a 16 AWG wire, and it worked perfectly the first time. Then I changed the jaws to the insulated connector jaws, and I crimped an insulated connector onto a 20 AWG wire, and it worked perfectly the first time. That is two for two, on two different style crimp connectors, with excellent crimp quality and holding power! I have never had that type of success with any other crimpers I have used.I'm definitely looking forward to continuing to use these, and expect that they will work very well for my occasional wiring needs.Changing the jaws was pretty quick and easy with a screwdriver. However, one slight challenge I had with that, is lining the top and bottom insulated connector Jaws up with each other. I say slight challenge, because it really was just a small challenge/inconvenience. If I seated both the jaws fully into the crimper, then the two jaws weren't perfectly aligned with each other. What I did to remedy that, was simply to tighten down the bottom jaw, and then align the top jaw with the bottom jaw before tightening it down. No big deal, and seem to work very well.This is a good one, just like the many other positive reviews show!

Very nice. High quality you can right when you grasp it, The ratcheting action is very smooth. Did two quick open barrel crimps and both turned out flawless. Between the grips, ratchet action and the weight of the crimper, it is a pleasure to use.The only other thing I can mention is the connector does get stucj in the jaws after the crimp. Not a proplem for me as I have a tiny pair pliers that I use to pop them out. I'm assuming this speaks to the quality of the die sizing with the crimps coming out perfect. I don't think I would as good a crimp with sloppy / looser tolerance die.Thank you Haisstronica for making a great tool at a great price... good job!

Wire crimping is definitely one of those tasks that requires the right tool for the job. Too often I see poorly crimped wire connections and I absolutely hate using insulated crimp connectors in all their color-coded forms, except when installing a CB radio or 8-track player in a car.This Haisstronica Crimping Tool exceeded my expectations in creating "factory finish" connections on the non-insulated connectors I used on a 1959 Chevrolet Bel Air. I practiced one time on a sacrificial connector to ensure that the next crimp (on the only connector I had for the application) would be perfect, which it was! If perfection is your creed, this tool will satisfy. Of course, you must use the correct connector for the gauge of wire your using and the business end of the tool is clearly marked which slot to use. The ratcheting mechanism will allow you to firmly hold the connector in the tool, then insert the wire before completing the squeeze.

Bought one to replace a cable on my RV. The price seemed good and I could return if necessary.The product was adequately packaged.It seemed study and well made. I liked that it’s ratcheting because of the tight space I was in. The release lever is nice because I accidentally selected the wrong size slot and had to release the jaws or I would have had to cut the wire I was repairing.Very happy with this purchase as well as the weather resistant connectors from the same company

Super happy I bought this after reading the reviews! This is a well-made crimp tool, very solid. I bought this tool because when you squeeze the handles the latch releases and opens the tool for crimping. This is a hefty (little heavy) tool and performs well. If I need to get another crimp tool, I will re-order this model for sure.

I am new to making electrical crimps, have small hands, struggled with other basic crimping tools. I figured i just did not have a grip strength. This ratchet wire crimping tool has changed everything. When i crimp with this tool, it feels effortless in comparison. I do not feel the metal handle digging into my hand. It gives me a measure of when the crimp is complete. It works well for me. I get alot more quality crimps done in less time with the confidence of it holding.
