haisstronica 6PCS Crimping Tool Set - Ratchet Wire Crimping Tool for Heat Shrink,Insulated Nylon,Non-Insulated,Ferrule Wire End,Open Barrel Terminals,Solar Connectors

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!

I've noticed the newer crimp connectors with heat shrink sleeves don't seem to crimp as well with the old type of crimp that leave a narrow crimp mark. I thought I would try this since I bought an assorted set of the connectors with the shrink tubing. I'm not disappointed. The wider crimp seems to be working well as it is securely holding the wires in the connector where I could pull the wires out of the connector with the old style crimper. I'm not sure if it's a material difference in the connectors. They do seem much thinner than the old non-shrink sleeve versions. I'm please with the performance of this tool. The different heads are great because I do crimp different styles of connectors, i.e insulated and non-insulated terminals.

Used this set for the first time Sunday. I found that I liked it more than I thought I would have.The only small negative is that there is no chart included to tell what each die set is used for. Not a big problem, printed the picture from the Amazon listing.Nice quality!

Wire crimping is definitely one of those tasks the 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.

I like the performance of the haisstronica 6PCS Crimping Tool. I used the butt connector anvils to crimp some heatshrink-style butt connectors on 18 and 16 AWG automotive wire. The anvil's design preserves the integrity of the insulation around the butt connector so the electrical conductors stay dry under my truck.The ratcheting action ensures a full mechanical crimp and allows you to pre-clamp the connector in the jaws and insert the wire after, just before the final crimp. This helps when crimping in tight spaces.The tool is big. I had some trouble fitting it into the cramped spaces where my chassis wire bundles run under my truck.

It's worked perfectly so far with all of the crimps I've had to make. I used it to crimp some 110 type spade connectors for a wiring harness and this comes with the correct crimping jigs to replicate the original ones on the wiring harness.
