Taiss Dupont Crimping Tool Kit Ratcheting Wire Crimper with 2.54mm 600PCS Dupont Connectors and 560PCS JST XH Connectors,Dupont Crimper,JST Crimper(0.08-0.5mm² 28-20AWG)

Crimping anything correctly is time consuming and takes patience. If thinking of buying this to save money making your own single-wire Dupont connectors, just buy the premade ones instead. Where this kit shines is custom wiring with various length, conductor count, and M/F pin combos. I have used this set quite a bit recently prototyping a project. Mostly making multi-conductor flat cables to connect sensor boards. The Dupont connectors are useful with breadboards and PCB pin headers. The JST connectors I have used less but are useful to connect components already having these types of connectors. There are plenty of pins and connectors of different sizes to cover any need. The pins lock in to the headers ok, but not as tight as a premade cable. Doesn't come with wire, so I bought a separate length of ribbon cable. The included crimper works great, making tight perfect crimps. The ratcheting allows partial closure to hold the pin while inserting the wire before doing the final crimp. Alignment is important so I put one dot on the wire side of the smaller crimp opening and two dots on the larger, easing quick orientation.

The Taiss Dupont Crimping Tool Kit is a huge time-saver for electronics and wiring projects. The ratcheting crimper gives perfect, consistent crimps every time, and it’s comfortable to use even for longer sessions. The included Dupont and JST connectors are neatly organized and fit great — no more loose or unreliable connections. It’s a complete kit that helps make DIY builds, Arduino setups, and repairs look professional. Highly recommend for anyone who works with small connectors!

Lousy instructions , Great Product. This works very well. What isn't clear is how to use it. It is actually a one step crimp unlike some other products. The V of the connector faces up in the tool when viewed from the side with the labeling. The back die is for the JST and the front is for the Dupont connectors. Made several custom plugs without issue.

Seems a pretty solid unit. Make sure you have magnification though. It all happens on the small scale.

Just what I needed, worth a little extra to get the full set with all the connector types and the crimpers. You could probably use pliers or other crimpers to make a so-so connection but the included set will make your work faster and more likely to be a sound connection. The anvils on the crimper have no "extra" on the width so you need to align the connector perfectly. Worst-case is that you'll need to re-crimp with the connector placed differently. This won't be a problem unless you're crimping every day for production runs. If you price the components separately this is a price for a set that covers your Raspberry Pi or other Dev boards perfectly. Having male/female and multiple size receivers of all of these is something I should've done LONG ago. The pics were my first crimps, probably one gauge size too big but it's what I'm using for this project.

Was sent the right Dupont connectors but the JST connector kit I was sent was 2.0mm pitch instead of 2.54mm, so I had to buy 2.54mm JSTs separately. Crimping tool is definitely not the highest quality but does work and is a good value.

Works as needed & best bang for my buck.

Good stuff. The crimping tool could come with instructions or at least the different teeth marked but for the price I'll let it slide. Everything works, no defects.

i have tried heaps of jst xh/ph 2.54 mm crimpers over the years , this one is the best i have ever encountered. its easy to use and makes a neat and tidy crimp with minimum fuss in one single movement it holds the connector nicely without deforming it allowing easy and accurate wire insertion.
