Dupont Crimping Tool Kit Ratcheting Wire Crimper with 2.54mm 600PCS Dupont Connectors and 560PCS JST XH Connectors,Female and Male Adapter Cable Connector Plug,JST Crimper(0.08-0.5mm² 28-20AWG)

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.

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!

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.

Had a hard time using the supplied tool to crimp the connectors onto individual wires. Not easy to get it to stay in place while crimping and sometimes the crimp doesn’t actually secure the wire. Maybe I need more practice but after about 20 wires across 3 or 4 connectors I just gave up and soldered the connection instead

I bought this primarily because the price was very close to just buying the crimping tool alone - so my expectations were lower. The tool is OK - not great but not bad. I have a similar crimping tool for larger sizes so this helps fill out my options. The packaging is somewhat comically labeled with buzzwords. I did dial the force down about 3 notches as the first test crimp broke the wire. After resetting the force, several perfect crimps. The kits are nice - worth the cost and a pretty good deal for the quantity. I subtracted 1 star for the lack of instructions with the tool (although the listing does a good job of describing how to use and adjust it).
