Review: A Dupont cable crimping tool that really works and looks like it will be my go to crimp tool. - I had almost given up with finding an affordable, easy to use crimping tool, for Dupont plug and socket crimp connectors that provided a crimp as good as the mass produced breadboard jumper wires. If you can get good mass produced jumper wires why bother with a crimping tool, It all about length with longer wires you get problems with the way an electrical circuit will operate. So I like to use commercial jumper wires and tailor them to the length I need for each part of the breadboard circuit. The "WISS SN-2549 Crimping Tools for Dupont terminal 0.08-1.0 mm² XH2.54/ 2.54/2.8/3.0/3.96/4.8/KF2510/JST Terminal Crimper Plier Ratcheting Wire Connector Crimping Tool " has proved to be the best quality crimping tool to date that I have found. A********* The ratchet allows the tool to hold the crimp pin or socket securely while inserting the wire. Once the tool is fully closed and springs open the crimp pin is easily released unlike other brands and the wire and sheath crimps are showing the same closure as the machine produced crimps, with a similar insulation resistance end to end as machine made crips. The crimp tool is a good fit for my hands and the crimping pressure required to complete the crimp is comfortable for making 20 or 30 crimps at a time. Really glad I bought this tool, desertcarts delivery time was also fast.
Review: Great crimping - An excellent crimp tool. Bought this to crimp the smaller JST Molex pins/connectors. These crimps have a narrower nose which is perfect for the small connectors. Crimps with a wider jaw will flatten the small tag that holds the connector in the housing. These work perfectly and produce a neat and tight crimp. Recommended..

## Features

- Crimping Range: 0.08-0.5/0.25/0.5/1.0mm².
- The components of the ratchet crimping are made of special steel.
- Wire Electrical Discharge Machining Cutting jaws with perfect polishing.

## Questions & Answers

**Q: Will this work with the jst rcy terminals**
A: Yes，it works well with this jst rcy terminals.

**Q: hi would this work with mcon 1.2 pin terminals**
A: From what I can find out, no it would not because they are solder terminals.

**Q: Are the teeth interchangeable? I don't want to buy two whole units, but I'd take one a several sets of teeth.**
A: There are two diferent size openings in a single set of jaws to suit the different crimp sizes. Have used extensively with PH 2.0 connectors. After a bit of practice to get use to handling such small parts, worked very well giving consistent crimps strongly attached to the wires. This is very high quality, well made robust tool. Have no idea if different jaw sizes are available.

**Q: Will this tool crimp molex 0.093 connectors**
A: I have used it without any issues on such molex connectors. So for me the answer is yes. Specifically I used it for the following that I bought for a project.
2 Way Molex Connector Kit .093" 2 Pin Plug Socket & Terminals. I use the IWISS SN-28B version of the crimper

### ⭐⭐⭐⭐⭐ Solid and well-made
*by S***W on 14 December 2022*

I'm new to using JST connectors so it took a bit of fiddling to figure out exactly where to sit the connector for crimping, but once this was done the crimpers seemed to do a reliable job. They seem to be precisely and robustly built for the price.
