Engineers Precision Crimping Pliers PA-09

I had few picoblades in my design. This crimp tool can handle picoblade connectors. It forms nice crimp. I was able to get reliable crimps in first attempt itself. This is not a sophisticated crimp tool like molex. however, with 1/5 the cost, I can achieve the crimp.

It’s a genuine Japan made product, perfect and easy to use

Love this thing, anyone who doesnt has a skill issue.

Best tool I ever had for JST crimping, including ZH size, which is tiny. Recommended.

I’ve become a big fan of ENGINEER tools over the past year, and they’ve quickly become my go-to brand for precision electronics work. The quality and attention to detail have been consistently excellent, and these PA-09 crimpers are no exception. I already own a ratcheting crimper, and while it’s great for larger terminals, I’ve found it to be a little too bulky and aggressive for delicate JST and other micro connector pins. The PA-09 gives you much better control over the crimping process, allowing you to feel exactly what’s happening instead of relying on a ratchet mechanism. That extra precision makes a noticeable difference when working with tiny open-barrel terminals. The dies are well-machined, alignment is excellent, and the finished crimps come out clean and secure with very little effort once you get the hang of the two-step crimping process. It’s a versatile tool that handles a wide range of small connector types, so I don’t need a dedicated crimper for every style of terminal. The build quality is exactly what I’d expect from a tool made in Japan—solid, smooth, and built to last. If you spend much time assembling cables for electronics, 3D printers, RC projects, or microcontroller boards using JST, Molex, Dupont, or similar connectors, this is a worthwhile investment. It isn’t the cheapest crimper available, but the improved control and consistently better crimps make it well worth the price.

Wow do these work well. I struggled for some time with another brand of ratching crimpers that were cheaper and thought would suit my intermittent use needs. I had all but given up on making JST crimps since most of the time they mangled the connector or the crimping was not tight. For my first few crimps with these, I tried the 1.9 mm die for some smaller JST connectors. Once I switched to a smaller die every crimp was perfect. Goes to show what a quality tool can do.

Excellent product. Tried a cheaper random brand ratcheting crimper and all it did was make a mess. These units have a precision jaw profile and the JST crimps actually work. Narrower profile allows a better view of what you are crimping and taking two crimps to complete the termination is not an issue.
