Crimping tool?

zapta · 2 Apr 2019, 07:12

I am getting very good results with this crimper https://www.amazon.com/s?k=B078WNZ9FW

It's handle is more comfortable and was able to get better crimps than with Engineer's PA-09/20/21.

@zapta I'll check it out!

@gnydick, I am using the 1.3 slot for crimping the conductor and 1.9 slot for crimping the insulation.

Before you insert the two wings into a slot to crimp, use the tip of the tool to press the wings to become parallel.

One advantage over the Engineer is that when you crimp the conductors, at one point the two wings collapse at once which makes a satisfying click that indicates that you are done. With the Engineer the crimping was more gradual, the more you press the tighter it crimps. (this is my experience, YMMV)

@zapta thank you!

The gradual crimping by the Engineer tool is what makes it so much more flexible, it can give you a good crimp for almost any wire size with some practice.

Hello,

I’ve ordered this crimping tools, the set come with 11 head, for my JST needed: http://s.aliexpress.com/3eu6rY3E

Is this kind of tool also works with Duet’s Molex kk or I’ve to get specific one?

Thanks,
Cookie

That crimping tool looks very versatile if you get the multi-jaw kit, however the jaws for JST or Molex crimp terminals are the SN-2 which it says cover 13 to 23AWG. It's not uncommon to use 26AWG, and some devices are supplied with 28AWG wires.

A popular ratchet crimping tool for Molex connectors is HT225D which is readily available in many countries. it will probably work on JST connectors too, but it doesn't do ferrules.

I have one of those, and while nice, I find it far too bulky to allow you to make decent crimps on smaller gauge wire you end up not being able to control the bulk and cant see what you are doing very well.

@dc42 Thanks. Yes, seem like at least thermistor wires are smaller. Also, like Calvinx said .. the head seem to be too thick to work with small wires. Then, this set are for other jobs .. mostly.

So, I’m going to order another one for small wires because this tool should last very long and worth buying, but HT-225D aren’t available in my region. There aren’t so many options with good reviews I could get. So, I’ve narrow down to these two:

1.) Iwiss SN-01BM $21.5 (my region) got a very good review from buyers.

2.) Iwiss 2820M $24 (my region), as suggested in comments above that could works.

Any idea Which one seem to provide better result or easier (I’m quite new to wiring) ?

Thanks, Cookie

I use SN-01BM all the time. The die seems very nicely made, should last forever.

I prefer the SN-01BM over the 2820M because it crimps both the conducting end and the insulation end in one go. I'm pretty good at using it, stripping the right amount and positioning the wire correctly, so it's not a problem not being able to see into it.

Because it does everything in one single action, you can't squeeze too tight and destroy the entire crimp. That's another advantage of the SN-01BM over 2820M.

the main problem I was having with my iwiss set is that the jaws are so wide, I couldn't wrangle the little parts together because I couldn't see what I was doing. That kit with all of the interchangeable jaws looks like it'd have the same issue.

This is also their down side, not providing consistent results as a good, and often expensive, ratchet crimper.

the jaws need to be that wide though, they are as wide as the crimps are

if you want to cheat, try this

strip the wire to the right length
put the wire into the crimp
using your fingernails, squeeze the insulating end of the crimp so that it is gripping the insulation
now when you insert the crimp into the crimper, the wire won't move around, making it easy

another tip is that some crimps come on reels, you might be inclined to clip it off of the reel first. DON'T! Cut the reel but keep that little tab attached to the crimp while you crimp, then cut off the tab.

and finally, do not: insert crimp into crimper, squeeze crimper half way, insert wire. Because that's how you end up not being able to see anything.

after buying several amazon crimpers and having poor results I found this crimper, works fantastic! thought I would share.

PA-09? Really?

This is my tool of choice:

https://www.amazon.com/gp/product/B00OMM4YUY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Well made, works great, crimps both wire and insulation at the same time, as the universe intended.

Well it is does not insure you complete the crimp, as does a tool with a ratchet.

It does not have replaceable/interchangeable "jaws".

It requires you to make two crimps rather than one.

And, at $39, it costs way too much for a tool as simple as it is.

The one I use and referenced is $23, which is nearly half the price of the PA-09 and has all of the features I mentioned that that PA-09 does not have.

To each their own but paying more for an inferior tool seems curious to me.

I'm sorry but that's just not the case, the PA09 if used correctly by someone who knows what they are doing produces perfect crimps...

Of course you can make good crimps with it. I could make good crimps with a pair of needle nose pliers if I had to. I've been in the industry for more years than I care to remember.

But why pay more for a tool that does less?

i have both the mdpc crimp tool and the pa-09.
I find that i use the pa-09 far more often.
