So why the two-star rating? That comes from the last part of the item headline - "with interchangeable die set." It's true, the die set included is held in the jaws with screws such that you can remove them and theoretically interchange them with others. Unfortunately, the tool does not include any other dies and the die mounting profile is not like any other "standard" ones that I've managed to find. Thinking maybe the manufacturer wanted to keep you buying their dies, I took a look at their website - and found nothing relevant except this very tool. So while it does include an "interchangeable die set," as far as I can tell you cannot interchange the included die for any other die set(s) available to purchase. Hmm.
I did the same inspection and a lot of research, and after a brief orientation period of trying different approaches I am now achieving excellent results with a very low failure rate (maybe 1 in 20). The are a couple of keys to success. First, the jaws have 2 different functions: crimping the tabs that go around the insulation and second, the tabs that go around the stripped part of the wire. Proper alignment is an absolute necessity to achieve the proper result. The connector must be inserted to the right depth (this varies with the male and female connectors), it must be flat and not twisted in the jaws. (Oh, and you have to use stranded wire, of course!) Some reviews have you align the connector on the left (looking down on the tool) but this is incorrect. The following works consistently for me:
1. Strip stranded (I used standard AWG22 stranded hookup wire) wire to 2.5mm for female, 3mm for male. This does not seem like much, but you only want enough length to cover the area under the wire-gripping tabs. Measure your connectors with calipers to ensure they are the same.
2. Close the crimper 1 click
3. Insert connector from the left with insulation-gripping tabs facing up
For the Dupont 2.54mm (0.1") connector (e.g Arduino boards) use the smaller opening (towards the end of the tool) even though it says
it is for 24-30 AWG wire.
4. Looking at the right side of the tool (from above) align end of wire-gripping tabs with the outside edge of the upper crimping jaw
5. Observing from the left, ensure the connector is perfectly flat along top of bottom jaw, centered, and not twisted in the channel
6. Insert wire at a slight angle, angling it slightly top to bottom inclined towards the crimper then aligning it parallel to the bottom jaw
(this is to clear the insulation tabs which stick up)
7. Observing the right side, ensure end of stripped portion of the wire aligns with the edge of the wire-gripping tabs, and then pull it back towards the left slightly so it is just inside the edge of the outer tab
8. Close the crimper the remaining 5 clicks and release
By following all these steps consistently, and doing so under a bright desk lamp so I could see everything in detail, I get nearly perfect results. It may seem like a lot of steps, but once you get the rhythm down, muscle memory takes over and this goes very quickly. You're also dealing with something very small, so accuracy and attention to detail matter a lot. The ultimate measure of success if the ease of which you can insert the connector into the header, and these will go in smoothly with minimal force and a satisfying click.
Now that I see the differences between the 2 tools, I understand now why the others are so terrible. This unit has curved faces on both jaws (in the Weirli, the top is flat) to help shape the insulation-gripping tabs rather than just flattening them. The jaw also has a slight rotating action as it closes, which seems to help the crimping process. The HT-225D also has much more surface area inside the channel (deeper walls) which helps to keep the connector aligned and not crushed. All of these small differences add up to much more than the sum of their parts.
Highly recommended. Hard to see how these realistically could be better. And still less expensive than other very similar crimpers I found online.
I forgot to post the review when I got them. So here's the review 4 years later. They still work as well as day #1. No problems whatsoever.
I tried to save some money originally and kept doing stripping and crimping by using crappy strippers and pliers. Garbage. I'd cut the wire or I'd mess up and pull the wire out. Got these and never looked back. I'd gladly buy two more if I needed them. But thankfully they're really well made and adjust to almost any reasonable gauge.
Highly recommended! Enjoy!
