Micro Molex Crimper: Compatible with D-Sub, JST, JAE Connectors, 32-20AWG / 0.03-0.52mm², Ideal for Wire Crimping, Electrical Repairs

I’ve done many many crimps with the $600 molex microfit 3.0 crimpers. That said, I was highly skeptical of these weird name knockoffs, but for $25 I figured it was worth a shot. First impression is that they feel like surprisingly good quality. The action is smooth, doesn’t feel loose makes a good crimp. It does not have a pin clip/gaurd which is fine you can just hold it by hand till the first click. However, you do have to be mindful of the wire placement as there is no gaurd to stop you from putting it in too far. Can’t say much for durability since I just got them. But honestly if these hold up even decently well, they should rebrand to something that doesn’t sound like a knock off and raise the price. So far so good.

I could have purchased this tool for a significantly higher price at another source. Took a chance and bought this one, works great.

I purchased this crimper for some different connectors, but found out they are ideal for some JST connectors I had

worked great good value

This tool does an excellent job crimping the JST-XT type terminals as listed in their description. But, this isn't the tool to use to crimp model airplane servo type connectors. The crimpers jaws are not wide enough. SO, for the JST-XH type connectors, it's an easy 5 stars. For servo type connectors, for me, there are much better crimpers for these cables. (My crimper tools in my workshop includes around a dozen crimpers for these cables. Some very good, some $6.00 crimpers are garbage)

Pros: does what its supposed to. Cons: the pivot bearing is slightly leaking oil on mine making it a bit unexpectedly messy and within a few crimps the lower handle is starting to pull off when using. Easily slides back into place, but its an extra step in usage. Both of these are very minor and the tool functions exactly as needed. However this is the difference in a quality tool and a cheaper alternative.

When using a crimping tool of this type, you must insert the crimp pin up to the part that wraps the insulation. Those 2 wings prevent the crimp pin from falling inside the crimper. Then, close the crimper lightly to hold it in place, insert your stripped wire into the crimp pin, crimp it down, and then open the crimper again and crimp around the insulation. Otherwise, it's just impossible to get the terminal crimped on correctly. You might also need to experiment with the size of the crimp channel for any given connector. The correct one is usually larger than you would guess. This crimper is one of the better ones.

Bought for small pin crimping, worked as described. No need for me to buy a real pricy set.

Very precisely crimps the ends looks like professional did the job but was just me

Decent enough quality product for the price. Great build Quality.

Connecting up plugs for model train set.

One of the best quality crimper you can get for micro connectors

The tool works OK, spring on the Rachel is a little weak however the tool does work well.
