Unlike the Preciva, this Knipex crimper is not heavy on the hands. You can use it all day on a project without feeling fatigued. Furthermore, the 20 degrees bend on the head increases its versatility. You can use it to crimp heat shrink, insulated nylon, non-insulated, ferrule, flag, and open barrel terminals. Key Features

Overall, I know the iWiss open barrel terminal crimper might not be the best in class but it works well for the money. It presses those weird small pins on Amphenol bulkhead fittings firmly and effectively. And you don’t pay through the nose for it! Wirefy Crimping Tool Set (8 PCS) – Most Versatile Crimping Pliers Set The entire kit comes in a case that makes it easy to transport and prevents the loss of terminals. In addition, the terminals are securely placed in a plastic box with compartments. For instance, I occasionally crimp open barrel terminals with regular pliers when I don’t have the right tool on hand. Open barrel connectors are pretty common in automotive wiring, especially on the pins of most automotive electrical connectors.Not only is the crimper exceptional at crimping heat shrink connectors but also crimps open barrel terminals very professionally. The open barrel crimping die set (#C) offers a crimping range of 20 to 10 AWG. The ratcheting mechanism of this tool enables you to securely hold a connector between the jaws so that you can easily insert the stripped wire.

But thankfully, the tool has 3 pivot points on the joint to increase leverage. This high-leverage design ensures optimal transfer of the squeezing force to the jaws. The crimper is factory-adjusted to apply sufficient clamping pressure to the jaws right of the box. However, if it tightens too much or not enough, you can adjust it using the adjusting screw on the left side of the tool.

0.5 – 2.5mm² Open Barrel Terminal Crimper

From the inexpensive crimping pliers for wire ferrules as a light and compact hand tool to the compact and universal Multi-Crimp® crimp system pliers and the semi-automatic, electrically driven eCrimp system pliers with over 1,500 interchangeable, different crimp inserts – with KNIPEX you have all the options at hand. It is also worth noting that this open barrel crimper does not have a ratcheting action. This means it will not hold the connector in the jaws without you squeezing the handles constantly. Due to the large number of different plug connections, crimping pliers in many different versions are required. As a rule, these pliers are operated with one hand - but there are also models for particularly large conductor cross-sections that facilitate two-hand operation thanks to their favorable design.

There is nothing significant to highlight, except that the instructions are not clear. Also, the weight of the tool can be quite overwhelming if you are using the tool continuously for a long time. But I guess that is the trade-off for the quality and sturdiness you get. Conclusion The crimping range is AWG 22-16, equivalent to 0.5-1.5mm². The tool is neither light nor too heavy. It weighs just like my other Preciva crimper for insulated terminals (above 1 lb though). So far, this tool has been working properly, and I haven’t encountered any problems so far. What I don’t like: The tool is made entirely of metal and feels good quality. The only plastic parts are the handle grips, which are made of hard plastic. But there is an ergonomic rubber overmold on them that provides a comfortable grip and prevents the tool from slipping during use. Moreover, you crimp insulated terminals differently from open barrel connectors. Best Crimping Pliers for Open Barrel Terminals Preciva SN-48B Crimping Tool – Best Overall

The Preciva SN-48B crimper set is my favorite tool for crimping open barrel terminals. After trying a few crimpers, I settled on this model for Faston terminals I was using for a car wiring project and this kit stands out. Key Features Overall, the Preciva SN-48B crimper performs its function effectively. It puts on those open barrel connectors onto wires neatly and professionally every time. I haven’t had any operational issues.

It comes with everything you need for your first task. The kit contains the crimper, along with 300 open barrel terminals of different diameters (2.8 mm, 4.8 mm, and 6.3 mm), which are suitable for cable diameters between 0.5 mm and 1.5 mm. I particularly like the ratcheting mechanism on these crimping pliers. It is nice and smooth and offers optimum force transmission to the jaws for fatigue-reduced operation. I usually use an automatic wire stripper to peel the wires, as it makes the work much easier for me. I strip off about 0.5″, insert a plastic sleeve, and crimp the connector in place before pulling the sleeve over the terminal. The Wirefy crimping tool set is probably the most versatile pliers kit. It comes with 6 different die sets to cater to the different crimping needs in any wiring project. Nonetheless, this tool is ideal for small connectors. No wonder the largest wire it can crimp is 14AWG (2.5mm2).Versatility is also demonstrated by models that, in addition to crimping, are also suitable for stripping and cutting cables. Lubrication* is recommended at least every 10,000 cycles whenever tool is exposed to dirt or other contaminants Just in case you are wondering, you cannot use terminal crimping pliers for insulated terminals to crimp non-insulated open barrel connectors. These two tools have different types of crimping jaws.
