12 Best RJ45 Crimpers Reviews in 2024

A crimper is a piece of very handy equipment used to deform the ends of wires and connectors to make cold weld joints between them. Among different types of connectors, the RJ45 connectors are the most popular connectors used in internet cables and other networking cables.

The RJ45 crimper makes it easy to crimp the cables and ensures strong reliable joints. Before purchasing an RJ45 crimper, you have to check if it is compatible with the cables you want to crimp.

Also, if you are professional, you need to get a versatile crimper. The crimper must not only crimp, but also cut and strip the wires. It eliminates the need for purchasing multiple tools and getting maximum value for your money.

Below are the different features you need to check before purchasing the best RJ45 crimper.

  • Supported Connectors: Apart from the RJ45 crimping, it is good to have a crimper that crimps other connectors. Especially, if you are buying a crimper for commercial purposes, getting a crimper that crimps RJ45, RJ11, and RJ12 can come in quite handy. RJ9, RJ10, and RJ22 are the other commonly used connectors.
  • Supported Cable Types: Similar to the connectors, you should also check the cable type that you want to crimp. There are different standards of CAT cables used in computer networking. The latest standard CAT 8 supports speeds of up to 40Gbit/s. Sometimes, different cables are used in the same linear connection. So, it is important to get a crimper that can crimp different CAT cables.
  • Positions: The modular connectors of the RJ45 crimper should be compatible with 4,6, and 8 positions, as these are the most common categories. If you are a professional worker, then you will need an RJ45 crimper that can work with more categories. 5 is another commonly used category.

Apart from these, there are several secondary features you need to check before purchasing the perfect RJ45 crimper. These features will give you maximum value for your money. You will find a complete list of such features in the “Buying Guide” section of this article. But before heading to that, please check out our curated list of the Best RJ45 Crimpers 2021.

Features to Check Before Purchasing the Best RJ45 Crimper

Welcome to the Buying Guide section of the article. Apart from the intended primary purpose, you should also consider the durability, comfort, and safety of the crimper. The following passage contains a complete list of features you should consider before purchasing the perfect RJ45 crimper.

1. Handheld vs. Hydraulic vs. Hammer

As the name has it, handheld crimpers are compact and are ideal for small wires. However, some high-end handheld crimpers also do a good job in crimping thick wires. The hydraulic crimpers apply more pressure and can easily strip thick wires. But they are expensive. Also, they are difficult to maintain and incur maintenance costs. You will have to replace the oil and filter periodically and ensure there is no dust inside.

The hammer crimpers are versatile options that can crimp a wide range of wires with the help of the moveable wedge. They are affordable too. The downside is it is time consuming and you have to exert more energy to crimp thick wires.

2. Durability

The RJ45 should be able to withstand tough work conditions and be able to cut thick cables for a long time. RJ45 crimpers made from cold-rolled are considered to be the most durable options. The whole body should have a sturdy build quality including the connector die and the handle. Having a crimper that can crimp thick cables easily will help you to achieve high precision.

3. Comfort and Ease of Use

RJ45 crimpers with a sturdy build quality often tend to be on the heavier side. Handling heavy crimpers is not an easy task and it will lead to less precision, especially if you are a beginner. So, it is important to strike a balance between the durability and the weight of the crimper. Also, most crimpers have a large head with a relatively small handle that can make it difficult to handle. So, go with a small and compact RJ45 crimper that is also lightweight.

Apart from this, some crimpers feature a ratchet that gives better control over the knobs’ tension. This can be a great option for beginners.

4. Safety

RJ45 crimpers are used for cutting, crimping, and stripping different types of wires and cables. So, it is very important that the RJ45 crimpers feature safety functions to protect you from injuries. For starters, the crimpers should have a blade guard to prevent accidental cuts. Plus, it should have a ratchet safety release. The handgrip should have a textured grip. This will not only provide comfort but will also ensure that you don’t lose your grip.

5. Warranty

No matter how durable and rugged the crimpers maybe, they are still susceptible to damage. So, it is important to get an RJ crimper backed by a warranty. The crimpers come with a warranty period ranging between 1-2 years. The warranty will not only protect your money but will also give you some peace of mind.
