RJ45 crimpers: types

Not all RJ45 crimpers are usable with round and flat Ethernet cables. However, the best crimpers are capable of cutting Ethernet cables of both types.

We can categorize crimpers in 3 ways-

  • Handheld– Although the premium quality handheld crimpers can deal with thick wires, we mostly use them with small wires. Moreover, some feature-rich models are also effective for cutting and stripping process.
  • Hydraulic– Hydraulic crimpers enable you to apply much pressure. You may use them to work on thick wires. However, these hydraulic models are costly and need regular maintenance. You have to replace the oil to prevent clogs.
  • Hammer– The affordable and compact hamper crimpers can crimp a range of wires. It is easy to crimp wires of different sizes after the adjustment of the movable wedge’s height. One of the cons is that you must make a number of strikes while dealing with thick wires.

Check out the connections

The best RJ45 crimper must be compatible with three connections- 8, 4, and 6 positions. In the past, we used to choose RJ45 cable only for telephone connections. However, technology developments have led to the 5 and 6 connections. 

Is your crimper versatile? 

You have to focus on the versatility of your RJ45 crimper. Some brands have designed crimpers for multi-functional uses. We think that it is better to use top-quality crimpers to get the ultimate value from your investment. 

The innovatively designed crimpers are capable of managing the crimping tasks of different sizes. Moreover, it will be easy for you to accomplish the crimping process without using another crimping kit. To deal with your telephone cables and other types of wires, you can pick the best quality crimping tool.

Know about the durability of the product

As you think of investing in a crimper for professional and personal needs, it has to be durable. You need to use the crimper regularly, and thus, the tool must have a durable construction. A highly resilient crimper has the power to make your crimping process successful. Without an actively designed crimper, you may find inconsistency in performance. 

Thus, the product quality is one of the most important factors to purchase the right crimper. Nowadays, manufacturers have used cold-rolled steel to design this crimper. You can crimp thick cables with this tool. Moreover, the connector die must be highly sturdy, and you have to check out the balance of weight and thickness of your crimper.

Ease of gripping the tool

You may need to hold the RJ45 crimper with your hands for long hours. That is why your crimping tool must have an ergonomic grip. Plastic grips may not be comfortable for you, and they can be slippery. Conversely, rubbery ones are the better choice for you. You will not feel discomfort while gripping the crimper.

Additional features with the kit

A quality crimping tool must have network cables and connectors. When you deal with only RJ45 connectors, it is better to prefer a specially designed RJ45 crimper. However, with some additional functionalities, you will have a higher value.

For instance, some tools work as crimpers, cutters, and strippers. The system must include a ratchet design for automatic closing of cutter and crimping section.

Compression versus Indent

The indent style crimp is the right choice to crimp compacted and fine stranded conductors. A small handheld crimper is useful for indent crimping. Conversely, compression crimping needs consistent force to prevent conductor damage. To work on copper and aluminum cables, you can choose compression cables.


We have tried to provide you with the most useful information on RJ45 crimpers. Read our reviews thoroughly and find the best RJ45 crimper for your needs. Although crimpers are small tools, each of their features is important to do proper crimping.
