 The most acclaimed crimping tool of 2022! Help ensure safe electrical connections with the best crimping tools

September 05, 2022

Whether you are an experienced DIYer or a skilled contractor, you may need to patch wires regularly to help establish safe electrical connections. Some people try to repair wires and terminals themselves, as hiring a qualified electrician can be expensive and this can seem wasteful, especially if the task at hand doesn't require a lot of expertise. If you have a heavy-duty crimping tool, you may even be able to carry out some of the smaller repairs yourself.

Crimping tools use terminals to create a tight seal on the wires, helping to protect them from water and dirt. But with so many crimpers to choose from, it can be difficult to select the ideal crimper for your specific needs and setup. With this in mind, we've compiled a list of some of the top crimping tools in 2022 to help make your DIY job easier.


Finding your next crimping tool: a buyer's guide


If you're a handyman or DIYer, your kit should probably include some quality power tools that can help you make quick fixes around the house. A crimping tool can be one of these tools when the wires don't have the right connectors. This buying guide should help you get almost all the information you need to buy the right crimping tool for your particular job and setup. So let's find a new tool for you!


How to choose a crimping tool


Compatible wire gauges

One of the first things you should check is whether the wire gauge fits your crimping tool. This should help you to get a better idea of the type of wire the tool can crimp in terms of thickness and diameter.

Wires are usually rated for thickness using American Wire Gauge (AWG) and most models range from 12 to 24 AWG, so you should choose a versatile tool that you can rely on to crimp almost any size wire.


Crimping chamber

If you are a professional contractor who often needs to crimp wires of different diameters, you should buy a crimping tool with at least three crimping chambers. In other words, a crimper with more chambers should allow you to crimp different thicknesses of wire without having to switch between crimping pliers, which will help you save time and also reduce the weight of your kit. 


Punching or etching marks

Some crimping tools have metric and imperial sizes etched into the jaws. This helps to keep everything in sight as you work, helping you to save time and increase overall productivity.


Ergonomic handles

It is vital to find crimping tools with a comfortable grip. Not having a padded handle can lead to hand discomfort and fatigue - and no one wants that. That's why you should look for crimping tools with ergonomic handles and cushioned grips.



Make sure you are using the right crimping machine for insulated or non-insulated connectors. Crimping tools for insulated terminals have round jaws to protect the terminal insulation. Using a non-insulated crimper on insulated terminals may damage the insulating sleeve or result in under or over crimping.


Open or closed barrels

There are two types of terminals: open barrel and closed barrel. The most common type used in the terminal industry is the closed barrel. They are available in insulated and non-insulated versions, are easy to group and come in a variety of forms and sizes. For closed terminals, oval or hexagonal crimps are usually used.

Open barrel designs, on the other hand, offer the highest resistance to vibration and corrosion and are often used for automotive wire harnesses and high volume applications. The "F" crimp is also the most common crimp design for open barrels.


Manufacturer's specifications

Most terminal manufacturers will specify the type of crimper you should use, so be sure to check the manufacturer's specifications. If you need to comply with Underwriters Laboratories (UL) standards or other standards, it is also important to follow the manufacturer's crimping tool requirements. 


How does the crimping tool work?


Removing the wire casing

The first step is to remove the rubber casing of the wire, but if you cut it completely open, you may damage the copper inside. Instead, simply cut an even circle around the wire and remove the casing. With the copper exposed, you will be ready for the next step.


Inserting the connection

There are various connections available, such as open barrel connectors. You can also arrange the wires within this connection before easily crimping them. Then, use the ratchet mechanism on the crimping tool to help you position the connection in the jaws. Then, use the star wheel to adjust the force so that the crimp is as tight as possible. Also, the tighter you crimp the wires, the less likely they are to break over time.


Crimping the wires

The wires are then inserted into the connection and you simply squeeze the handle to crimp them together. This may require a little power from some crimping equipment, but it is the best way to get the job done. If you think the position is incorrect, click the quick release button to open the jaws before the crimp is complete.

When you have completed this step, you should have a nice crimp wire in front of you.


Why use a crimping tool?


Crimping wires helps to protect them from dust and grit, thus extending the life of the cable, and it is also a cleaner and easier technique than soldering. Plus, when you use a crimping tool, you don't need anyone's help to get a great crimped wire at home.

Crimping can also be more reliable as it presses the connection firmly into the wire, creating an airtight seal. Most crimping tools are very expensive, but we offer several inexpensive and high quality options above, so these products are definitely out there.


Types of crimping tools



Hand-held crimping tools are similar to standard pliers, but they also have a die in the internal jaws for crimping the wire into the connector. These dies can come in a variety of shapes and sizes depending on the size and type of connector being used.



For larger and heavier gauge wires, bench top wire crimpers are ideal. They have a much stronger mechanism than portable crimping tools and can apply more force to the wire and connection. These crimping tools also have larger and heavier dies.



These crimping tools use hydraulic pressure to compress the connection onto the wire, making them ideal for very large, thick gauge wires and connectors. These crimpers are typically used in industrial applications and are operated using hydraulic fluid.



With this type of hand crimper, a hammer is used to squeeze the connection onto the wire. It is not as common as the other types, but it has some applications. Although these crimping tools can handle thicker wires than other versions, they are not portable enough to transport to the job site.
