What is a Crimping Tool?

As hinted, a crimping tool is basically a piece of equipment which aids you in conjoining two pieces of metals.

It does so by deforming one or both metals in such a way as to cause them to hold tight on each other. The end result of this task is what is technically referred to as a crimp.

Purpose of Use a Crimping Tool

These tools play a vital role in attaching cables to connectors. For instance, the cables of networks and phones are generated using these tools.

They also facilitate the process of working metals and other tough surfaces. This is because they play a crucial role in deforming the substances to conform to the desired shapes, sizes, and postures.

How to Use Crimpers

Crimpers differ in their complexities and applications. Notwithstanding these differences, they exhibit some common characteristics and applicability. The following is the general procedure to follow to use a typical crimping tool:

Step I: Start by opening the handle of the tool. Follow this by inserting a contact into the crimping tool. Do this in accordance with the detailed diagrams that accompany the crimper.

Step II: Close the handle of the crimping tool. Do this making sure that the barrel and the terminals are not at all deformed in the process.

Step III: Insert the cable to the stopper of the conductor. Thereafter, close the handle until the ratchet releases.

Step IV: Remove the crimped contact, if need be, while reopening the handle.

Step V: Press the knob to open the handle during the crimping exercise.

Benefits of Using a Crimping Tool

These tools serve a variety of tasks and purposes in the field of metalwork and construction. Below are but a few of those uses to which they may be put:

Cut Wires

This tool can cut wires. This is especially the case for RJ-45 connectors. It can also play the same role for the RJ-11 connectors. This stems mainly from the fact that it comprises the wire cutter and a built-in cable stripper. Being portable, they can also cut wires while on the go.

Handle Cables

With this tool, you may support, place, or hold cables correctly in place during a crimping process. This is mainly because it has a pushing bar and an adjusting nut. These are the components that fasten the said materials appropriately during the crimping process.

Terminate Components

Apart from handling cables and cutting wires, you may also terminate some kinds of wires. These include the twisted pair modular plugs, compression connectors, and the jacks. These help the said wires to fix effectively in the item they are connected to.

Join Specific Connectors

You may also use this tool to join specific connectors. This is because the tool has connector shut heights which are specifically engineered for the various specific connector requirements. This way, they enhance the strength and the reliability of the joints.

Strip Wires

Lastly, you may also strip wires using this crimping tool. This simply means peeling off the rubber coating that insulates the wires to prevent direct contacts with the same. This tool can handle all kinds of wires like nylon, rubber, neoprene, PVC, Teflon, standard, and the solid wires, among others.

What are the Components of a Crimping Tool?

The following are the major parts and components of the crimping tool:


This is the portion of the tool that does the actual task of crimping. It occupies the portion of the tool that is directly opposite the handles. It is round in shape and is designed to capture the load and hold it tight.


The ratchet engages the teeth and the handles of the crimping tool. It is what sets the strength and the tightness of the device to respond to the unique weight and nature of the load.


It is the handle that you get hold of to carry and engage the crimping tool as need be. The handles of the crimping tool are shaped in the form of those of the pliers.

Open Knob

Coming in the form of a rounded ball that is found at the handles of the tool. The knob regulates the opening and closing of the crimp and the mouth portion of the tool.


Located inside the crimper, the contact is what holds the load tightly. This way, it makes it easier for the load to be worked on appropriately.

Conductor stopper

Conductor stopper is basically a plug that seals the load tightly. This is to make it safe, secure and reliable at all times by preventing it from swaying back and forth while in the process of being worked on.

TIPS TRICKS and Maintenance Guide

Ascertain the Compatibility of the Devices

Be sure to ascertain the compatibility of the device and the load you intend to handle. Specifically, ensure that the crimping tool measures up to the wire or the terminal you intend to crimp. This is to prevent any mishaps of inconsistencies during the crimping process.

Check the Validity of the Heights

After crimping the items concerned, check that the heights of the crimps are valid. This again is to see to it that the outcome you have received is legitimate.

Keep the Tool Intact at all Times

Make every effort to keep the crimping tool intact at all times. Do not attempt to remove the screws from the tools. You should also see to it that you do not disassemble the tool at all. This is to prevent any failures and the associated injuries that accompany these problems.

Use the Tool Moderately

Do not overuse the tool. Only use it if and when you absolutely have to. Overuse will often accelerate the pace of deterioration and increase the rate of wear and tear.

Seek Expert Advice Always

In case you are stuck seek expert advice. The expert here should ideally be a person who is knowledgeable in matters engineering.

Care and Safety

Regular Lubrication

Make sure you lubricate the movable parts and components at all times.  Lubrication reduces friction and also slows down corrosion and the subsequent deterioration of the said parts. You should do so moments before use and before a long storage process. Please do not lubricate the crimp as this might interfere with the operations of the tool.

Thorough Inspection

From time to time, inspect the tool thoroughly. In particular, get rid of the extra materials from the stripping as well as the scrap metal from the stopper of the cable. Doing this sees to it that the item works optimally at all times and ward off any operational problems.


Always store this tool in a cool and dry place. When exposed to moisture, the tool corrodes and deteriorates in quality. This not only interferes with the functioning of the tool but also predisposes you to all kinds of injuries.


While in store, ensure that the tool is as far away from the reach of children as possible. This tool is very dangerous and has the potential to inflict injuries. You do not want to subject your children to these injuries, do you?

Replacement of Faulty Parts

Every quite often, be sure to check for any faults in the constituent parts and components of the crimping tool. In case you notice any dangers or weakened joints, do not hesitate to replace them soonest possible. This will prevent further damages and the attendant injuries that do come along with the situation.

What to Look for When Choosing a Crimping Tool?

In your search for the right crimping tool be sure to consider these, and indeed so many more other pertinent factors:

Volume of Operations

How many tasks do you intend to handle at any given time? Do you intend only to use the tool for small light tasks or for many heavy tasks? In case you intend to use it for the latter, you require a tool that is too huge and is very high in quality. A small and lighter tool will, however, do for the former.

The Complexity of the Tasks

How complex are the tasks at hand? Extremely complex tasks require more sophisticated tools. These tools subsequently require some great deal of technical expertise and skill from you. The lighter tasks, on the other hand, require only the most basic of the crimping tools available.

Warranty and Certification Requirements

Different tasks and items require different standards. To prevent a clash between the expected final outcomes and the set standards, be sure to settle for a tool that is accredited for the said purpose. Do some research first and foremost before proceeding to look for the most appropriate tool.
