In this edition about tools we will talk about the crimping tool. An instrument used to join two pieces of metal by deforming them so that they clamp together. Get all the information you need about this device with multiple advantages throughout the text.

You may wonder in which areas to use it. For example, having a crimper will allow you to attach a connector to the end of a cable. It is also indispensable when making telephone and network installations, as it functions as a crimping device and is essential for data to be transferred between the two.




Summary

  • A crimper is a plier-shaped tool used to attach connectors and terminals to electrical, telephone or network cables. It is a specific sales tool for a specific purpose, which is why there is such a wide variety of models, each with a specific function.
  • Are you looking for a crimper for domestic or industrial use? With this question in mind, be sure to determine whether you need a variable hollow-point or a plier with hydraulic features. Although all the proposals are related, they have very different applications.
  • Turn to the last section of the text. We bring you the four purchasing criteria that will help you to make a final decision. Presentation, accessories, design and cable thickness are the elements that we will consider in order to facilitate your final purchase process.

What is a crimping machine and what are its advantages?

We refer to an instrument that is used to join metals by means of a special connector. It has the function of a press to press firmly and in addition to that, it crimps, cuts and crimps the wires of telephone terminals or connection networks, in order to certify the passage of data through them.

You should always look for the secure connection of fine wires

Their applications are diverse. In metallurgy, for example, it is used to repair electrical connections. In everyday life, telephone companies make use of its benefits to establish functional communication systems. In the end, it is used for the secure joining of fine wires.

All crimpers have the shape of pliers, but are different from each other. Consequently, they have arms that are sometimes covered with plastic, so that your hands are not damaged during handling, and they are adapted to a particular application. In addition, they have a sturdy head made of aluminium or stainless steel.

Hollow or hydraulic toe crimper - what should you pay attention to?

Take a closer look at the most common alternatives on the market. From now on you will know two options. In any case, both will be useful if you work in areas where they are required. Do you want to know more? Prepare yourself for what is to come and make the final decision.

Hollow toe. This variable is designed for domestic use. You see, it is used to obtain a professional and safe finish when crimping the cables that you install in the electrical panel at home. It is achieved with an elongated, circular head, similar to that of a conventional pliers, each one with a specific purpose.

One of its most outstanding features is that it fits the connector without errors, pressing only the terminals. Therefore, it allows for a perfect finish, even if used by someone with little experience in the field. This punching machine is usually made of metal and plastic. However, there are expensive models that come in steel.

Hydraulic. It is distinguished from the previous presentation because it has a robust appearance and has a hydraulic cylinder that provides more force, even more than the user. The latter is necessary for crimping very thick wires and deforming brass, steel or copper connectors.

It is an indispensable tool in industry and hardware stores, as well as in the toolbox of professional electricians. It performs the action of joining two parts after they have been corrugated with hydraulic pressure. For example, it is used to crimp fibre optic cables used in a company's telecommunications.

Hollow point Hydraulic
Uses Domestic Industrial
Cables 1.5 - 6mm 10 - 25 mm
Strength Standard Superior
Material Plastic, metal Metal
Price Competitive High

Buying criteria: factors that allow you to buy and rate different models of crimpers

You have reached one of the most interesting sections of the text. We will share with you authentic content on the factors you should consider before making a final investment. Our approach is comparative: evaluate how each of these criteria influences the work you want to do with the crimping pliers.

  • Presentation
  • Accessories
  • Design
  • Cable thickness

Presentation

Hardware products come in various formats. When we talk about crimping pliers we can distinguish two at a glance. It is precisely in this first factor that we look at aspects of interest to you. Please pay close attention, as the type of presentation will have a decisive influence on your work.

Manual. Purchase a crimping pliers with these characteristics, if the thickness of the wires you are going to work with corresponds to a manageable diameter for your operating capacity. For example, take a model with a hollow tip if you are installing your network connection at home.

Electric. Designed for industrial work. Its purchase is an excellent recommendation for electronics professionals. However, we advise you to keep them in a special storage case to protect them from possible knocks. Due to its qualities it is important to establish a prudent budget.

Accessories

The crimping pliers are designed to perform their functions on their own. However, it must be accompanied by certain accessories to protect its integrity and enhance its exceptional performance. Do you want to know what they are? Here are the relevant accessories.

Carrying case. Choose to take home a pair of crimping pliers with a carrying case. You can buy the latter as a set or separately. It will help you to extend the lifetime of the equipment without knocking it, because although it is made of steel or aluminium, any dent will affect its function.

Terminals. They are part of the crimping tools. This suggestion applies especially to those who use a crimper professionally such as electricians, builders and contractors. Purchasing insulating terminals will allow them to start DIY projects and major electrical repairs without damage.

Design

Before making a final choice you should look at the design of your tool. Why? This has practical implications for the relationship you establish with your hand and the crimping pliers. Your work could be satisfying or uncomfortable depending on the type of tailoring you are looking for.

Ergonomic. Take home tools whose physical characteristics of the handle match the shape of your hand. Check the product description to see if it is rubberised or padded. This ensures that you get an anatomically shaped piece of equipment, which is ideal for massive connection work.

Industrial. We advise you to consider industrial designs, only if you will use them in conjunction with protective gloves. Why? They have a compact handle, made of stainless steel, which could cause damage to your hands as you apply force to cut the cables.

Cable thickness

It is common to have doubts about the thickness that crimpers can cut, especially if you are just getting familiar with this tool. That is why in this last criterion we will clarify what are the recommended diameters for the types of pliers covered in the product variables.

From 1.5 to 6 mm. For a domestic installation with flexible and sliding cables measuring between 1.5 and 6 mm in diameter, any hollow-point crimper is an excellent choice. Get one if you'll be working with lighting segments, utility sockets, air conditioning and heating, for example.

From 10 to 25 mm. Starting out in the electrical industry? Then opt for a hydraulic, ergonomic crimping pliers, capable of cutting segments in these sizes. It is specifically required for centralised infrastructures with very high current consumption.
