Crimping Tools Buying Guide Plus How to Use It.

As an electrician, DIY, or network engineer, you need a crimping tool in your toolbox. It is a compression tool used in electrical connection and cable crimping.

A crimp tool helps you join two network cables, or a wire and a connector. When a wire is joined to a connector such as a lug, it is called a crimp.

Crimpers come in varying sizes in line with the American Wire Gauge (AWG). Some have replaceable die heads to contain a wider range of wire sizes and connectors.

At, we use crimp connectors daily and also know their qualities. This keeps us on the edge of suggesting the best quality crimpers for you.

Below are the top 3 crimpers we recommend for you.

We will also show you how to use and adjust the hand tool.

Functions of crimping pliers

It does the same work with electronic solders; they weld or join two wires together. But unlike the soldering iron that joins network cables with alloys, crimp tools use mechanical force to create a stronger and rust-free crimp.

How to use the hand tool

Using a crimper is quite easy, all you need is to strip the length of wire you want to crimp with wire stripper and fix the connector.

For crimpers with interchangeable die sets, choose the right head for the connector by matching the wire gauge rating. Finally, crimp the terminal and make sure it is strong for data transmission.

Types of wire crimpers

There are three types, they include:

  • Handheld crimpers
  • Hydraulic 
  • Hammer crimping tools.

Handheld crimp tool

This is the simplest and most common crimper you can get on the market. They are manually operated and are used to crimp small wires and even jewelry.

Some are multi-purpose and can do the work of wire strippers and pliers.

Hydraulic crimper

This crimper uses more pressure than the handheld and can also crimp thicker wires. But unlike the handheld, they need regular care, such as changing oil and filters.


This tool comes with a movable wedge which allows the crimping of various sizes of wires (small and large wires).

The downside is that it’s not that portable, and must also be placed on a flat surface before use.

How to choose the best crimp plier

When going for a new tool, there are certain things to consider.

  • Easy to use: An easy-to-use crimper can make wire crimping faster and neater.
  • Wire gauge: The gauge of the wire and that of the crimper must be the same.
  • Features of the crimper: Some are multi-purpose, others have set die heads. Your choice must tally with the work you intend doing with the crimper.
  • Price of the tool.

Care and maintenance of crimp pliers

Like other electrical tools, crimpers need regular care and maintenance to last longer. Although their lifespan will depend on the working environment and frequency of use, regular inspection of the tool will also help.

Below are the ways to care for the hand tool

  • Regular inspection to make sure the screw, spring and moving parts are in order.
  • Frequent lubrication of joints, bearings, and pivot points.
  • Only use the tool for crimping work
  • Don’t clean it with hash material
  • Keep it away from dust and moisture.
