How to Pick the Best Wire Crimper Tool: Step by Step

When choosing a wire crimper tool, there are three main considerations for most buyers.

  • Performance
  • Durability
  • Comfort

Let’s review each of these criteria in more detail.

Performance

A high-performing crimper ensures durable connections that won’t come apart under pressure. We recommend looking for a crimper tool with a ratcheting mechanism. This will guarantee precise force application, preventing both under-crimping and over-crimping.

Without a ratcheting mechanism, you may find yourself guessing how hard to squeeze, leading to inconsistent crimps or repeatedly performing the same crimp due to uncertainty. Opting for ratcheting crimpers will ensure that your terminals are secure, as they apply the correct amount of pressure to get the job done.

Durability

If you’re investing in wire crimper tools, chances are you’re planning on crimping more than one terminal. Consequently, they’ll need to withstand the pressures of frequent use and continue to deliver consistent crimps over time.

To avoid replacing your crimper down the line, we recommend choosing one that is durable and well-built. Look for a crimper from a reputable brand that is made from high-quality materials such as hardened steel jaws and hot-riveted joints.

Comfort

Since the vast majority of wire crimper tools are designed to be handheld, you’ll want to prioritize comfort so that your strength or endurance doesn’t limit your job. Crimpers with long handles can provide additional leverage, making it easier to exert the necessary force.

Furthermore, well-designed handles should allow for a secure grip. They should feel like a natural extension of your hand, ensuring maximum control.

What to Know Before Buying a Wire Crimper Tool

Wire Gage

Different electrical projects involve wires of different sizes, commonly represented using the American Wire Gauge (AWG) system. In order to ensure compatibility, you must choose a wire crimper that is custom-built for your chosen wire gauge. If your projects involve a wide range of wire sizes, you have two options: invest in multiple specialized tools or choose a versatile crimper that can handle various wire gauges.

Each option has its advantages and disadvantages. A versatile tool streamlines your workflow by eliminating the need for tool switching, but it may require wider handle openings to find the correct groove. This could be potentially uncomfortable and may lead to hand fatigue over time.

In contrast, specialized tools provide precise crimps tailored to specific wire sizes, but you might need to switch between them, causing interruptions.

Ultimately, the choice depends on the complexity of your projects as well as your preference for convenience versus specialized performance.

Terminal Material

The material of the terminals you work with can vary, such as insulated, non-insulated, or heat shrink connectors. Among those options, the hardness and thickness can also vary.

In order to get the best results, you must carefully consider the compatibility of your crimper with your materials. Even the best crimper applied incorrectly can cause damage and compromise connections.

To avoid such issues, choose a crimper that is designed to handle the materials you work with. Some crimpers offer the advantage of fine-tuning the crimping pressure, allowing you to adjust based on your materials.

Crimp Profile

Crimp profiles refer to the shapes and configurations of a crimped connection, such as hexagonal, square, circular, and indent. While many crimpers can handle various wire gauges and materials, it’s less common for them to support multiple crimping profiles.

Using an incompatible crimper can result in weak joints, intermittent connectivity, or even complete failure. Therefore, it’s crucial to select one that matches the required crimping profile for your specific terminals.

Using a Wire Crimper Tool: What It’s Like

When you pick up the right crimper tool, its reassuring grip will instill a sense of readiness to tackle your job. Intuitively positioning the terminal within the jaws, you’ll find it effortless to clamp down, thanks to the tool’s ergonomic design and leverage. Even after numerous crimps, your hand won’t fatigue and the crimper will continue to create consistent connections.

In the end, it will be a rewarding process knowing that your electrical connections are strong, safe, and built to last.
