The Best Crimper

Crimper Reviews

Our Top Pick is the Klein Tools VDV226-011

A crimper is a hand-held tool used to join two pieces of metal by bending them in a way that causes them to hold together. One example of crimping is when an electrician attaches a connector piece to the end of a cable. This is done by placing each wire into the connector, then the connector is placed into the crimping tool slot. Once the two wires are squeezed together with the crimping tool, the plastic connector is punctured while causing the wires connect. This, in turn, allows data to be transmitted through the connector.

Another feature that some crimpers have is not only crimping wires but also stripping wires. This process is done by inserting the desired wire into the crimper, clamping down on the wire and pulling the wire away which pulls off the wire casing. This exposes the wire that will be used to crimp with another wire via the connector. These stripping and crimping actions can be vital when hooking up or repairing electronic systems such as television, cable, installing fixtures, installing speaker systems, adding audio systems to your vehicle, upgrading electrical outlets and other vital functions we use day to day.

We conducted extensive research to find the best crimper available in the market. After thorough examination, the Klein Tools VDV226-011 ratcheting modular crimper rose above its competitors in both consistent performance and value. The steel construction with oxide finish will resist rust and enable the tool to last a long time. The comfortable grip makes it easy to use without causing hand fatigue. It covers the main wire sizes that are used in the electrical industry allowing you to use one tool for most applications. This crimper also has a mechanical ratcheting system for greater control.

Who Should Buy This

Crimpers are useful tools for anyone who works with wires. Given the low cost of the tool and its ability to efficiently connect wires, even occasional users will find a crimper tool useful to own. Anyone who is handy and wants to change out fixtures, install speakers or sound systems will find a crimper invaluable. If you want to install new technology in your home, need to conjoin or contour wires with connectors, or install car speakers, a crimper is what you need.  People who benefit from crimping tools are electricians, auto mechanics, audio installers, and those who work with professional or home theater systems. Home owners, computer techs, cable installers, and many others will find a crimper very useful.

What Makes a Good Crimper?

There are many components that make up a good crimper. The first of those being the crimp size. In many cases, crimping tools will come with several slot sizes to allow you to perform various crimping tasks. For example, common crimping positions are the ability to service sizes 4, 6, and 8 position modular connectors. The ability to cover a range of sizes such as RJ11, RJ12 and RJ45 are a few of the most common models out there. The wire gauges can go up to 50, with 50 being a very small wire. The higher the number, the smaller the wire, and the lower the number the larger the wire. This feature enables you to use the crimper for various wire sizes. You will therefore get more versatility out of a single crimper.

CrimperAnother useful feature in a crimper is a full-cycle ratchet mechanism. This prevents the release of the connector prior to full compression and will ensure that your wires do not slip out of place or not be fully crimped while they are in place. The ratchet system will often include a ratchet safety release option which ensures that your handles will remain locked in place and unable to spring open without you releasing the safety. This feature helps ensure your crimp is completed before you release the handle. Ratchet features become more valuable as the wire size gets larger.

Hand-held crimpers should include an ergonomic design in the handle and have a comfortable grip. These features will enable you to have a firm grip without creating hand stress during regular use.

Lastly, having a blade guard will reduce the chance of injury and offer a safe and secure way to strip wires should the task present itself.


How We Tested

We began our research by conducting a general search for crimpers that are available on the market. Crimpers are available in many qualities and those that only cost a few dollars were generally found to have very limited uses. From there we determined what features and qualities make up the best crimpers such as durability, modular size, safety release options, comfortable grip, and high levels of customer satisfaction. After reducing our list, we reviewed tool blogs, online forums, magazines, and received expert advice which allowed us to determine the best brands and models of currently available crimpers. We then consulted with prior customers and viewed dozens of customer reviews to find out which crimpers held up the best in real world performance.

Who Else Likes It

At one reviewer says, “As an all-in-one crimper/stripper, this does the job well. I was primarily focused on CAT5 cable termination, but having the flexibility to terminate other variations is worth the extra few dollars. The labeling on each side of the tool takes some getting used to, but once you get familiar with the various insertion points, it’s simple and does the job. The ratcheting system is solid, and certainly provides the force and guidance needed to get a clean termination. Solid product.”
