7 Best Automotive Wire Crimping Tool Reviews

Here is my list of the Best Automotive Wire Crimping Tools in 2022;

1. IWISS Open Barrel Terminal Crimping Tool

Best Automotive Wire Crimping Tool

See at Amazon!

As soon as it arrived, I crimped and wired the VW Audi coil adapter using 20AWG and 18AWG crimps.

CONGRATS! The brush section of several more expensive multiple die crimper sets could not be tightly crimped on a nice bellmouth with a good quality tight crip.

As a result, the crimper I recently discovered has become my new favorite.

My most commonly used crimp sizes are 18-22AWG with seals. When compared with crimpers that can cost over five times as much, this one performs extremely well.

The number of terminals I have assembled in my profession is no exaggeration. It is my personal experience that I am speaking of.

The crimping technique for weather pack terminals determines the straightness of the female and male terminals in assembled sockets.

With my needle nose pliers, I ended up with crooked ends even after trying to be as careful as possible. Connecting the sockets and plugs became tedious as a result.

Despite its low price, this tool is sturdy and provides the same results as expensive ones costing seventy dollars.

A MOLEX and other crimpers can sell for $500 & they aren’t more complicated than this tool.

This tool has a very affordable price and is comparable to more expensive products.

What We Like!
  • Handles are comfortably gripped by rubber
  • Easily cleaned up
  • Various wires and terminals can be crimped into four pockets
Things to Consider!
  • It is important to make sure that the jaws are aligned when using it.

2. Glarks 3PCS Automotive Crimping Tool

Best Automotive Wire Crimping Tools

See at Amazon!

According to my experiences with it, it’s quite well made for automotive wiring projects. The first time I crimped, snipped, and stripped the wires properly, it fits snugly.

This crimping tool kit includes a tool used to crimp wiring harness connections. This kit also comes with a multi-purpose hand tool and an electronic wire cutter.

The blue leather bag in which it is packaged is well-made. This means that it is portable and easy to store.

Due to the steel’s high-quality carbon content, it is particularly durable and strong for long-term use.

Ergonomically designed, it is easy to operate. Handles made from non-slip rubber are comfortable.

If dirty, the panels can be removed and cleaned. A single tool offers five crimp sizes. For a straight crimping engagement, the jaws are kept parallel by a double-hinge mechanism.

It applies to any semi-insulated or fully insulated but with a terminal connector.

In most automotive sealed harness connectors, the 22-10 AWG terminals on this tool work well.

What We Like!
  • Designed with ergonomics in mind
  • Rubber handles provide a non-slip grip
  • The crimps come in 5 different sizes
  • Semi-insulated electrical connectors are suitable for most types of fully insulated connectors, but terminals are not.
Things to Consider!
  • The handles make my hands itchy.

3. Wire Crimp Tool by Wirefy for Garage

Best Automotive Wire Crimping Tools 1

See at Amazon!

Well-packaged and as expected, the item arrived. Experience has shown me that many crimp tools fail to meet expectations; however, this tool is constructed well and is a fine example of how one should be used.

A ratchet mechanism ensures the correct pressure is applied, and the jaw pressure can be adjusted to handle a range of gauges and crimp quality.

The program works very well! My tool makes a perfect crimp every time, whether it’s crimping nylon crimp connectors or heat shrink connectors!
My only complaint is that the small release lever is difficult to use.

The crimper closes so tightly that there is not much room to push the release lever up with a finger. However, many other crimpers made like this use the same style, so maybe there is no choice.

According to my experience, right angle terminals do not work with the crimping tool because the crimp part is too short of grabbing with the crimping jaws.

In addition to this, there are many other options. It may have been the brand of terminal I tried to use, or it could have been that another jaw insert is needed, but I was unable to use it.

It is, however, an awesome crimping tool for all other straight terminals. Apparently, it would help if you crimped the entire way until it releases. You cannot release it if you crimp partially.

To crimp it all the way through, you will have to apply lots of force. Nonetheless, in my case, the connector is crushed in a way that resembles welding.

I want to make sure for those who do not know that the application has an auto-release feature.

The majority of people are unaware that the auto-release function of pliers only works when the pliers are completely compressed. Alternatively, some pliers can be closed to release the ratchet manually, but this becomes challenging when the pliers are closed.

The method I use to utilize the tool properly is as follows. First, place the wire at the correct distance from the light source.

There are specific length requirements for crimping 10/12/14/16 AWG wires. Second, to properly crimp a connector, you must line it up with the crimp tool properly. To crimp tightly, you might need to do so near the insulation and then further away.

As well as rotating the connector, it would help if you crushed the wire equally, so the break on the connector distributes the pressure.

The last step is to perform the pull test. You must make sure that both sides of the connector are crushed down if it pops off. In that case, you misaligned it.

What We Like!
  • The handles of the crimping tools are 6 inches long.
  • It has a feature of an auto-release mechanism.
  • It is possible to lock a connector.
  • Insulate against heat shrinkage.
Things to Consider!
  • MC4 connectors are not compatible with this tool.

4. Titan Ratcheting Wire Terminal Crimper

Best Automotive Wire Crimping Tools 2

See at Amazon!

My normal crimper has consistently let me down for years and years. There is nothing good about them. This thing is probably what you need if you’re here looking at it.

The old one ended up being thrown across the garage, narrowly missing the garbage can when I was irritated from bad crimps.

A small box without packing materials was included with the blister packs – no need to worry about that since it is merely a tool.

It’s much better this way. Because of the ratchet, you can hold the terminal in place while using this tool. Then, using one hand to insert the wire and the other hand to crimp, you can quickly crimp a wire.

I have used them for crimping insulated electrical blade connectors and barrel connectors from the small reds to the large yellows. The crimps are consistently solid. In electrical wiring projects around the house and automotive wiring, I have used them.

A beautiful one-handed operation coupled with a sturdy connection that I truly enjoy using.

In comparison to other crimpers, the price of this tool was reasonable, and the quality of the tool is solid, making me confident it will last several years. A smooth operation characterizes this mechanism.

The build quality seems high. It is so inconvenient to have to go to the workshop to retrieve this tool every time I need it at home to buy another one for my shop.

What We Like!
  • The construction is solid
  • Having a good grip
  • Crimps are solid
  • Suitable price range
Things to Consider!
  • Leverage was not designed well. There is too much space between the handles. The mechanical advantage is not enough.

5. Qibaok Crimping Tool for Automotive

Best Automotive Wire Crimping Tools 3

See at Amazon!

In the past, I would have loved to own these. However, crimps are consistent every time. Ratcheting is also a convenient feature. The tool is helpful for those who use heat-shrink wire connectors (such as those from Ticonn).

Furthermore, it can be used in automobiles and car stereos. Among their best features is the ability to stabilize and weatherproof connections.

To make this tool usable with one hand, the designers designed it to be used in a small space. Connectors without soldering are held in place by several jaws.

Despite the high quality of the product, it is reasonably priced. Neither this tool nor its handle will rust. Along with their superb finish, the crimpers are very thoroughly greased and very well assembled.

You get a flat crimp from these pieces since they do not have dimples.

It is no longer necessary to worry about wiring with these crimpers. This secures the wire and reduces the chances of slipping in the future, so there will no longer be any broken connectors.

In addition, Crimp pressure can be precisely adjusted with this feature. For a professional look, it is a great solution for your wiring project.

As opposed to the old connectors, the plastic no longer tears off the connectors. Adding this to the connector gives it a professional appearance. I have tried other methods, but that is by far the easiest.

I did not receive an instruction manual when I ordered. I will describe how to use it so it won’t be difficult. It’s important to insert wire terminals into the crimper in a specific way. On your terminal, there are colored dots where you can insert a wire.

It was set up well by the manufacturer, as far as adjusting it was concerned.

After the flat is crimped to the terminal, it will appear on the terminal at the location indicated. It is quite similar to the Klein 3005 cr tool, so you can also look up information about it on the web.

You already know how to use it from what I’ve explained above.

  • Several factors need to be considered:
  • AWG 10-20, total crimping range
  • While being crimped, terminals are never damaged
  • Heat shrink connectors of nearly all kinds can be connected to it.
What We Like!
  • Each of the jaw holes is colored to make it easier to identify them.
  • Easy adjustment of the ratchet mechanism makes it easy to use.
  • A handle with a soft grip feels better in hand.
Things to Consider!
  • Information on how to use the product is not included in its packaging.

6. Qibaok Ratcheting Wire Crimper for Automotive

Best Automotive Wire Crimping Tools 4

See at Amazon!

This kind of kit is nice. Because they’re easy to use and strong, crimpers alone are worth the price. By using the latching handle, crimping is made easier. Wires are crimped and then inserted into a mechanism after they have been crimped.

A wired setup suitable for this method allows it to be used to crimp with one hand.

The tool includes instructions that are easy to follow. The metal bits or wire gauges may be crimped with three different positions, making the crimping process flexible and flexible.

The process of crimping a 9-pin connector should not take you more than a minute once you know how to do it. In addition, you will need to spend far less time removing wires than stripping them (unless you have special wire-removal tools.

Additionally, I like how well the connectors fit together. Both plastic and metallic bits are well molded, so they are easy to insert and retain.

My main complaint about these kits (as usual) is that they include the right amount of male and female connectors to fill all connectors.

Because of this, if you lose even one pin, you will be forced to start from scratch. However, the connectors are pretty standard in size, and most folks won’t use them all.

My experience with it was great. To place the wire, the bullet needs to go in the crimper first. Once the wire is in the bullet, apply some pressure in an angular direction. Then, crimp down all the way. Crimping can be done at the same time on both wires and insulation sections.

What We Like!
  • Crimping requires less strength
  • User-friendly
  • This is the best choice for automobiles
  • Die swapping is possible
Things to Consider!
  • Crimping is possible up to AWG22-16 wire size.

By removing two screws, the crimping end can be removed to fit most types. Crimping is performed with high precision.

What We Like!
  • Crimping is made easy
  • Complex connections are made easier by it
Things to Consider!
  • The weight is a bit too great for the size.
