DeWalt 12-Ton Died Cable Crimping Tool Kit Review
DeWalt has long been a trusted name in the world of power tools, and their crimping tool, the DCE300M2, promises to uphold that reputation with a range of impressive features and robust build quality. After putting this tool through its paces, I have gathered enough insights to provide a detailed review that should help potential buyers make an informed decision.
Starting with its crimping capacity, the DeWalt DCE300M2 can handle both copper and aluminum cables up to 750 MCM. This is a significant capability, making it suitable for a variety of heavy-duty applications. The tool is also equipped with integrated software that provides detailed reports on crimping operations, a feature that adds a layer of professionalism and precision to the work. The onboard diagnostics show battery status, completed cycles, and service requirements, which is incredibly useful for maintenance and ensuring the tool is always in optimal working condition.
One of the standout features is the LED light, which is a godsend when working in low-light conditions. This feature, combined with the 270° pivoting head, makes the tool very adaptable to tight spaces and awkward angles. The forward and reverse switch enables one-handed operation, which is a thoughtful touch that enhances ease of use. Additionally, the inclusion of a shoulder strap for easier transport is a practical addition, especially considering the tool's weight and size.
However, the performance of the tool leaves something to be desired. While the crimping speed is adequate, there is a noticeable lag between crimps that can be quite frustrating. This lag often requires multiple trigger presses before the tool re-arms and is ready for the next crimp. This issue can slow down workflow significantly, especially in a professional setting where time is money.
Durability is another area where the DCE300M2 could improve. There is a metallic rail/guide under the moving part of the press that tends to break after a few uses. While the tool still functions without it, this is a disappointing flaw in an otherwise robust build. Moreover, the set screws that keep the dies in place can become stuck after crimping, necessitating repairs or replacements. This issue can be a significant inconvenience, especially if you are in the middle of a critical job.
The weight of the tool is another aspect worth mentioning. While it is robust, it is also heavier than other crimpers with the same ton rating. This can make extended use tiring, despite the shoulder strap. If you are planning to use this tool for prolonged periods, be prepared for some arm fatigue.
One of the most significant drawbacks is the availability of compatible crimp dies. The DCE300M2 is compatible with U-Type dies from various manufacturers, but sourcing these dies can be a challenge. Many places are often out of stock, and DeWalt does not include a die set with the tool, which would have been a thoughtful addition. This issue can delay projects and add an element of frustration to the overall experience.
On a positive note, the tool's battery life is commendable. Since it runs on the same platform as other DeWalt power tools, you can easily swap batteries, ensuring you never run out of juice mid-project. The tool also comes with onboard diagnostics that help you keep track of battery status, completed cycles, and service requirements, adding a layer of convenience and efficiency to your workflow.
Despite its flaws, the DCE300M2 has some redeeming qualities. It is a sturdy, robust tool that performs well when it is working correctly. The integrated software and onboard diagnostics are valuable features that set it apart from some of its competitors. The LED light and pivoting head make it versatile and adaptable to various working conditions, and the forward and reverse switch for one-handed operation is a thoughtful addition.
However, the tool's performance issues, durability concerns, weight, and the difficulty in sourcing compatible dies are significant drawbacks. These issues can hinder productivity and cause frustration, making it hard to justify the tool's high price tag.
In conclusion, I would recommend the DeWalt DCE300M2 with some reservations. If you are a professional who can deal with its quirks and have the patience to source compatible dies, it can be a valuable addition to your toolkit. Its robust build, integrated software, and onboard diagnostics offer a level of sophistication that is hard to find in other crimpers. However, if you are looking for a tool that delivers consistent performance without the hassle of frequent repairs and hard-to-find accessories, you might want to consider other options.
Overall, the DCE300M2 is a solid tool with some notable flaws. Whether it is the right tool for you will depend on your specific needs and tolerance for its shortcomings.
