DeWalt FLEXTORQ 3/8" Square Drive Modular Right Angle Attachment Review

4.7 out of 5

Navigating tight spaces and awkward angles can be one of the most frustrating aspects of any mechanical or construction project. That’s where the DeWalt FLEXTORQ 3/8 in. Square Drive Modular Right Angle Drill Attachment, model DWAMRA38FT, comes into play. As someone who frequently finds themselves working in confined spaces, I decided to give this right angle drill attachment a try, and it has proven to be an invaluable addition to my toolkit.

From the moment I unpacked the FLEXTORQ attachment, it was clear that DeWalt had designed this tool with practicality and durability in mind. The attachment features a 3/8" square drive, which eliminates the need for additional socket adapters, making it incredibly convenient for quick changes. The head height is a mere 1.5 inches, which significantly improves accessibility in tight spots. This compact size is one of the key features that sets this tool apart, allowing it to fit into spaces where traditional tools simply can't reach.

One of the standout features of this attachment is its modular handle design. This compatibility with the FLEXTORQ Modular Right Angle System means that you can customize the tool to fit your specific needs. Whether you require a shorter configuration for tighter spaces or need to extend the reach, this tool offers the flexibility to adapt. The handle itself includes a small storage space, which, while a minor feature, adds a nice touch of convenience for storing small bits or screws.

The tool is also built to withstand tough applications, thanks to its forged gears and metal gearcase. This durability is particularly important when using the attachment with an impact driver, as the forces involved can be quite substantial. During my testing, the FLEXTORQ attachment handled the stress of impact driving without any noticeable wear or degradation, which speaks volumes about its build quality.

Using the FLEXTORQ attachment was a breeze. The attachment/detachment process is straightforward and quick – simply lift a lever and turn the head less than a quarter turn. This ease of use is crucial, especially when working in challenging environments where time and efficiency are of the essence. Additionally, the rubber overmolding on the sides and back of the body ensures a secure grip, even when my hands were greasy or oily.

One of the most impressive aspects of this tool is its performance in real-world scenarios. I recently used it while working under a car to access a bolt that was otherwise unreachable with a standard impact driver. The FLEXTORQ allowed me to complete the task in a fraction of the time it would have taken with a ratchet. Similarly, when repairing a lawn tractor, the attachment enabled me to remove bolts in tight locations without any issues, saving me considerable time and effort.

However, no tool is without its drawbacks. While the FLEXTORQ attachment excels in many areas, there are a few minor limitations. For instance, the body and handle collar cannot be used together, which might be a downside for those who prefer that functionality. Additionally, although the tool is robust enough for most applications, it may not be suitable for extremely high-torque tasks typically handled by impact wrenches. In such cases, a more specialized tool might be necessary.

Another point worth noting is that the handle, while generally sturdy, is made of plastic. This might raise concerns about its long-term durability under heavy use. During my testing, the handle performed adequately, but I can see how it might be a potential weak point over extended periods of demanding work.

Despite these minor issues, the FLEXTORQ attachment remains a highly versatile and practical tool. Its ability to work with both standard drills and impact drivers enhances its utility across various applications. Whether you're working on automotive repairs, construction projects, or general maintenance tasks, this tool is designed to make your job easier and more efficient.

In conclusion, I would highly recommend the DeWalt FLEXTORQ 3/8 in. Square Drive Modular Right Angle Drill Attachment for anyone who frequently deals with hard-to-reach bolts and screws. Its compact size, modular design, and robust construction make it an excellent addition to any tool collection. While it may not be suitable for the heaviest of tasks, its versatility and ease of use more than make up for any limitations. This tool has certainly earned a permanent spot in my toolbox, and I believe it will prove to be just as valuable for others facing similar challenges in their work.
