DeWalt Modular Right Angle System Review

4.4 out of 5

Navigating tight spaces and awkward angles during a project can be quite a challenge, especially when your drill or driver simply can't reach. Recently, I had the opportunity to test out DeWalt’s Modular Right Angle System, model DWAMRASETFT. This clever little device promised to ease these frustrations, and after putting it through its paces, I have a mixed bag of insights to share.

Unboxing and First Impressions

From the moment I unpacked the right angle system, it was clear that DeWalt had put significant thought into its design. The compact head height of just 1.5 inches is immediately noticeable, making it apparent this tool is built for those harder-to-reach spots. The metal gearcase promises durability, and the overall heft of the tool suggests a solid build quality.

Versatility and Features

One of the standout features of this tool is its modular capability. It allows for various configurations—Compact Right Angle, Standard Right Angle, Right Angle Flexible Shaft, and Straight Flexible Shaft. This versatility makes it a multi-functional addition to any toolbox. The rare earth magnet integrated into the design is a thoughtful touch, making it easier to handle bits with one hand.

The patented handle design, aimed at minimizing vibration, combined with the long-lasting gears, suggests DeWalt engineered this tool with extended use in mind. This is particularly beneficial when working on longer projects or in situations where precision is crucial.

Performance in Real-World Scenarios

Using the Modular Right Angle System in real-world applications provided mixed results. When attempting to drive screws in tight quarters, the compact head allowed for access that my standard drill simply couldn't achieve. This was particularly useful in cabinetry work, where space is often a premium.

However, one notable drawback is that the attachment rotates freely on the drill. This requires one hand to hold the right angle component steady while the other operates the drill, which can make it cumbersome to get screws started, especially in more confined spaces. This free rotation does allow for an infinite number of drill positions, but at the cost of ease of use.

Quality and Durability

The build quality of the right angle system is generally robust, but not without its flaws. During one project, I noticed some binding issues when the modular extension was attached to the head unit. This friction can make the main input shaft bind excessively, reducing the smoothness of operation. Although this didn’t occur every time, it’s a significant enough issue to warrant mention.

While some users might find the tool feels a bit rough and clunky, particularly when dealing with finished cabinetry where precision and smooth operation are paramount, others may appreciate its durability and rugged feel for more heavy-duty tasks.

Practical Applications

One scenario where this tool shined was in drilling through a floor plate from underneath. Despite my initial skepticism, the tool performed admirably, cutting through the plate effortlessly when paired with my DeWalt XR drill and an Irwin Speedbore bit. This performance was a testament to its capability under strain, proving that when it works, it works well.

That said, the tool’s design does limit its use to hexagonal shaft bits, which could be a limitation for some. It’s also better suited for impact driver use rather than high-RPM drills, which might explain some of the roughness experienced during operation.

Pros and Cons

Pros:
- Versatility: The ability to switch between different configurations makes this tool adaptable to various tasks.
- Compact Design: The 1.5-inch head height allows access to tight spaces.
- Durability: The metal gearcase and overall build quality suggest a long-lasting tool.
- Rare Earth Magnet: Facilitates one-handed bit changes, adding to its convenience.
- Vibration Minimization: The patented handle design does help in reducing vibration, making it more comfortable for extended use.

Cons:
- Free Rotation: The attachment’s free rotation requires two-handed operation, making it less user-friendly in certain situations.
- Binding Issues: The tool can bind when the modular extension is attached, affecting smoothness of operation.
- Hex Bit Limitation: Only accepts bits with hexagonal shafts, which could limit its use for some users.
- Rough Operation: Feels clunky and imbalanced in some applications, particularly in precision tasks.

Final Thoughts and Recommendation

After spending considerable time with the DeWalt Modular Right Angle System, it’s clear this tool has both strengths and weaknesses. It excels in versatility and durability, making it a valuable addition for those who frequently work in tight or awkward spaces. Its compact design and robust build quality are significant advantages.

However, the free rotation of the attachment and occasional binding issues can make it cumbersome and less smooth in operation. If you’re looking for a tool that offers precision and ease of use right out of the box, these factors might be a dealbreaker.

Would I recommend this tool? Yes, but with reservations. For those who need a versatile right angle solution and are willing to navigate its quirks, the DeWalt Modular Right Angle System is a solid choice. However, if you prioritize ease of use and smooth operation above all else, you might want to explore other options.

In conclusion, the DeWalt Modular Right Angle System is a capable tool that can make challenging tasks more manageable. Its versatility and durability are significant selling points, but be prepared to adapt to its unique operational characteristics.
