DeWalt 6 in. (150mm) Trigger-Switch Grinder with No Lock-On

Grinders are essential tools in any workshop, and finding one that balances power, durability, and ease of use can be challenging. Recently, I had the opportunity to work with DeWalt’s 6 in. Trigger-Switch Grinder with No Lock-On, model DWE43066N. This grinder is specifically designed for metal grinding and cutting applications and boasts a 13 Amp motor that delivers a commendable 9,000 RPM. Here’s my comprehensive take on how this tool performed in a real-world setting.

First Impressions

Straight out of the box, the DeWalt grinder feels solid and well-constructed. Its weight is balanced well enough to give a sense of reliability without becoming cumbersome during prolonged usage. The design is sleek yet functional, with a pronounced emphasis on safety features. The trigger-switch mechanism with the safety lock is a welcomed addition, ensuring that accidental startups are less likely.

Performance and Power

The grinder’s 13 Amp motor is undoubtedly powerful, capable of handling a variety of metal grinding and cutting tasks with ease. During my tests, the tool demonstrated a robust performance, especially when cutting through thick metal sheets and grinding down welds. There is a noticeable soft start feature that ramps up the RPM over a couple of seconds after pulling the trigger. Initially, this felt unusual, but it quickly became apparent that this feature reduces the initial torque feedback, making the startup smoother and less jarring.

Safety and Durability

One of the standout features of this grinder is the Anti-Rotation E-CLUTCH® System. This system kicks in when a pinch or stall is detected, shutting down the motor to prevent potential kickbacks. This is an invaluable safety feature, especially for those who work in environments where unexpected stalls are a common occurrence. The tool also includes a Dust Ejection System™ that expels dust and debris from the intake vents, which significantly prolongs the life of the grinder by preventing dust from clogging the motor.

Another practical feature is the Power Loss Reset®. This prevents accidental restarts following a power interruption, which is a crucial safety measure in busy work environments. The grinder also features a tool-free guard adjustment, making it incredibly convenient to make quick changes without needing additional tools.

Ergonomics and Ease of Use

The grinder is designed with user comfort in mind. The precision grip is ergonomic, which is particularly beneficial for extended use, especially for individuals with conditions like arthritis. The tool’s weight and balance feel just right, not too heavy to cause fatigue nor too light to feel flimsy. However, the handle could be more robust, as it felt a bit cheap and didn’t inspire the same confidence as the rest of the tool.

One minor issue I encountered was with the noise level. The grinder is quite loud, which isn’t unusual for a tool of this nature, but it's worth noting for those working in noise-sensitive environments.

Areas for Improvement

Despite its many strengths, the DeWalt grinder isn’t without its flaws. The lack of a variable speed feature might be a drawback for some users who require more control over their grinding applications. The grinder operates at a constant 9,000 RPM, which is suitable for most tasks but might not offer the finesse needed for more delicate work.

Another concern is the longevity of the grinder under heavy industrial use. While it performed admirably in my tests, there were some reports of the grinder developing issues after extended use, such as unusual noises and oil leakage. This could be a point of concern for those looking to invest in a tool that needs to withstand rigorous, daily use.

Versatility and Applications

This grinder excels in a variety of applications, including metal cutting, grinding, and even some masonry work. It’s versatile enough to handle different materials and tasks, making it a valuable addition to any workshop. The ability to switch between different guard sizes from 4” to 6” adds another layer of versatility, allowing users to customize the tool to their specific needs.

Final Thoughts

In conclusion, the DeWalt 6 in. Trigger-Switch Grinder with No Lock-On (DWE43066N) is a powerful, reliable tool with several innovative safety features that make it a standout in its category. Its 13 Amp motor delivers impressive performance, and the soft start feature, anti-rotation system, and dust ejection system collectively enhance its usability and longevity.

That being said, the lack of variable speed and some concerns about its durability under heavy use are worth considering. For professional users who need a grinder that can handle a variety of tasks with robust safety features, this DeWalt model is a solid option. However, for those requiring more nuanced control or using the tool in extremely demanding industrial settings, it might be worth exploring other options or keeping a backup handy.

Overall, I would recommend the DeWalt DWE43066N for its power, safety features, and ease of use. It’s a great tool for anyone from DIY enthusiasts to professional welders, provided they are aware of its limitations and use it within its designed capabilities.
