For years, I struggled with inefficient angle grinders, leaving me frustrated and with less-than-perfect results on my DIY projects. The thought of tackling a challenging project often felt daunting, knowing the limitations of my old equipment. A reliable, powerful angle grinder like the DEWALT DW840 Angle Grinder would have saved me countless hours and headaches.
Angle grinders are indispensable tools for various tasks, from cutting metal and grinding welds to sharpening tools and removing rust. However, the market is flooded with options, making the selection process challenging. The ideal customer is someone who needs a powerful and versatile tool for frequent use in demanding applications. Someone primarily tackling light-duty tasks might find a less powerful, smaller grinder sufficient and more budget-friendly. For infrequent use, a less expensive model might suffice. Before buying, consider factors like the motor’s power (measured in amps), the speed (RPM), the size of the grinding wheel, the weight and balance of the tool, safety features (like dust ejection systems and adjustable guards), and the overall build quality. A robust, well-balanced grinder is less prone to fatigue and more manageable for extended periods.

Exploring the DEWALT DW840’s Key Features and Benefits
Unrivaled Power and Performance
The 13-amp motor of the DEWALT DW840 is the heart of this machine. It effortlessly cuts through thick metal, grinds welds smoothly, and handles various other demanding tasks without slowing down. The high 8,000 RPM ensures efficient material removal, minimizing the time spent on each job. This power is crucial for completing projects quickly and efficiently, especially when working on large-scale jobs. My old grinder constantly struggled with tougher materials, leading to frustration and increased project time. The DW840 completely changed that equation.
Safety First: The Importance of the Adjustable Guard and Dust Ejection
Safety is paramount when using any power tool. The DEWALT DW840’s adjustable guard is a lifesaver. It allows you to direct sparks and debris away from yourself, significantly reducing the risk of injury. This feature is a considerable upgrade from earlier models where guard adjustment was more cumbersome. The integrated dust ejection system, while not perfect, helps to keep your work area cleaner and improves visibility, leading to a more precise and safer working experience. Without this, my workspace quickly becomes cluttered and dusty, hindering my progress.
Effortless Wheel Changes: Spindle Lock and Single-Wrench System
Changing grinding wheels on many angle grinders can be a tedious and time-consuming process. However, the DEWALT DW840 makes it a breeze with its convenient single-wrench wheel change system and spindle lock. This feature saves valuable time between tasks, enhancing overall productivity. I’ve spent far too much time wrestling with less user-friendly systems on other grinders. The simplicity of the DW840’s system is a huge advantage for efficiency.
Ergonomics and Durability: Designed for Comfort and Longevity
The DEWALT DW840 is built to last. Its robust construction, combined with its relatively balanced design, minimizes fatigue during extended use. While it’s not the lightest grinder on the market, the weight is well-distributed, making it manageable even for extended periods. Many cheaper grinders I’ve used felt flimsy and poorly balanced, resulting in discomfort and increased risk of accidents. The quality and weight of this tool are a testament to its value.
