DEWALT Angle Grinder DW840 review powerful 13-Amp tool with dust ejection system

Description

Reliable Performance with the DEWALT DW840 Angle Grinder

I’ve spent a good amount of time working with the DEWALT DW840 Angle Grinder, and it’s safe to say this tool both impressed and surprised me. Designed for heavy-duty operations, this 7-Inch, 13-Amp grinder is a beast when it comes to power. Whether I’m cutting, grinding, or smoothing different materials, this machine handles the task with ease. That said, there are some aspects you might want to weigh before investing.

Powerful Motor and High RPM

One of the key benefits of this grinder is its 13-amp motor, which delivers a solid 8,000 RPM. This means it doesn’t bog down, even when handling tough materials like thick metal or rough concrete. I put it to work on a steel pipe project, and the grinder didn’t flinch. Its 3.02 horsepower ensures that it can tackle demanding tasks without overheating. For anyone who needs consistent performance, this feature is a game changer.

• High rotational speed makes it effective for various tasks.
• Cuts through heavy-duty materials like butter.
• Motor durability ensures long-term use in tough conditions.

Dust Ejection System: A Thoughtful Addition

What really stood out to me was the Dust Ejection System. Dust and debris are major issues when using angle grinders, often causing wear and tear over time. However, this system does a great job of keeping the internals protected. During some grinding on concrete, I noticed far less dust accumulation than with other models I’ve used. This feature not only extends the tool’s lifespan but also makes for a cleaner workspace.

Ergonomic Design and Build Quality

The classic DEWALT design with its yellow and black plastic-metal body feels sturdy yet comfortable in hand. At 12.1 pounds, it’s on the heavier side, but that weight adds to its stability during use. The side handle is adjustable, which is a blessing for both left and right-handed users. I found it easy to switch positions depending on the angle I needed, and the grip itself is solid with minimal slippage. However, the size might be cumbersome for someone with smaller hands.

• Side handle adjustability improves maneuverability.
• Sturdy build ensures it holds up to wear and tear.
• Weight provides stability but could tire users during prolonged tasks.

Included Accessories Make It Ready to Use

The grinder comes with a set of handy components, including a 7-inch wheel, Type 27 guard, side handle, and even a hex key for quick adjustments. The spindle-lock button simplifies wheel changes, which I found incredibly convenient while switching between cutting and grinding tasks. You don’t need a second wrench, which is a small but significant time-saver.

Key Benefits

• Dust Ejection System prolongs the tool’s life.
• Versatile AC/DC power compatibility for various settings.
• Spindle-lock button simplifies wheel changes.
• Comes with a complete accessory kit for immediate use.

Areas for Improvement

Like most tools, the DEWALT DW840 isn’t without its flaws. While it’s a powerhouse, there are a few adverse aspects worth noting:

• The 12.1-pound weight can be tiring for extended use.
• No variable speed options, which limits control for more delicate tasks.
• The guard adjustment could be smoother; it occasionally feels stiff.

Competitive Options

Comparing the DEWALT DW840 to other popular models like the Makita GA7021 or the Bosch 1974-8, it holds its own in terms of power and durability. The Makita offers a slightly higher RPM at 8,500, but its dust management isn’t as effective. On the other hand, the Bosch grinder is slightly lighter, making it a better option for prolonged use. However, neither competitor matches DEWALT’s robust accessory set and overall toughness.

• Makita GA7021: Higher RPM but lacks efficient dust control.
• Bosch 1974-8: Lighter weight but comes with fewer accessories.
• DEWALT DW840: Best for heavy-duty tasks and durability.

Cost-Effectiveness

This grinder gives you a great price-to-quality ratio, considering its powerful motor, dust ejection system, and all the included accessories. While it’s not the cheapest option on the market, the durability and performance make it worth the investment. I’d recommend it especially for contractors or DIY enthusiasts who need a reliable tool for demanding tasks. If you’re looking for something lightweight or with more speed control, however, you may want to explore other options.
