Overview of the DEWALT Angle Grinders

The DEWALT Angle Grinder is available in two distinct models: the DEWALT Angle Grinder (DW840) and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder (DCG416B). Each grinder caters to different needs, making them suitable for various tasks. The DW840 has a price of $166.02, while the DCG416B is priced at $144.50, making the latter approximately 17% cheaper.

Power and Performance Comparison

When it comes to power, the DEWALT Angle Grinder (DW840) is equipped with a robust 13 Amp motor, delivering speeds of up to 8,000 RPM. This makes it an ideal option for heavy-duty grinding and cutting applications. In contrast, the DEWALT FLEXVOLT ADVANTAGE (DCG416B) boasts a brushless motor that provides up to 54% more power when paired with FLEXVOLT batteries, reaching a maximum speed of 9,000 RPM. Thus, while the DW840 excels in its traditional corded performance, the DCG416B offers enhanced versatility with its battery compatibility, making it suitable for on-the-go tasks.

Design and Usability

In terms of design, both grinders feature user-friendly attributes. The DW840 has an adjustable guard that can redirect sparks away from the user, enhancing safety during operation. It also includes a spindle lock for quick wheel changes. The DCG416B, on the other hand, includes a paddle switch that allows for easier operation, especially in tight or awkward spaces. It also features E-Switch Protection, which prevents accidental start-ups after a power outage. While both grinders offer great usability, the DCG416B's design may provide more convenience for users working in varied environments.

Safety Features

Safety is paramount when using power tools, and both models prioritize this aspect. The DW840 features a guard that can be adjusted to redirect sparks away from the user, ensuring a safer working environment. Additionally, it has sealed ball and roller bearings to protect against debris. The DCG416B takes safety a step further with its Kickback Brake that stops the wheel quickly in case of a bind-up, and the E-CLUTCH system that shuts down the motor within a tenth of a second during a pinch or stall. These advanced safety mechanisms make the DCG416B particularly appealing for those concerned about workplace safety.

Versatility and Battery Life

The versatility of the DEWALT FLEXVOLT ADVANTAGE (DCG416B) shines through its compatibility with all DEWALT 20V MAX* and FLEXVOLT batteries. This feature allows users to switch between tools without the need for multiple battery types, enhancing efficiency on the job site. Meanwhile, the DW840's corded design ensures consistent power supply but limits mobility. For users who require flexibility and portability in their tools, the DCG416B is the clear choice, but for those who prefer the reliability of a corded tool, the DW840 remains a formidable option.

Price and Value

Analyzing the price point, the DEWALT FLEXVOLT ADVANTAGE (DCG416B) is priced at $144.50, making it a more budget-friendly option compared to the $166.02 price tag of the DEWALT Angle Grinder (DW840). This price difference of about $21.52 could be significant for budget-conscious consumers. However, it’s essential to consider the value each grinder brings to the table. The DW840's robust features and powerful motor may justify the higher price for users who need a reliable, heavy-duty tool, while the DCG416B offers exceptional power and features for a lower investment.

Sales and Popularity

When it comes to sales ranks, the DEWALT FLEXVOLT ADVANTAGE (DCG416B) holds a better position at 14,755 compared to the DW840's rank of 60,043. This indicates that the DCG416B is currently more popular among consumers, likely due to its modern features and versatility. The popularity of the DCG416B may reflect a growing preference for battery-powered tools, aligning with trends in the power tool market.

Which should you buy?

In conclusion, the choice between the DEWALT Angle Grinder (DW840) and the DEWALT FLEXVOLT ADVANTAGE (DCG416B) largely depends on the user's specific needs. If you prioritize power and heavy-duty performance, the DW840 is a solid choice with its strong corded motor. However, if versatility, safety, and a lower price point are more critical for your tasks, the DCG416B stands out with its advanced features and battery compatibility. Ultimately, both grinders offer unique benefits, ensuring that there is a suitable option for every type of user.
