Overview of the Products
In the comparison between the DEWALT Angle Grinder Tool and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder, the latter is the more cost-effective choice, priced at $144.50 compared to the former's $158.99. While both products are designed for high performance, they cater to slightly different user needs and preferences, which are important to consider when making a selection.
Design and Build Quality
Both the DEWALT Angle Grinder Tool and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder are built with durability in mind. The DEWALT Angle Grinder Tool features a lightweight design at 5.7 lbs, making it easy to handle for extended periods. In contrast, the FLEXVOLT ADVANTAGE model is designed for power and versatility, with the added benefit of being compatible with both 20V MAX* and FLEXVOLT batteries. This opens up more options for users, especially those who already own DEWALT batteries.
Motor Performance
When it comes to motor performance, the DEWALT Angle Grinder Tool is equipped with a robust 13 Amp motor that delivers a reliable 9,000 RPM rating. On the other hand, the FLEXVOLT ADVANTAGE model boasts a brushless motor that can produce up to 54% more power when paired with a FLEXVOLT battery. This means that users looking for maximum efficiency may prefer the FLEXVOLT model, especially those who plan to use it for heavy-duty tasks.
Safety Features
Safety is a key consideration in power tools, and both models offer distinct features. The DEWALT Angle Grinder Tool includes a Dust Ejection System that protects the motor from damaging debris. Conversely, the DEWALT FLEXVOLT ADVANTAGE model is equipped with advanced safety features like a Kickback Brake that stops the wheel quickly in the event of a bind-up and an E-CLUTCH system that shuts down the motor in a pinch/stall situation. This makes the FLEXVOLT ADVANTAGE model a better choice for users concerned about safety during operation.
Included Accessories
Both grinders come with essential accessories to enhance their functionality. The DEWALT Angle Grinder Tool includes a side handle, multiple guards, and flanges, providing users with everything needed to get started right out of the box. The FLEXVOLT ADVANTAGE model, while marketed as "tool only," is designed for those who may already have compatible batteries and chargers. This could be a drawback for users needing a complete kit upon purchase.
Usability
In terms of usability, both grinders shine in their own right. The DEWALT Angle Grinder Tool is straightforward with its trigger switch, making it easy to operate. The FLEXVOLT ADVANTAGE model, with its paddle switch, offers a different user experience, which some may find more comfortable, especially during prolonged use. Both models are designed for ease of use, but the choice between a trigger and paddle switch could influence user preference.
Sales Rank and Market Position
Analyzing the sales rank, the DEWALT Angle Grinder Tool has a bestseller rank of 24,177, while the FLEXVOLT ADVANTAGE model ranks higher at 14,755. This suggests that the FLEXVOLT ADVANTAGE may have a stronger market presence and could be more appealing to consumers, potentially due to its innovative features and better power efficiency when using FLEXVOLT batteries.
Price and Value
The DEWALT Angle Grinder Tool retails for $158.99, while the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder is priced at $144.50, making it approximately 9% cheaper. This price difference could be significant for buyers on a budget, especially considering the FLEXVOLT model’s superior power capabilities when paired with the right battery. Therefore, for users seeking value without compromising on performance, the FLEXVOLT ADVANTAGE may offer a more attractive deal.
Which should you buy?
Deciding between the DEWALT Angle Grinder Tool and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder ultimately depends on your specific needs. If you prioritize a lightweight design and included accessories, the DEWALT Angle Grinder Tool may be the better option. However, if you are looking for enhanced power, advanced safety features, and a lower price point, the FLEXVOLT ADVANTAGE model is likely the superior choice. Consider your usage and preferences carefully to make an informed decision.
