Overview of the DEWALT Angle Grinders

When it comes to cordless angle grinders, the DEWALT 20V MAX* XR Angle Grinder with Brake and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder are two excellent options. The XR model is priced at $222.51, while the FLEXVOLT ADVANTAGE model is about 35% cheaper, coming in at $144.50. Both tools are designed to handle tough tasks, but they each have distinct features that appeal to different needs.

Performance Power

The DEWALT FLEXVOLT ADVANTAGE Angle Grinder offers up to 54% more power when used with FLEXVOLT batteries compared to standard 20V MAX* batteries. This feature enables it to deliver a maximum output of 1,550 watts and reach speeds of up to 9,000 RPM, making it a powerhouse for demanding jobs. In contrast, the DEWALT 20V MAX* XR Angle Grinder provides robust performance with a brushless motor, but it does not emphasize an increase in power with specific battery types. Instead, it focuses on safety features like a brake that stops the wheel in 2 seconds or less.

Safety Features

Safety is crucial when using angle grinders, and both models come equipped with advanced safety features. The DEWALT 20V MAX* XR Angle Grinder includes a Kickback Brake that halts the wheel in emergencies, while its POWER-LOSS RESET prevents accidental startups after power outages. On the other hand, the FLEXVOLT ADVANTAGE model features an E-CLUTCH that shuts down the motor within a tenth of a second during a pinch or stall, providing an additional layer of protection. Both tools prioritize user safety, but the FLEXVOLT ADVANTAGE offers more rapid response time in critical situations.

Versatility and Compatibility

Both grinders are compatible with DEWALT 20V MAX* batteries, but the FLEXVOLT ADVANTAGE model also accommodates FLEXVOLT batteries, adding versatility for users who already own these higher-capacity batteries. This feature makes the FLEXVOLT ADVANTAGE particularly appealing to professionals looking to maximize their tool investment. In contrast, the DEWALT 20V MAX* XR Angle Grinder is optimized for users seeking a straightforward, efficient tool without the need for additional battery types.

Design and Usability

The DEWALT 20V MAX* XR Angle Grinder features a flathead design, which allows for better access in tight spaces, making it ideal for detailed work. Its paddle switch design enhances user control during operation. The FLEXVOLT ADVANTAGE, while not specifically designed for tight spaces, offers a paddle switch as well and is user-friendly, making it easy to operate for extended periods. Both designs prioritize comfort and usability, but the XR model may offer a slight edge for intricate tasks.

Pricing Comparison

The pricing difference between the two models is significant, with the FLEXVOLT ADVANTAGE retailing for $144.50 and the XR model priced at $222.51. This means that the FLEXVOLT ADVANTAGE is about 35% less expensive, making it a more attractive option for budget-conscious consumers. However, the higher price of the XR model may be justified by its unique safety features and specialized design for tight spaces, depending on user needs.

Sales and Popularity

In terms of popularity, the DEWALT FLEXVOLT ADVANTAGE holds a better sales rank at 14,755 compared to the DEWALT 20V MAX* XR Angle Grinder, which has a rank of 77,304. This indicates a greater demand and potentially more positive user feedback for the FLEXVOLT model. Given its favorable sales ranking, it might indicate a higher level of customer satisfaction and trust in its performance.

Which should you buy?

Ultimately, the choice between the DEWALT 20V MAX* XR Angle Grinder and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder depends on your specific needs. If you prioritize safety features and require a tool for tight spaces, the XR model may be worth the extra investment. However, if you’re looking for a more powerful option at a lower price and have the flexibility of using FLEXVOLT batteries, the FLEXVOLT ADVANTAGE is a compelling choice. Both grinders excel in their own right, making them strong contenders in the angle grinder market.
