10 Best Dewalt Grinders 2025 in the United States

The DEWALT 20V MAX Angle Grinder (DCG413B) is a solid choice for those looking for a powerful and versatile tool for grinding tasks. Its brushless motor enhances efficiency and eliminates the need for brush changes, making maintenance easier. The grinder operates at a maximum speed of 3450 RPM, ideal for various grinding applications, and its lightweight design (3.75 pounds) makes it easy to handle during extended use.

One of the standout features is its safety mechanisms. The electronic brake stops the wheel quickly, which can prevent accidents and injuries. Additionally, the kickback brake and E-Switch protection further enhance safety by minimizing unexpected starts and stops. This is particularly beneficial for DIYers and professionals alike who prioritize safety while working.

However, there are some considerations to keep in mind. As a tool-only option, it does not come with a battery or charger, which means users will need to purchase these separately if they don't already have them. This could be an added cost for those just starting their tool collection. Furthermore, while the grinder is powerful, its 4-1/2 inch disc size may be limiting for more extensive projects requiring larger discs.

The DEWALT FLEXVOLT ADVANTAGE 20V MAX Angle Grinder is a strong contender in the battery-powered grinder category, particularly appealing to those who require a tool for cutting and grinding tasks without the hassle of cords. One of its standout strengths is its ability to deliver up to 54% more power when paired with FLEXVOLT batteries, enhancing performance for demanding jobs. This feature makes it a great option for both professional contractors and DIY enthusiasts looking for robust capabilities.

Safety is a key focus in this model, boasting features like the Kickback Brake, which rapidly stops the wheel in case of a bind-up, and the E-CLUTCH, designed to shut down the motor promptly if a stall is detected. These mechanisms provide added peace of mind for users, especially those who may not be as experienced with power tools.

In terms of ergonomics, the grinder is designed to be relatively lightweight and easy to handle, which can be beneficial during extended use. It's compatible with DEWALT's 20V MAX and FLEXVOLT batteries, offering versatility for users who already own other DEWALT tools. While it excels in power, the fact that it is a tool-only option means users will need to invest in batteries and a charger separately, which could increase initial costs. Moreover, while the Tool Connect feature adds some technological convenience, it's an optional add-on, meaning users must purchase it separately to enjoy that benefit. This may not be essential for everyone, especially those who prefer a straightforward tool without smart features. This angle grinder serves as a solid choice for those needing a reliable, powerful tool for grinding and cutting tasks, particularly in professional or heavy-duty contexts.

The DEWALT 20V MAX* XR Angle Grinder (DCG405B) is a powerful and versatile tool that runs on a battery, making it convenient for use in various locations without the need for a power outlet. Its brushless motor is a standout feature, as it requires no brush changes, which means less maintenance and a longer lifespan. The grinder uses a 4-1/2-inch disc, a common size for a variety of grinding and cutting tasks. With its high RPM, it can handle tough jobs efficiently.

The tool's ergonomics are designed for user comfort with dimensions of 12.9 inches in length and 6.3 inches in width, making it relatively easy to handle, though some might find it slightly bulky. Weighing in at around 4.9 pounds, it balances well between being lightweight and sturdy. Safety is a priority with this model, featuring a Kickback Brake that quickly stops the wheel in case of a pinch or stall, reducing the risk of accidents. The Power Loss Reset feature prevents accidental restarts after a power interruption, adding another layer of safety.

This tool is best suited for professional users or serious DIY enthusiasts who need reliable, portable grinding power. One potential drawback is that it is sold as a 'tool only' product, meaning the battery and charger are not included and must be purchased separately. This could add to the cost, especially for first-time buyers who do not already own compatible DEWALT batteries.
