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 20V MAX* XR Brushless Cordless Grinder is a strong contender in the angle grinder category, offering a battery-powered operation that provides the convenience of cordless use. This grinder features a robust brushless motor delivering up to 1,640 MWO and a no-load speed of 9,000 RPM. The variable speed functionality is a big advantage as it allows users to adjust the wheel speed to suit different materials, ensuring optimal performance across a range of tasks.

The disc size flexibility between 4-1/2 inches and 5 inches also adds to its versatility for various cutting and grinding jobs. Weighing in at 4.92 pounds, the grinder is relatively lightweight and ergonomically designed, making it easier to handle and reducing user fatigue during extended use. The anti-rotation system, which shuts down the tool if excessive rotational motion is detected, is an important safety feature that enhances user safety.

Additionally, the tool is compatible with the TOOL CONNECT system for asset management, although the chip is sold separately. One potential drawback is that the grinder is sold as a tool only, so users will need to purchase batteries and chargers independently if they don’t already own compatible DEWALT products. Furthermore, the wireless tool control system for pairing with a dust extractor requires additional purchases, which might be a downside for some users. This grinder is well-suited for professionals and serious DIY enthusiasts looking for a powerful, versatile, and safe cordless grinder.

The DEWALT 20V MAX Cordless 4 1/2 Inch Grinder (DCG408B) is a battery-powered tool designed for portability and convenience without sacrificing performance. Its brushless motor provides up to 850 MWO and spins discs at a high speed of 9,000 RPM, making it powerful enough for cutting and grinding tasks like rebar cutting. The 4 1/2 inch disc size is a common and versatile choice, suitable for a wide range of general metalwork and construction jobs. Weighing just 3.55 pounds (bare tool), it's lightweight and ergonomic, which helps reduce user fatigue during extended use. Safety is well-addressed with features like a Kickback Brake and E-Clutch to prevent sudden tool movement and increase control.

As a bare tool, it requires purchasing the battery and charger separately, which could add to the initial cost. The battery life allows for around 56 cuts on 1/2-inch rebar, which is decent but might limit longer jobs without spare batteries. This grinder is a good fit for DIYers and professionals needing a cordless, easy-to-handle grinder for medium-duty tasks, especially where portability is important. It is less ideal for heavy industrial use that demands longer continuous run time or larger disc sizes.
