10 Best Dewalt Grinders 2026 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 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.

The DEWALT 20V MAX XR Brushless Cordless Angle Grinder offers a solid option for those needing a portable grinder without the hassle of cords. Powered by a 20-volt battery (sold separately), it packs a punch with a brushless motor delivering up to 1 horsepower and speeds reaching 9,000 RPM, making it capable of handling tough grinding or cutting tasks. The grinder supports 4-1/2 to 5-inch discs, which is a common and versatile size for many jobs around the workshop or job site.

Weighing just under 4.6 pounds, it balances power with manageable weight, helping reduce user fatigue during extended use. Its design includes an anti-rotation safety system that shuts the tool off if it detects excessive spin, adding an important layer of protection. The tool also features compatibility with DEWALT’s TOOL CONNECT system for wireless asset tracking and remote control, which is helpful for keeping tabs on your tools but requires additional purchases like the chip and dust extractor.

This grinder is well suited for professionals or serious DIYers who value cordless freedom, powerful performance, and extra safety features in a robust, easy-to-handle package. Keep in mind that the battery and charger are not included, so you’ll need to invest in those separately if you don’t already own compatible DEWALT 20V MAX batteries.
