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 4-1/2 Inch Cordless Angle Grinder is a solid choice for those needing a portable and powerful tool without the hassle of cords. It runs on a 20-volt lithium-ion battery (sold separately), which provides good mobility for jobs in tight or remote spaces. The grinder features a powerful 8,000 RPM motor that can handle both cutting and grinding tasks efficiently, making it suitable for many home improvement or light professional projects. The 4-1/2 inch disc size is common and versatile for various materials.

Weighing about 4.7 pounds, it strikes a good balance between sturdiness and ease of handling. The two-position side handle and two-finger trigger with a lock-off button add comfort and control, which helps reduce fatigue during longer use. Safety is considered with a tool-free guard that lets you quickly adjust the protective cover without tools and a quick-change wheel release simplifying disc swaps. Since this is a bare tool, the battery and charger need to be purchased separately, which adds to the initial cost.

This grinder is well suited for DIYers and professionals who value cordless convenience and decent power in a well-designed package, though some corded grinders may offer higher speeds for very heavy-duty tasks.

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.
