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 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.

The DEWALT Angle Grinder (DWE402) is a powerful tool designed for those who need reliability and performance in their grinding tasks. With an 11 Amp motor that reaches 11,000 RPM, it offers impressive power for various applications, making it suitable for both professional and DIY use. Its lightweight design enhances maneuverability, which is great for extended work sessions. The ergonomic grip and newly designed side handle contribute to user comfort, minimizing fatigue during lengthy projects.

One standout feature is the Dust Ejection System, which effectively removes dust and debris, extending the lifespan of the grinder. This is particularly beneficial for those working in environments where dust accumulation can be a problem. The oversized brushes ensure double the lifespan compared to previous models, which translates into fewer interruptions for maintenance.

However, the DEWALT grinder does have some drawbacks. Its corded design means you are tethered to a power outlet, which may limit your mobility, especially in larger workspaces. Additionally, while the quick-change wheel release is a convenient feature, some users might find it slightly finicky at times. It's also worth noting that while it offers great power, the noise level during operation can be higher than battery-operated models.

In terms of safety, features like the One-Touch Guard for easy adjustment and auto-off brushes that shut down the tool when worn are reassuring for users who prioritize safety. With all these features, the DEWALT Angle Grinder is particularly suitable for those who engage in metalworking or heavy-duty grinding and cutting tasks, but may not be the best fit for casual users looking for a lightweight or battery-powered option.
