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 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.

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.
