10 Best Cordless Angle Grinder 2025 in the United States

The DEWALT 20V MAX Angle Grinder (DCG413B) stands out in the cordless angle grinder category, especially for users looking for a reliable and powerful tool. It features a brushless motor which enhances efficiency and longevity, eliminating the need for frequent maintenance like brush replacements. With a no-load speed of 3450 RPM, it delivers strong performance for grinding tasks. The grinder's weight of just 3.75 pounds makes it relatively lightweight, offering good maneuverability during use.

One of the notable strengths is its safety features. The electronic brake stops the wheel in two seconds or less, reducing the risk of accidents. Its kickback brake activates during unexpected situations, providing an extra layer of security. The E-Switch Protection helps prevent accidental restarts, which is a great feature if you’re concerned about safety during power interruptions.

However, there are some considerations to keep in mind. This tool does not include a battery, which means you will need to purchase one separately if you don’t already own a DEWALT 20V battery. While it’s designed for heavy-duty tasks, users may find its disc size of 4-1/2 inches limiting for larger jobs. Additionally, while the two-stage trigger is an important safety feature, it may take some getting used to for those who prefer a more straightforward operation.

In terms of ergonomics, it has a comfortable design that helps reduce fatigue during extended use, making it a solid choice for both DIY enthusiasts and professionals. If you’re looking for a portable, efficient angle grinder for various grinding tasks, the DEWALT 20V MAX is a great option, assuming you take into account the additional battery purchase.

The Milwaukee 2880-20 M18 FUEL Cordless Angle Grinder is a solid choice for users looking for a powerful and portable tool for grinding tasks. With an 800-watt brushless motor, it offers a maximum no-load speed of 8,500 RPM, making it efficient and capable of handling a variety of materials. The grinder is compatible with all M18 batteries, allowing for flexibility, although you will need to purchase the battery separately if you don’t already own one.

One of its standout features is the electronic clutch, which helps protect against kickback, enhancing safety during use. Additionally, it includes overload protection to prolong the motor's lifespan. The anti-vibration side handle contributes to user comfort, making it easier to use for extended periods without causing strain.

In terms of ergonomics, this grinder weighs about 4.99 pounds, which is relatively light for a tool of this power, but some users might find it slightly heavier during prolonged use. The 5/8”-11 spindle allows for compatibility with common grinding accessories, making it versatile for different tasks. Potential buyers should keep in mind that this model is sold as a tool-only unit, meaning batteries and chargers are not included. This could be a drawback for those looking for an all-in-one package.

The DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder is a solid choice for both hobbyists and professionals looking for a cordless solution. One of its standout features is the compatibility with both 20V MAX* and FLEXVOLT batteries, which allows for increased power—up to 54% more when paired correctly. This is particularly beneficial for users who need a reliable tool for heavier tasks, as the additional power can make cutting and grinding more efficient.

Safety is a priority with this angle grinder. The Kickback Brake and E-CLUTCH features are designed to protect users from sudden wheel stoppages and motor stalls, which is essential for maintaining control during operation. The E-Switch Protection adds another layer of safety by requiring the trigger to be reset after a power outage, reducing the risk of accidental starts.

In terms of ergonomics, the paddle switch design enhances comfort, making it easier to operate over extended periods. However, its weight is something to consider; while it's not excessively heavy, users looking for a lightweight tool may find it slightly cumbersome after prolonged use. The no-load speed and disc size of 4-1/2 to 5 inches cater well to a variety of tasks, whether you're grinding, cutting, or polishing. As a tool-only offering, buyers must remember to purchase batteries and chargers separately if they do not already own compatible DEWALT products.

One drawback is the lack of a brushless motor, which can provide longer run times and less maintenance compared to brush motors. This might be a consideration for users who prioritize these features in their tools. Additionally, while the Tool Connect compatibility is a nice touch for job site management, the chip is sold separately, which could add to the overall cost.

This angle grinder is well-suited for users who value power, safety, and ergonomic design, making it a worthwhile investment for various grinding applications.
