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 Makita XAG11T cordless angle grinder is a solid choice if you want a powerful, portable tool for cutting and grinding. It runs on two 18V 5.0Ah lithium-ion batteries, giving you plenty of power and a longer runtime compared to lower-capacity batteries. The brushless motor is a big plus—it runs cooler, lasts longer, and adjusts its speed and torque automatically to match your task, delivering up to 8,500 RPM for efficient cutting and grinding. This means you get strong performance without draining the battery too quickly.

Weighing about 15 pounds with batteries included, it's not the lightest grinder, so it might feel a bit heavy during extended use, but its compact design and included side handle help with control and comfort. Safety features are well thought out: the electric brake stops the wheel in 2 seconds, reducing risk after finishing a cut, and the Active Feedback-sensing Technology cuts power if the wheel suddenly stalls, protecting you from kickback. The kit comes fully loaded with two batteries, a rapid charger, grinding and cut-off wheels, wheel guards, and a contractor bag, which is great value if you need all these accessories.

The relatively heavier weight and the 4-1/2” /5” disc size limit might not suit heavy-duty jobs that require bigger discs or extended periods of use without fatigue. For general cutting and grinding tasks around the home or job site, this Makita model offers excellent power, safety, and convenience.
