10 Best Angle Grinders 2025 in the United States

The Milwaukee 2880-20 M18 FUEL Brushless Lithium-Ion Cordless Small Angle Grinder is a strong contender in the angle grinder category, especially for users looking for a powerful and portable tool. With a disc size of 4-1/2 to 5 inches and a robust motor outputting 800 watts, it delivers an impressive maximum rotational speed of 8500 RPM, making it versatile for various grinding tasks. Its lightweight design at just under 5 pounds enhances maneuverability, which is particularly beneficial for prolonged use or precision work.

One of the standout features is the electronic clutch that offers kickback protection, ensuring user safety during operation. Additionally, the overload protection helps extend the motor's lifespan, making this tool a reliable choice for both DIY enthusiasts and professionals. The anti-vibration side handle significantly contributes to user comfort, reducing fatigue during extended periods of use.

Being a tool-only option means you will need to purchase M18 batteries separately, which can be an extra cost if you don’t already own them. While it’s designed for cordless use—which enhances portability—it may also limit run time depending on the battery capacity. Some users may prefer corded models for uninterrupted power, especially for heavy-duty tasks. This angle grinder is designed for those who value portability, safety features, and comfort, suitable for both light tasks around the house and more demanding jobs.

The Milwaukee M18 FUEL 18-Volt Lithium-Ion Brushless Cordless Angle Grinder is designed for those who need a powerful, portable tool for grinding tasks, especially in tight spaces. A standout feature is its 11A corded power capacity, which provides strong performance comparable to corded models, making it suitable for heavy-duty use. The 8500 RPM speed ensures efficient grinding, allowing users to complete tasks quickly. Weighing only 1.2 pounds, it's lightweight, enhancing maneuverability and reducing fatigue during extended use.

The grinder's low profile, flathead design is particularly advantageous for accessing confined areas where traditional grinders struggle. The RAPIDSTOP brake that stops most wheels in under two seconds adds a significant safety feature, helping prevent accidents and injuries during operation.

This grinder is particularly beneficial for DIY enthusiasts or professionals who frequently work in tight spaces, like electricians or plumbers, due to its unique design and safety features. However, if you’re looking for a grinder for heavy-duty work without worrying about battery life, a corded option might be a better fit.

The Makita XAG04Z 18V LXT® Lithium-Ion Brushless Cordless Angle Grinder is a robust option for those who need a versatile and powerful tool. Its brushless motor is efficient and designed for long life, reducing the need for maintenance. The cordless design offers freedom of movement, which is a significant advantage for users working in areas without easy access to power outlets.

The grinder is relatively lightweight at 4.8 pounds, making it easier to handle for extended periods without causing too much fatigue. The disc size compatibility of 4-1/2” to 5” is standard and provides flexibility for different tasks. The maximum rotational speed of 8500 RPM is suitable for most grinding and cutting needs, ensuring efficient performance.

Safety features like the Automatic Speed Change technology and Active Feedback-sensing Technology (AFT) are notable, as they help prevent accidents by adjusting speed and stopping the motor if the wheel is forced to stop suddenly. However, as a tool-only product, it doesn't come with a battery or charger, which means additional costs for those who do not already own compatible Makita batteries. Also, the reliance on battery power means users need to ensure batteries are charged and possibly have spares for longer jobs. Despite these drawbacks, the Makita XAG04Z is a reliable and efficient tool for both DIY enthusiasts and professionals looking for a high-performance cordless angle grinder.
