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 2889-20 M18 angle grinder is designed to cater to a variety of grinding tasks with its versatile features and specifications. One of its key strengths is the variable speed setting, offering five different speeds ranging from 3,500 RPM to 8,500 RPM. This flexibility allows for greater control and precision depending on the task at hand. The braking system is another notable feature, efficiently stopping most wheels in less than 2 seconds, which enhances safety during use.

Additionally, the tool-free guard adjustment and accessory changes with FIXTEC Nut Technology make it user-friendly and convenient, allowing for quick and hassle-free setup and modifications. The slide switch is designed to reduce user fatigue, further emphasizing the importance of user comfort in its design. Weighing only 1 pound, this grinder is quite lightweight, which makes it easy to handle and maneuver, although some users might find it lacking heft for more heavy-duty tasks.

One potential downside is that batteries are not included, and it can be powered by electric, gas, or battery, requiring additional purchases for a complete setup. This can be inconvenient for users looking for an all-inclusive package. The grinder's power output is 158 watts, which should suffice for most general purposes but might not be enough for more demanding, high-power applications. The product’s corded or cordless versatility is a bonus, offering flexibility based on user preference. For those in need of a reliable and user-friendly angle grinder for various tasks, the Milwaukee 2889-20 M18 is a solid choice, particularly for those who value speed control and ease of use.

The Metabo 4.5In / 5In Angle Grinder stands out as a durable and powerful tool, designed with German engineering. Its 11.0 Amp motor delivers robust performance with 11,000 RPM, making it suitable for demanding metal grinding and masonry cutting tasks. The maximum rotational speed, however, is listed at 7500 RPM which may be a bit confusing. The grinder's compact design and smallest handle circumference in its class ensure comfortable usage, with the non-locking paddle switch adding a layer of safety by requiring continuous pressure to operate.

Weighing 6 pounds, it is relatively easy to handle but may be heavy for extended use. The corded power source ensures consistent energy without the need to recharge batteries, which can be beneficial for prolonged tasks. The S-automatic Torque Limiting Clutch feature reduces the risk of kickback, enhancing user safety further. On the downside, being corded limits mobility compared to cordless models.

The grinder's versatility is enhanced by the ability to mount the gear housing in 90° steps for left-handed use. This angle grinder is ideal for professionals who need a reliable, safe, and ergonomic tool for heavy-duty tasks. However, it might not be the best choice for those who prioritize lightweight, portable options.
