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.

Never use my corded grinder anymore! This Makita is great!

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.

Buying Guide for the Best Angle Grinders

Angle grinders are versatile tools that can be used for a variety of tasks, including cutting, grinding, polishing, and sanding. When choosing an angle grinder, it's important to consider the specific tasks you plan to use it for, as well as the features that will make the tool most effective and comfortable for you. Understanding the key specifications will help you make an informed decision and select the best angle grinder for your needs.
Disc SizeThe disc size of an angle grinder determines the size of the cutting or grinding area. Common sizes include 4.5 inches, 6 inches, and 9 inches. Smaller discs are suitable for precision work and lighter tasks, while larger discs are better for heavy-duty jobs and cutting through thicker materials. Choose a disc size based on the type of work you plan to do most often.
Power (Amps or Watts)The power of an angle grinder is measured in amps (for corded models) or watts (for cordless models). Higher power ratings mean the grinder can handle tougher materials and more demanding tasks. For light to medium tasks, a grinder with 5-7 amps (or 500-700 watts) should suffice. For heavy-duty work, look for a grinder with 8-12 amps (or 800-1200 watts). Consider the intensity and frequency of your work when choosing the power level.
Speed (RPM)The speed of an angle grinder is measured in revolutions per minute (RPM). Higher RPMs allow for faster cutting and grinding, but may also generate more heat and require more control. Typical speeds range from 5,000 to 10,000 RPM. For general use, a grinder with 7,000-9,000 RPM is usually sufficient. If you need more precision or are working with delicate materials, a lower speed may be preferable.
WeightThe weight of an angle grinder affects how comfortable it is to use, especially for extended periods. Lighter grinders (4-6 pounds) are easier to handle and maneuver, making them suitable for overhead or precision work. Heavier grinders (7-10 pounds) provide more stability and are better for heavy-duty tasks. Consider the duration and type of work you will be doing to choose a weight that you can comfortably manage.
Safety FeaturesSafety features on angle grinders can include adjustable guards, anti-kickback mechanisms, and vibration reduction. These features help protect you from debris, accidental starts, and excessive vibration, which can lead to fatigue or injury. Look for grinders with robust safety features, especially if you are new to using power tools or plan to use the grinder frequently.
Handle DesignThe handle design of an angle grinder can impact your comfort and control. Some grinders have adjustable or removable side handles, which can be positioned for left or right-handed use. Ergonomic handles with soft grips can reduce fatigue and improve control. Choose a handle design that feels comfortable in your hand and allows you to maintain a secure grip during use.
Corded vs. CordlessAngle grinders come in both corded and cordless models. Corded grinders offer consistent power and are ideal for continuous use, but they require access to an electrical outlet. Cordless grinders provide greater mobility and convenience, especially for outdoor or remote work, but their battery life may limit usage time. Consider where and how you will be using the grinder to decide which type is more suitable for your needs.
