The Makita XAG04Z is a cordless angle grinder that stands out with its combination of an 18V lithium-ion battery and a brushless motor, offering efficiency and longevity. One of its notable features is the Automatic Speed Change technology, which automatically adjusts speed and torque during use, ensuring optimal performance. The Active Feedback-sensing Technology (AFT) is a significant safety feature that shuts off the motor if the wheel is forced to stop suddenly, adding an extra layer of user protection.

The brushless motor design not only reduces maintenance but also enhances the tool’s efficiency and runtime, making it a reliable choice for longer projects. With a no-load speed of 8,500 RPM and the flexibility to use either 4-1/2” or 5” discs, it is versatile for various cutting and grinding tasks. Weighing 4.8 pounds, it strikes a good balance between sturdiness and manageability, though some users might find it slightly heavy for prolonged use.

The ergonomic design and included components like different wheel guards and wrenches add to its convenience. However, it’s worth noting that the package does not include the battery, which needs to be purchased separately. This grinder has received favorable reviews, averaging 4.7 out of 5 stars from 2,856 ratings, indicating high user satisfaction. It is particularly suitable for those looking for a robust, efficient, and safe tool for both professional and DIY tasks.

One of its strongest features is the safety mechanisms, including a quick-stop brake that halts the wheel within 2 seconds, and a Kickback Brake that activates during pinch or bind-up events to prevent accidents. These features, along with the Power Loss Reset, significantly enhance user safety.

In terms of ergonomics, its compact design (12.9 inches in length) and moderate weight make it relatively comfortable to handle, though prolonged use might still cause some fatigue. However, the lack of included battery and charger could be a downside for those who don’t already own compatible DEWALT tools. The tool-only nature means extra purchases are necessary to get started. Ideal for DIY enthusiasts and professionals who prioritize safety and ease of use, but be prepared for additional investment in batteries and chargers if needed.

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.
