Makita 18V Lithium-Ion Brushless Cordless Cut-Off/Angle Grinder

Stepping into the world of cordless grinders, the Makita XAG09Z offers a compelling mix of power, precision, and convenience. As an avid user of Makita tools, I was eager to see if this grinder lived up to the brand's high standards. After putting it through its paces, I can confidently say it does, and then some.

Design and Build Quality

The first thing that struck me about the Makita XAG09Z is its build quality. True to Makita's reputation, this grinder feels robust and well-engineered. The brushless motor is a standout feature, promising improved efficiency and a longer lifespan. It's clear that Makita has poured a lot of thought into the design, making it a tool that can withstand the rigors of heavy use.

Weighing in at 5.7 pounds (without the battery), the XAG09Z is relatively lightweight for a cordless grinder. This makes it easier to handle during prolonged use, reducing operator fatigue. The overall length of 14-1/4 inches provides a good balance between maneuverability and stability.

Performance

Performance-wise, the XAG09Z does not disappoint. The grinder boasts a no-load speed of 8,500 RPM, which is more than sufficient for most cutting and grinding tasks. Whether you're working on metal, masonry, or wood, this tool handles it all with ease.

One feature that sets this grinder apart is the Automatic Speed Change technology. This smart system adjusts the speed and torque automatically, ensuring optimal performance regardless of the task at hand. I found this particularly useful when switching between different materials, as it allowed for a seamless transition without the need to manually adjust settings.

Safety and Usability

Safety is always a concern when using power tools, and Makita has addressed this with several thoughtful features. The electric brake is a game-changer, stopping the wheel almost instantaneously when the trigger is released. This not only enhances safety but also saves time, as you don't have to wait for the wheel to come to a complete stop before setting the tool down.

The lock-on switch is another welcome addition. It allows for continuous operation without having to keep the trigger depressed, which can be a significant relief during extended use. However, it's worth noting that there is no lock-off switch, so extra caution is advised to prevent accidental activation.

Battery Life and Compatibility

The XAG09Z is compatible with Makita's range of 18V LXT Lithium-Ion batteries. I typically use 4 and 5 amp-hour batteries, and I found that they provided ample runtime for most tasks. The grinder performs well even during consecutive battery changes, ensuring that downtime is kept to a minimum.

One of the advantages of using Makita's LXT system is the interchangeability of batteries across different tools. If you're already invested in Makita's cordless ecosystem, adding the XAG09Z to your toolkit is a no-brainer. It seamlessly integrates with other LXT tools, making it a versatile addition to your collection.

Real-World Applications

In practical use, the XAG09Z excels in a variety of applications. I've used it extensively for metal fabrication, and it has become my go-to tool for grinding and cutting tasks. The power and precision it offers are unmatched, making quick work of even the toughest materials.

One of the standout moments for me was using the grinder for a large-scale project that involved cutting and grinding steel beams. The XAG09Z handled the job with ease, providing consistent performance throughout. The electric brake and lock-on switch proved invaluable, allowing me to work more efficiently and safely.
