Verdict

Choose the corded 9564CV if you require constant speed and unlimited runtime for stationary work. Pick the 18V LXT XAG09Z if you need cordless freedom and the option to use larger 5-inch wheels. Both are bare tools, so you must supply your own power source.

Corded Power Versus Cordless Flexibility

Power Source

Edge: Tie

The Makita 9564CV relies on a 13-amp corded motor, providing continuous power without the need for battery management. This setup ensures you never face a dead battery mid-task. In contrast, the Makita XAG09Z operates on an 18V LXT Lithium-Ion system. This cordless design offers significant mobility, allowing you to work in areas without accessible outlets. While the corded model guarantees constant output, the brushless battery tool provides freedom of movement. Your choice depends on whether you prioritize unlimited runtime or the convenience of untethered operation.

Motor Type

Edge: Makita 18V LXT Brushless 4-1/2 / 5-Inch Grinder

The 9564CV features a standard high-power motor designed for robust performance. It includes a mechanical clutch system, Sass technology, which allows the drive shaft to slip if the wheel binds, protecting internal gears. The XAG09Z uses a BL Brushless motor. This design eliminates carbon brushes, reducing friction and heat. Brushless motors run cooler and more efficiently, which can extend the tool's lifespan. The electronic control in the brushless model also optimizes battery energy use, potentially offering up to 50% longer run time per charge compared to brushed equivalents.

Speed Control

Edge: Tie

Both tools offer variable speed capabilities, but they function differently. The 9564CV provides a variable speed dial ranging from 2,800 to 10,500 RPM. It also includes constant speed control, which automatically adds power to maintain speed under load. The XAG09Z utilizes Automatic Speed Change Technology (AST). This system adjusts speed and torque dynamically during operation to maintain optimum performance. While the corded model gives you manual dial control with load compensation, the cordless model uses intelligent automation to adapt to the cutting or grinding task in real time.

Safety Features

Edge: Makita 18V LXT Brushless 4-1/2 / 5-Inch Grinder

The 9564CV employs a mechanical clutch to prevent motor and gear damage if the wheel stops suddenly. It also features a soft start to suppress startup reaction, ensuring smoother operation. The XAG09Z takes a different approach with Active Feedback-Sensing Technology (AFT). This system electronically turns the motor off if rotation is suddenly forced to stop. Additionally, it includes an electric brake that stops the wheel in two seconds or less. The cordless model offers faster wheel stoppage and electronic protection, while the corded version relies on mechanical slip protection.

Weight and Build

Edge: Makita 18V LXT Brushless 4-1/2 / 5-Inch Grinder

The Makita 9564CV weighs 6 pounds and measures 16 inches in length. Its corded design contributes to its overall mass. The XAG09Z is slightly lighter at 5.7 pounds and more compact, measuring 8.39 inches in length. The reduction in weight and size in the cordless model can reduce user fatigue during extended overhead or prolonged use. Both tools maintain a similar width, but the XAG09Z’s shorter body and lower weight make it more maneuverable. The 9564CV’s heavier build may provide more stability for certain heavy-duty applications.
