Makita Grinder Comparison Guide
Motor efficiency
Both the Makita XAG04Z-R and the XAG25Z feature brushless motors, which eliminates carbon brushes for cooler running and longer life. The XAG04Z-R explicitly highlights Automatic Speed Change technology that adjusts speed and torque during operation. It also includes Active Feedback Sensing Technology (AFT) to stop the motor if the wheel binds. The XAG25Z data confirms it is brushless but does not list these specific electronic safety or adjustment features in the provided specs. While both use efficient BL motors, the XAG04Z-R offers more detailed electronic protections.
Physical dimensions
The physical footprint of each grinder differs significantly. The XAG04Z-R measures 8.4 inches in length, 4.5 inches in width, and 5.5 inches in height. In contrast, the XAG25Z is listed at 12.7 inches in length, 3 inches in width, and 3.6 inches in height. The XAG25Z is notably longer but narrower and shorter in height. This difference in shape may affect how the tool fits in your hands or on a workbench. You should consider which form factor suits your storage space and handling preferences better.
Weight
Weight impacts how long you can comfortably hold the tool. The XAG25Z data explicitly lists a weight of 1 pound for the tool-only unit. The XAG04Z-R specifications do not provide a weight value in the provided data. Because you have a concrete figure for the XAG25Z, it allows for a direct assessment of its lightness. Without a comparable number for the XAG04Z-R, you cannot definitively say which is lighter. However, the available data gives the XAG25Z the advantage for transparency on weight.
Wheel compatibility
Both grinders are designed to accept 4-1/2 inch and 5 inch wheels. The XAG04Z-R specifies a spindle thread of 5/8 inch - 11 UNC. The XAG25Z data does not list the spindle thread specification. Both tools share the same wheel diameter compatibility, making them interchangeable for standard abrasive disc sizes. If you already own discs for one, they will likely fit the other. The primary difference lies in the mounting thread, which is only confirmed for the XAG04Z-R in the provided data.
Safety features
Safety mechanisms are critical for angle grinders. The XAG04Z-R includes Active Feedback Sensing Technology (AFT) and Automatic Speed Change. AFT turns the motor off if rotation is suddenly forced to stop, reducing kickback risk. The XAG25Z title mentions 'A', likely referring to AFT, but the detailed feature list in the data does not confirm this or list other safety tech. The XAG04Z-R provides explicit documentation of these electronic safeguards, offering you more verified protection details compared to the limited info for the XAG25Z.
Choose the right Makita grinder
Users needing automatic torque adjustment
The XAG04Z-R includes Automatic Speed Change technology. This feature adjusts speed and torque during operation for optimum performance. It also offers Active Feedback-Sensing Technology, which turns the motor off if the wheel stops suddenly. These safety and control specs make it ideal for variable load applications.
Professionals preferring compact and light tools
The XAG25Z weighs only 1 pound and measures 12.7 inches in length. Its compact design reduces fatigue during extended use. This model supports 4-1/2 inch and 5 inch wheels while maintaining a smaller footprint. Choose this if you prioritize portability and reduced weight in your daily workflow.
Buyers wanting 5-inch wheel compatibility
The XAG04Z-R explicitly lists 5-inch wheel diameter compatibility in its key specifications. While both models accept 4-1/2 and 5-inch discs, this model highlights the larger option clearly. Select this tool if you frequently use 5-inch cutting or grinding wheels for broader material removal tasks.

Frequently asked questions
Does the XAG04Z-R come with a battery included?
No, the XAG04Z-R is sold as a bare tool. This means you must already own compatible 18V LXT batteries to operate it. It is designed for users who already have the Makita ecosystem. You will need to purchase batteries and a charger separately to get started with this grinder.
What is the difference in wheel size between the two models?
The XAG04Z-R supports 5-inch wheels, while the XAG25Z is limited to 4-1/2-inch wheels. This makes the XAG04Z-R suitable for heavier cutting and grinding tasks that require larger discs. The XAG25Z is optimized for lighter duties where a smaller wheel diameter is preferred for precision and control.
Which grinder is lighter for overhead work?
The XAG25Z is the lighter option, weighing just 1 pound. Its compact dimensions also make it easier to handle in tight spaces. The XAG04Z-R is slightly bulkier at 8.4 inches long. If you need a tool that reduces arm fatigue during extended overhead use, the XAG25Z is the better choice.
Does the XAG04Z-R have safety features for sudden stops?
Yes, the XAG04Z-R includes Active Feedback-Sensing Technology. This system detects if the wheel stops suddenly and automatically turns off the motor. This helps prevent kickback and potential injury. The XAG25Z does not list this specific safety feature in its data. This makes the XAG04Z-R safer for demanding applications.
Can I use the XAG25Z with a 5-inch disc?
No, the XAG25Z is designed for 4-1/2-inch wheels only. Its specifications list a 4-1/2-inch wheel diameter. You cannot safely or effectively use larger 5-inch discs on this model. If you require the cutting capacity of a 5-inch disc, you must choose the XAG04Z-R instead.
Is the XAG25Z suitable for general household tasks?
Yes, the XAG25Z is ideal for general tasks. Its lightweight design and 4-1/2-inch wheel size make it manageable for home projects. It fits users who want a brushless grinder without the bulk of a larger model. It is a solid choice for light cutting, grinding, and polishing around the house.
