Product Information
Full details
The Makita DGA463RTJ is an 18V LXT Cordless Angle Grinder designed for professionals and serious DIYers needing a versatile and powerful cutting and grinding tool. Its key benefit is the combination of a brushless motor for efficiency, variable speed control for precision, and advanced safety features like AFT and electric brake, offering powerful performance with enhanced user protection. A potential caveat is that it operates on 18V LXT batteries, requiring existing Makita battery compatibility or investment in new batteries and a charger.

FAQs
What is the difference between ADT and AFT?
Automatic Torque Drive Technology (ADT) adjusts motor speed and torque based on the load to optimize performance. Active Feedback Sensing Technology (AFT) is a safety feature that shuts down the tool if it detects a sudden slowdown or kickback.
Can I use this grinder for cutting tile?
Yes, with the appropriate diamond cutting blade for tile and by using the variable speed setting to a suitable RPM. Always wear safety glasses and follow best practices for cutting brittle materials.
What is the maximum RPM for this grinder?
The variable speed range is from 3,000 to 10,000 RPM. Ensure your accessories are rated for at least 10,000 RPM.
How long do the 5.0Ah batteries typically last?
Battery life varies significantly based on the task, material, and speed setting used. For typical grinding tasks, a 5.0Ah battery can provide substantial run time, often enough for several hours of intermittent use.
Does this grinder come with batteries and a charger?
Yes, the DGA463RTJ model is a kit that typically includes 2 x BL1850B 5.0Ah 18v batteries, a DC18RC charger, and a Makpac carry case with an inlay.
Can I use this tool in wet conditions?
This is a cordless electric power tool and is not designed for use in wet conditions. Exposure to water can damage the tool and create an electrical hazard.
Troubleshooting
Tool won't turn on
Ensure the battery is fully charged and properly inserted into the tool. Check if the battery latch is engaged. Try a different, known-good battery.
Reduced power or performance
Check the battery charge level. Clean the air vents and dust covers to ensure proper motor cooling and airflow. If the issue persists, the motor may require service.
Grinder stops unexpectedly during use
This could be the AFT engaging due to sudden slowdown or kickback. Release the trigger, check for obstructions, and restart. It could also be an overload protection from the electronic current limiter; reduce pressure or feed rate.
Sparks are excessive
Ensure you are using the correct type of wheel for the material being cut or ground. Excessive sparks can also indicate a worn-out motor brush (though this model has a brushless motor, internal component wear is possible).
