Full details
The Makita DGA517RTJ is an 18V LXT Brushless 125mm Angle Grinder designed for professionals and serious DIYers tackling metal fabrication, construction, and renovation tasks. Its key benefit is the combination of a powerful brushless motor, variable speed control, and advanced safety features like AFT and a paddle switch, offering efficient and safe operation.

FAQs
What is the benefit of a brushless motor in this grinder?
A brushless motor provides more power, longer run times, increased durability, and a more compact tool design compared to brushed motors.
How does the Active Feedback Sensing Technology (AFT) work?
AFT monitors the tool's performance and will shut down the motor instantly if it detects a sudden slowdown or 'kickback' caused by the accessory binding, protecting the user.
Can I use this grinder for extended periods without interruption?
Yes, the inclusion of two 5.0Ah batteries allows for continuous operation by swapping batteries when one runs low. The ergonomic design also helps reduce fatigue.
What types of accessories can I use with the DGA517RTJ?
You can use standard 125mm grinding wheels, cutting discs, flap discs, and wire cup brushes, provided they are rated for the tool's maximum RPM and suitable for angle grinders. Always use the correct guard for the accessory.
Is this grinder suitable for wet applications?
The tool features XPT (Xtreme Protect Technology) which offers enhanced protection against dust and water splashes, making it more resilient in damp conditions, but it is not designed for submersion or heavy water exposure.
How do I adjust the speed?
The speed can be adjusted using the variable speed control dial located on the tool body. It's recommended to consult the user manual for specific speed settings for different applications.
Troubleshooting
Tool does not turn on.
Ensure the battery is fully charged and correctly inserted. Check if the safety paddle switch is being engaged properly. Verify that the battery is compatible with the Makita 18V LXT system.
Reduced performance or motor stops under load.
Check the battery charge level. Ensure the accessory is not binding or dull. Clean any dust buildup from the motor vents and check for obstructions. The AFT may be engaging if the tool is severely overloaded or the accessory binds.
Excessive vibration.
Ensure the accessory is correctly mounted and balanced. Check for damage to the accessory. Verify that the guard and side handle are securely attached.
Tool overheats.
Reduce the workload or duration of use. Ensure motor vents are clear of debris. Use the appropriate speed setting for the task; high speed on soft materials can cause overheating.
