Power tools for trade use that promise reliable grinding performance, aimed at professionals who need consistent results on site. Confident handling and safety features help reduce fatigue and keep jobs running smoothly. Is the Makita DGA504Z Angle Grinder the right cordless grinder for demanding workshop and site work?
⚡ At a Glance
- • Cutting Power: Brushless 18V Li-ion LXT motor delivers sustained torque for heavy-duty grinding and cutting
- • Best for: Tradespeople and experienced DIYers tackling metalwork, masonry and regular site grinding
- • Not ideal for: Users who need a corded, continuous-power setup for uninterrupted, long-duration industrial use
Cordless 18V LXT brushless power matched to a 125mm wheel makes the tool suitable for heavy-duty grinding. Built-in safety and motor control systems maintain consistent performance under load.
Consistent power and longer runtime – thanks to brushless 18V Li-ion LXT motor
Brushless motor design reduces mechanical losses and improves electrical efficiency, allowing the motor to sustain torque for longer periods. The LXT 18V platform is specified in the product name and aligns with Makita's cordless system.
Sustained power under load helps keep momentum on demanding cuts, while improved runtime reduces battery swaps during extended tasks.
Controlled cutting behaviour – with Automatic Torque Drive Technology and automatic speed control
Automatic Torque Drive Technology adjusts motor torque according to load, while automatic speed control monitors RPM to keep performance steady during variable resistance. Electronic current limiter protects the motor under heavy strain.
Steadier wheel speed produces smoother finishes and fewer snags when cutting or grinding tougher materials, making results more predictable on-site.
Safer, more comfortable operation – thanks to slide switch with lock-on, anti-restart and spindle lock
Slide type switch includes a lock-on function for continuous operation and an anti-restart circuit prevents accidental start after a power interruption. Spindle lock simplifies wheel changes.
Reduced operator fatigue on long runs and quicker maintenance between jobs, with safety measures that lower the chance of accidental starts.
