Key Features & Benefits
- 40V MAX XGT Platform — 40% Faster Cutting — The higher voltage platform delivers substantially more power than 18V equivalents, resulting in faster material removal and reduced strain on the disc through thick sections.
- Active Feedback-sensing Technology (AFT) — Automatically stops the disc when kickback is detected, protecting the operator from sudden uncontrolled rotation — essential on a high-power machine.
- Upsized Ball Bearings — Larger bearings engineered to handle the higher rotor forces generated by the 40V motor, extending service life under heavy use.
- Advanced Heat and Dust Protection — Sealed construction designed for the higher thermal loads of the 40V platform, maintaining reliability in sustained grinding applications.
- Electric Brake — Stops the disc rapidly after releasing the trigger, reducing wait time between operations and improving site safety.
- Soft Start — Gradual acceleration to running speed eliminates startup shock on both the disc and the operator’s wrist.
- Anti-Restart Protection — Prevents the tool restarting after a power interruption, avoiding unexpected start-ups when power is restored.
When to Use This Grinder
The GA005GZ is the choice when 18V cordless grinders are not keeping up with the workload — heavy structural steel fabrication, sustained cutting through thick sections, or applications where battery run time on 18V is not adequate. The 40V XGT platform is Makita’s highest-performance cordless battery range. Note: this tool requires 40V MAX XGT batteries, which are not interchangeable with Makita 18V LXT batteries. If you are starting fresh on a new battery platform, the 40V XGT investment is justified by the significant step up in cutting and grinding performance.
