HIGHLIGHTS: The Makita DGA406RF 18V LXT Brushless Cordless 100mm (4") Angle Grinder Set is a professional-grade cutting and grinding tool engineered for high efficiency, safety, and durability on demanding job sites. Powered by Makita’s 18V LXT lithium-ion battery platform and a high-performance brushless motor, this grinder delivers consistent power with extended runtime and reduced maintenance. Designed with Automatic Torque Drive Technology (ADT), the grinder automatically adjusts speed and torque during operation to maintain optimal cutting performance when working under load. This intelligent system ensures smoother operation and maximizes productivity when grinding metal, cutting steel, or preparing surfaces. The grinder also incorporates Makita’s Active Feedback Sensing Technology (AFT), which enhances safety by automatically shutting down the tool if sudden rotation speed reduction is detected, helping to prevent kickback. The built-in electric brake quickly stops the wheel after releasing the trigger, improving user safety and workflow efficiency. Built for harsh environments, the DGA406RF features Extreme Protection Technology (XPT), which improves resistance to dust and moisture for reliable performance on construction sites and fabrication workshops. The slide switch with lock-on function allows comfortable continuous operation for extended grinding tasks. This complete set includes a BL1830B 3.0Ah battery and DC18RC fast charger, providing a ready-to-use cordless grinding solution for professionals requiring portable power, safety, and precision.
