Makita 100mm Cordless Angle Battery and Charger Sold GA052GZ Gryller, 40Vmax, Separately,

World's fastest cutting speed. Even more powerful under heavy load when used with a high-output battery.*When a high-output battery is installed. Among rechargeable disc grinders. As of April 2023, according to Makita research. Cutting efficiency increased by approximately 30%.*When BL4040F is installed. Compared to conventional Makita models (when BL4040 is installed). Unleash overwhelming power. Perform tasks with even greater tenacity under heavy load. BL4040F/BL4050F: 2.1kW class, BL4080F: 2.8kW class. Reduced recoil from kickback. Detects and stops sudden drops in rotational speed caused by kickback. *Note: This function does not prevent kickback itself. High-rigidity cylindrical motor housing and vibration-damping rubber. Improved durability and reduced vibration associated with high rotation speeds. Waterproof protection rating IPX6. *Products with an IP rating are designed to be resistant to dust and water, but this does not guarantee that they will not malfunction. When a battery is installed, the protection rating of the main unit applies. DC 36V (40Vmax), slide-type Li-ion battery specification. Battery and charger sold separately.
