The Makita DHS680Z is a 165mm (6-1/2) cordless circular saw powered by an 18V Li-ion battery. It features Automatic Speed Control, an electric brake, soft start, and an electronic current limiter for overload protection. The saw also includes a tool hanger, twin LED job lights, a battery fuel gauge, and a rear dust exhaust port. Its design is compact and lightweight with an ergonomic soft grip, a blower function to clear dust from the cutting line, and a larger base for more stable operation. Makita's new Brushless BL Motors offer up to twice the run time of conventional motors and a fast 22-minute charge with the DC18RC charger. These brushless motors draw less amps, generate less heat, and extend battery life, enabling a 3Ah battery to perform like some competitors' 4Ah products. The saw is compatible with the Makita 1.0m Plunge Saw Guide Rail (196953-0), which is ideal for cutting sheet materials and features an extruded aluminum construction with vinyl and rubber seats for smooth operation and secure grip.
