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 light, battery fuel gauge, and a rear dust exhaust port. Its compact and lightweight design with an ergonomic soft grip makes it comfortable to use. A blower function clears wood dust from the cutting line, and the larger base provides more stable operation. Makita's new Brushless BL Motors offer up to twice the run time of conventional motors and a quick 22-minute charge with the DC18RC charger. Brushless motors draw less current, generate less heat, and extend battery life. This saw is also compatible with the BAP 1.5M Aluminium Guide Rail, which is 1500mm long, made of extruded aluminum, and ideal for cutting sheet materials. The guide rail has a vinyl seat for smooth machine sliding and rubber seats for grip, along with rubber splinter guards. The vinyl and rubber seats are peel/stick for easy replacement.
