The M18 FUEL 7-1/4 in. Circular Saw (model 2371) cuts faster and weighs as much as 40% lower than corded saws without sacrificing cut depth or performance, at the same time as delivering twice the run time of other 18-Volt cordless circular saws. Utilizing a POWERSTATE Brushless Motor, it also cuts faster than corded counterparts. Weighing in at only 9 lbs. with the battery pack (sold one after the other), it features REDLINK PLUS Intelligence, an advanced system of cordless power tool electronics that provides optimized performance and overload protection by the use of total system communication between tool, battery and charger. This circular saw is designed with an LED light to extend accuracy in low-light situations and a rafter hook for simple storage in between cuts. Additionally it is a magnesium shoe in addition to upper and lower guards to scale back tool weight without sacrificing durability.
