Delivering 3000 SPM from its POWERSTATE Brushless motor, the M18 FUEL SAWZALL reciprocating saw (2821-22) has been re-designed for improved durability and speed to help users make quick work of common cutting tasks. A 1-1/4 in. stroke cuts material faster, while this cordless reciprocating saw's adjustable shoe ensures users get the most life out of their recip blades. REDLINK PLUS Intelligence monitors performance and protects from overload conditions, while the heavy-duty construction ensures this tool will stand up to the job. A new QUIK-LOK chuck with lever-action provides easy keyless blade changes while resisting corrosion. The integrated rafter hook allows users to hang this brushless recip saw when not in use. When paired with M18 REDLITHIUM batteries, this cordless saw has the runtime needed to last through the job.
