The Milwaukee M18 FUEL SAWZALL reciprocating saw 2 battery kit is the next generation of legendary performance and durability, designed for the toughest jobsite applications. The M18 FUEL SAWZALL is the fastest cutting reciprocating saw in its class and leverages a POWERSTATE brushless motor to provide 3000 spm and a 1-1/4 in stroke length for faster material removal. REDLINK PLUS electronics ensure maximum performance under stress in addition to protection from overloading, overheating and over-discharging. This M18 FUEL SAWZALL is designed to perform in the most demanding applications and is our most durable cordless reciprocating saw yet. A wear-resistant blade change, anti-corrosion blade clamp and metal reinforced battery rails provide longer component life and stand up to the toughest jobsite conditions. The M18 FUEL SAWZALL reciprocating saw weighs less than the previous generation and features an adjustable shoe, integrated LED light and a hanging hook for convenient storage on the job. Compatible with ONE-KEY, this reciprocating saw wirelessly connects to a smartphone to customize, track and manage the tool's performance and location. Tool customization allows for connecting and controlling settings such as output speed and trigger ramp up for smoother cut starts. A selectable cut brake feature automatically stops the blade from reciprocating at the end of a cut, reducing the risk of damaging sensitive materials near the cut in most applications.
