Milwaukee Tool has unveiled the second generation M12 FUEL 5-3/8-in. Circular Saw, designed for cross-cutting sheet goods and dimensional lumber.

The POWERSTATE Brushless Motor provides the power required for tough cutting applications, minimizing bog down through large lumber. When paired with a M12 REDLITHIUM HIGH OUTPUT XC5.0 battery pack, the compact circular saw can make up to 190 cuts per charge in 2X4 lumber.  

Milwaukee’s new circular saw delivers portability for cuts in small spaces, overhead and when the capacity of a large saw is not needed. Other features include an LED light for visibility, cut line blower and an integrated hang hook for storage.
