60V max 7-1/4-inch Circular saw with electric brake (tool only - batteries, charger, and 120V adapter sold separately). The dcs575 delivers the power of a corded saw with the portability and convenience of cordless through dewalt's revolutionary flexvolt technology. DEWALT bare tools are a great way to expand your tool box when you already own batteries and chargers. The FLEXVOLT® 20V/60V MAX* Battery pack changes voltage when you change tools, powering a line of powerful 60V MAX* tools, 120V MAX* tools, and backwards compatible to existing 20V MAX* tools and chargers. The battery pack is smart enough to know when to provide runtime for 20V MAX* tools (6.0Ah) and power in 60V MAX* and 120V MAX* tools.
