Whether building wood decks or dormers, bookcases or kitchen cabinets, the professional-duty DEWALT DC390B 18-volt, 6-1/2-inch cordless circular saw delivers cordless convenience without sacrificing power or performance. An 18-volt battery (not included) drives the saw's 6-1/2-inch, thin-kerf blade at 3,700 RPM, an optimum speed for crosscutting and ripping construction lumber, softwood, hardwood, plywood, particleboard, oriented-strand board, and virtually any other sheet.

Power and Performance

With depth-of-cut capacities of 2-1/4-inch at 90-degrees and 1-5/8-inch at 45-degree (bevel), the DC390B can slice through all 2-by dimensional lumber. The 6-1/2-inch carbide tipped blade gives you 2x cutting capacity at 90 and 45 degrees, and the 0-50-dgree bevel capacity provides additional capacity for a multitude of applications.

A high strength magnesium shoe and upper guard provides increased durability, while a fan-cooled motor with replaceable brushes provides maximum power and durability. It's complemented by a vibration-dampening rubber-grip handle for comfortable handling on big jobs. This circular saw weighs 6.3 pounds.
