Power and Performance
Delivering 3,700 RPM, the DCS391 is 10 percent more powerful than previous DEWALT 6.5-inch cordless circular saws. This, combined with a new 3.0 Ah lithium-ion battery that provides up to 57 percent more runtime versus leading 18-volt lithium-ion tools, leads to a faster speed of cut and the power needed to make the most demanding cuts with ease.
Its powerful 460 max-watts-out (MWO) motor delivers the power and speed needed to make demanding cuts, and the three speed settings give professionals the option to select the most appropriate speed for a given task. DEWALT-designed electronics have been built into the circular saw’s switch to provide maximum life for the tool and battery by helping to protect them from overheating, overloading, and deep discharge during use.
The included charger has dual voltage capabilities, and it is compatible with both 12-volt max and 20-volt max DEWALT lithium-ion batteries.
