The DeWalt DCS391B is a cordless 6-1/2-inch sidewinder circular saw in the 20V MAX line. Its 5150 RPM motor and lightweight magnesium shoe are built for framing, decking and trim work on the jobsite. It cuts 2x material at 90 and 45 degrees, and the 0-50 degree bevel range covers most common angles. It is a bare tool, so it runs on DeWalt 20V MAX batteries you already own. Owners rate it highly for power and balance; the main trade-offs are the modest cut depth of a 6-1/2-inch blade and the need to supply your own battery and charger.

Owners rate the DCS391B 4.8 out of 5 and praise its power, balance and cut quality for a compact cordless saw. Complaints center on it arriving as a bare tool and on the depth limits of the 6-1/2-inch blade.
The DEWALT DCS391B is a 20V MAX cordless circular saw with a 6-1/2 inch blade. Its motor runs at 5150 RPM with no load. It is a bare tool, so the battery is sold separately.
The shoe is made of lightweight, high-strength magnesium for durability on the jobsite and lasting cut accuracy. The grip is rubber over-molded for balance and control. The saw bevels from 0 to 50 degrees, and the carbide-tipped blade cuts 2x material at both 90 and 45 degrees.
