The DEWALT 20V MAX Circular Saw (DCS391B) is a cordless sidewinder built for the cuts you would otherwise drag a corded saw and an extension cord across the jobsite to make. Its 5,150 RPM motor drives the included 6-1/2 inch, 18-tooth carbide-tipped blade through framing lumber and sheet goods, reaching 2-1/8 inches of depth at 90 degrees and 1-5/8 inches at 45 degrees, so 2x material clears in a single pass. The high-strength magnesium shoe keeps the saw light without giving up the rigidity that holds a cut line straight over a long day, and the bevel adjusts anywhere from 0 to 50 degrees…
