Product Overview
The DEWALT 20V MAX Circular Saw (DCS391B) is a bare cordless circular saw listed at 6 1/2 inches, with a 5150 RPM motor and a magnesium shoe. It is sold without a battery or charger, so it is aimed at users who already own DEWALT 20V MAX batteries.
This review checks the saw's listed features, including motor speed, shoe construction, grip comfort, and bevel range. It also looks at what the listing does and does not confirm, such as weight and box contents.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
5150 RPM motor delivers power and speed for demanding cuts.
High strength and lightweight magnesium shoe provides jobsite durability for long-term cut accuracy.
Optimized rubber overmolded comfort grip delivers optimal balance and control.
0 to 50 degree bevel capacity allows aggressive bevel cuts for a multitude of applications.
Runs on DEWALT 20V MAX batteries; battery is not included.
Design and Build Quality
The saw uses a high strength and lightweight magnesium shoe, which DEWALT says provides jobsite durability and long-term cut accuracy. The body is yellow and the grip is rubber overmolded for balance and control.
The listing does not confirm the tool's weight or dimensions, so handling feel cannot be judged from the specs alone. A 6 1/2 inch size is typical for compact cordless saws, but no blade or wrench is listed as included.
Performance in Everyday Use
With a 5150 RPM motor, this saw is built for fast cuts in demanding applications. The 0 to 50 degree bevel range covers common bevel cuts, and the cordless design allows use away from outlets when paired with a charged 20V MAX battery.
A real limitation is that no battery or charger is included, so out of the box the saw cannot run unless you already have compatible DEWALT 20V MAX batteries. Also, the listing does not confirm maximum cut depth at 90 or 45 degrees, which are important for purchase decisions.

Alternatives Worth a Look
