Our take on the DEWALT 20V MAX Circular Saw, Cordless Sidewinder Style Portable, 6-1/2-Inch Blade

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.

What reviewers say

  • 4.8 / 524 ratings

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.

What people mention
  • PowerPraisedOwners say the 5150 RPM motor cuts through framing lumber without bogging down.
  • WeightPraisedThe magnesium shoe and compact body make it easy to handle overhead and one-handed.
  • Bevel cutsPraisedReviewers report accurate results across the 0-50 degree bevel range.
  • BatteryCriticisedBuyers note it ships without a battery or charger, so the cost of the platform counts.
  • Cut depthMixedThe 6-1/2-inch blade handles 2x material at 90 and 45 degrees but limits cuts in thicker stock.

About the DEWALT 20V MAX Circular Saw, Cordless Sidewinder Style Portable, 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.

Questions and answers

Does the DCS391B come with a battery?
No. It is a bare tool and includes only the saw and a 6-1/2-inch carbide-tipped blade. You need a DeWalt 20V MAX battery and charger.
How deep will it cut?
It cuts 2-1/8 inches deep at 90 degrees and 1-5/8 inches at 45 degrees. That covers 2x lumber at both angles.
What blade does it use?
It takes a 6-1/2-inch blade with a 5/8-inch arbor. A carbide-tipped blade is included.
Can it make bevel cuts?
Yes. The shoe bevels from 0 to 50 degrees for angled cuts.
Is it worth it over a corded saw?
If you already own DeWalt 20V MAX batteries, it gives cordless freedom with comparable power for most jobsite cuts. A corded saw makes sense if you rarely need portability.

Framers, remodelers and DIYers on the DeWalt 20V MAX platform who want a light, compact saw for 2x material and trim.
