Best DeWalt Circular Saws of 2026: 20V & Flexvolt

The DeWalt 6-1/2-Inch 20V MAX Circular Saw is the entry point in the DeWalt cordless circular saw lineup — the most affordable way to get a DeWalt circular saw into the 20V MAX ecosystem. At $99 and 7.0 lbs, it is one of the lighter saws on this page, and the 6-1/2-inch blade handles ripping 2x4 framing lumber, crosscutting plywood and OSB, and general rough carpentry tasks that represent the majority of homeowner and remodeling work. Compatibility with all DeWalt 20V MAX batteries means buyers already running DeWalt drills, impact drivers, or reciprocating saws can add this saw without a new battery investment. The brushed motor is the honest trade-off for the lower price. Compared to the DCS565B brushless and the 7-1/4-inch DCS570B further up on this page, the brushed design runs less efficiently per amp-hour, generates more heat on extended cuts, and carries a shorter service life before motor wear requires attention. The lack of an electric brake means the blade coasts to a stop after the trigger releases — slower than the instant-stop of brake-equipped saws — which adds a few seconds of wait time between cuts. For a homeowner who builds a deck or finishes a basement once every few years and already owns 20V MAX batteries, the $99 entry price is the right starting point. For a contractor making hundreds of rip cuts per day, the brushless DCS570B is the appropriate tool.

The DCS565B at 7.2 lbs is the lightest brushless circular saw in the DeWalt 20V MAX lineup — relevant for repeated cuts through a full sheet of plywood where arm fatigue accumulates over a work session. The brushless motor extends battery runtime versus brushed alternatives, reducing interruptions for battery swaps on larger projects. The 50° bevel capacity handles standard compound angle cuts for crown molding and trim work. At $138.00 it is $76 less than the DCS570B 7-1/4" at $214.95. The tradeoff is blade size: the 6-1/2" blade reduces maximum cut depth versus a full 7-1/4" saw, which matters for thicker structural stock but not for sheet goods, dimensional lumber under 2 inches, and most residential renovation and trim cutting applications.

The DeWalt Atomic DCS571B's 4.5" blade and pistol-grip design at approximately 3.6 lbs enables one-handed operation for overhead cuts and tight-access work where a standard 7-lb circular saw is impractical. Finish carpenters and trim workers regularly cut in positions requiring one hand on the saw while the other steadies the material; the Atomic addresses exactly that use case with a design purpose-built for it. At $179.00 it costs $41 more than the DCS565B 6-1/2" model but is substantially lighter. The tradeoff is cut depth: the Atomic's 1-9/16" cutting depth at 90° handles trim work, sheet goods, and standard dimensional lumber up to 1.5" but cannot cut through double 2x lumber or thicker structural stock. For households focused on finish carpentry, renovation trim work, and general home projects that do not involve structural framing, the Atomic provides more practical handling than the larger DCS565B or DCS570B.

The DEWALT DCS570B provides the same 7-1/4" blade diameter as full-size corded circular saws in a cordless 20V MAX package — the specification that determines maximum cut depth and compatibility with the full range of standard carbide blade selection. The 2-9/16" cut depth at 90° handles double 2x framing lumber that the DCS565B 6-1/2" and DCS571B Atomic cannot cut in a single pass, making it the correct saw for deck building, structural framing, and any application requiring full-depth cuts through dimensional lumber. The brushless motor extends runtime per battery charge, with the 57° bevel capacity and angle detents at common positions enabling compound cuts without manual angle measurement. The LED work light illuminates the cut line in shadow conditions common in construction and shop environments. At $214.95 it costs $76 more than the DCS565B 6-1/2" at $138.00 and $35 more than the Atomic DCS571B at $179.00. The premium over the DCS565B buys the 7-1/4" blade — full framing cut depth. For homeowners in the DeWalt 20V MAX ecosystem who do any structural framing, deck construction, or work requiring maximum saw depth, the DCS570B is the correctly specified tool. The DCS565B is the better choice for sheet goods and trim work where 6-1/2" capacity is sufficient and lower weight reduces fatigue over a full day of cutting.
