DEWALT's circular saw lineup covers three blade sizes with different applications. The Atomic 4.5-inch (DCS571B at $99) is the compact format — ultra-light for one-handed use, cuts sheet goods and trim lumber, but can't handle full 2x4 thickness at a bevel. The 6.5-inch (DCS380B at $99 and DCS565B at $138) is the versatile mid-size — adequate for dimensional lumber through 2x4 at 90 degrees, lighter than the full-size 7.25-inch saw. The 7.25-inch (DCS570B at $214.95) matches the traditional full-size circular saw standard used in production framing — maximum cutting depth for 2x6 and structural material. Choose blade size based on the thickest material you'll regularly cut, not the largest material you can imagine cutting.
Brushed vs. Brushless in the DEWALT Lineup
The entry-level 6.5-inch DEWALT at $99 uses a brushed motor; the DCS565B at $138 and DCS570B at $214.95 use brushless motors. Brushless saws maintain consistent blade speed under load — when the blade contacts dense material and slows, the brushless controller responds by increasing current to maintain the target speed. Brushed motors slow more noticeably under load. In practice, the difference is most apparent when ripping thick hardwood or cutting multiple stacked sheets simultaneously. For occasional cuts in softwood framing lumber and plywood, the brushed motor is adequate. For sustained production use or cutting demanding materials, the brushless models deliver meaningfully better consistency and longer motor life.
FLEXVOLT vs. 20V MAX: DEWALT's Two Platforms
The DEWALT 20V MAX circular saws here all use the standard 20V MAX battery platform. DEWALT also makes FLEXVOLT circular saws (60V mode) that use FLEXVOLT batteries, which switch between 20V MAX (in 20V tools) and 60V (in FLEXVOLT tools). FLEXVOLT saws deliver corded-equivalent power from battery for the most demanding cordless cutting applications. The trade-off is FLEXVOLT battery cost — significantly more expensive than 20V MAX batteries. For homeowners and general contractors, 20V MAX circular saws cover the realistic use cases. FLEXVOLT becomes relevant for demolition contractors, production framers, and users who have invested heavily in the FLEXVOLT platform for other high-draw tools like table saws and miter saws.
Left-Blade vs. Right-Blade Orientation
Traditional circular saws (and all DEWALT models here) have the blade on the right side of the motor. Right-handed users cutting with the saw's base plate flat on material see the cut line blocked by the motor housing — they sight along the left edge of the base plate using the notch guide. Some users prefer left-blade orientation (blade on the left) for a clearer sightline. This is a preference issue rather than a performance one. If you're new to circular saws, right-blade orientation is the standard — more instructional content, more compatible jigs, and consistent availability across the lineup. If you have prior experience with left-blade saws and prefer that sightline, verify your model choice before buying.
DEWALT Circular Saw Buying Mistakes
Don't buy a bare tool circular saw without confirming you own the compatible battery — verify that your existing DEWALT 20V MAX batteries fit the specific saw (some compact tools use a different battery form factor). Don't use a circular saw to freehand cut sheet goods larger than 4x4 without a guide rail or straightedge — freehand cuts on plywood sheets wander and the cut quality suffers. A clamped straightedge or circular saw guide costs $15–$40 and transforms sheet good cutting accuracy. Don't set the blade guard in a retracted position before starting the cut — engage the guard and let it retract naturally against the material as you begin the cut.

Read Full Analysis
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.
DeWalt Atomic 20V MAX 4-1/2-Inch Circular Saw DCS571B
“The DeWalt Atomic DCS571B is the right saw for finish carpentry, DIY home projects, and cutting tasks where compact size and one-handed operation matter. Its 4.5-inch blade handles every application t”
See Today’s Price →What we like
- 4.5-inch compact blade and pistol-grip design for one-handed and tight-space cutting
- Lightweight at approximately 3.6 lbs — significantly less fatigue for overhead cuts
- $99 bare tool — half the price of the Milwaukee for buyers with lighter cutting needs
- 20V MAX platform compatibility with DeWalt's broad consumer and professional tool lineup
Watch out for
- 1-9/16-inch cutting depth at 90° limits structural applications — cannot cut double 2x lumber
- 3900 RPM blade speed is lower than the Milwaukee's 5800 RPM
Read Full Analysis
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.
DEWALT DCS570B 20V MAX 7-1/4 In. Brushless Cordless Circular Saw

See Today’s Price →What we like
- Brushless motor extends runtime and tool life
- 7-1/4" blade — same depth as full-size corded saws
- 57° bevel capacity with detents at common angles
- LED work light illuminates cut line
- Compatible with entire 20V MAX battery platform
Watch out for
- Tool-only — battery and charger sold separately
- 6-1/2" blade kerf slightly narrower than some corded models
- No rafter hook
Read Full Analysis
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.
