Ranked #3 in Best Circular Saws
DEWALT ATOMIC 20V MAX* Circular Saw, 4-1/2-Inch, Tool Only (DCS571B)
$169as of Jul 1

The DeWalt Atomic 20V Max Circular Saw (DCS571B) is a compact, lightweight alternative designed for tight spaces and smaller projects. Pro Tool Reviews praised its ease of one-handed cutting and suitability for punch list jobs around the house. The saw's inline design and brushless motor deliver 4500 RPM, though its 4-1/4-inch blade results in lower tip speed. While it excels as a supplement to traditional saws rather than a replacement, it's recommended for users seeking portability over raw cutting capacity. It's best suited for homeowners and pros handling thinner materials in confined areas.

Strengths
  • — Lightweight and compact design allows cutting in spaces traditional circular saws won't fit
  • — Brushless motor provides efficient power with 4500 RPM spindle speed
  • — Removable auxiliary handle offers increased control and maneuverability
Watch-outs
  • — Blade tip speed is reduced due to smaller 4-1/2-inch blade compared to standard 7-1/4-inch saws
  • — Height and bevel adjustment markings are difficult to read

How they stack up

DEWALT 20V MAX Circular Saw, Cordless Sidewinder Style Portable, 6-1/2-Inch Blad

The DEWALT 20V MAX saw outperforms the DeWalt 20V Cordless and Atomic models in terms of power and blade size, but lacks the lightweight design and built-in LED light found in the latter two. Unlike the SKIL 5280-01, it doesn't include a laser guide, but offers a more powerful motor and carbide-tipped blade for demanding cuts.

DEWALT ATOMIC 20V MAX* Circular Saw, 4-1/2-Inch, Tool Only (DCS571B)

The DeWalt Atomic 20V MAX saw is more compact than the DEWALT 20V Cordless and DEWALT 20V MAX models, but it has a smaller blade that reduces tip speed. Unlike the Bosch 18V model, it lacks a built-in LED light, and compared to the DeWalt DWE575, it lacks the 57-degree bevel capacity and aluminum shoe.
