DEWALT ATOMIC 20V MAX 4-1/2-Inch Circular Saw (DCS571B)
1 source$129as of Aug 1

The DeWalt Atomic 20V Max Circular Saw (DCS571B) is compact and light, built for tight spaces and smaller projects. Pro Tool Reviews praised how easily it cuts one-handed and how well it fits punch list jobs around the house. An inline design and brushless motor spin at 4500 RPM, though the 4-1/4-inch blade means lower tip speed. It works as a supplement to a traditional saw rather than a replacement, so buyers who want portability over raw cutting capacity should look here. Homeowners and pros handling thinner materials in confined areas are the fit.

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 6-1/2 inch Cordless Circular Saw

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 4-1/2-Inch Circular Saw (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.
