Ranked #6 in Best Circular Saws

Bosch 18V Cordless Circular Saw

3.6

$388as of Jul 1

The Bosch CCS180 18V cordless circular saw offers a lightweight, powerful alternative for professionals and DIYers. Reviewers praised its balance, 4.0Ah battery performance, and anti-snag guard design. The depth gauge and easy handling were highlighted as significant advantages. However, some noted issues with the bevel gauge clarity and occasional depth adjustment rail dislodgement. While not a direct replacement for corded models in heavy-duty framing, it excels in trim work and hard-to-reach areas where portability matters most.

Strengths

— Lightweight and well-balanced at 6.6 pounds, easy to wield one-handed
— Powerful performance with 4.0Ah battery providing extended runtime and cooler operation
— Anti-snag lower guard design prevents guard from snagging on materials

Watch-outs

— Bevel gauge is not clearly marked and lacks arrow indicator for angle identification
— Depth adjustment rail can become dislodged from groove causing sluggish operation
— Trigger safety mechanism is awkward and requires adjustment period for users

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

4.3

$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
