We compared five current bare-tool cordless circular saws across five separate battery platforms, checking manufacturer specs against independent test data on cut depth and RPM under load.
Among these five, the DeWalt DCS578B FLEXVOLT stands out for raw output: DeWalt rates it at roughly 47% more power than its prior-generation 60V saw, though it requires a FLEXVOLT-specific battery rather than a standard 20V MAX pack, a real added cost most buyers don't anticipate. The Makita GSH01Z is the pick for anyone who wants weather sealing and the widest bevel range (56°) but is starting a battery platform from scratch, since Makita's 40V XGT system doesn't share batteries with its older 18V LXT lineup. Budget-focused buyers land on the SKIL CR5440B-00, which pairs a low price with an unusually long 5-year warranty. The Metabo HPT C3607DBQ4 suits anyone already on that brand's MultiVolt platform who wants a torque-adaptive motor, and the RIDGID R8657B is the cheapest entry point for buyers who already own RIDGID 18V batteries, even non-OCTANE ones. Every saw here ships as a bare tool with no battery or charger included, which is easy to miss when comparing sticker prices.

Buyer checklist
We pulled specifications directly from each manufacturer's product page (DeWalt, Makita, SKIL, Metabo HPT, and RIDGID), then cross-checked cut-depth, RPM, and weight figures against independent published testing and retailer listings for packaging and pricing details. We did not run our own hands-on testing; where manufacturer and third-party figures disagreed, we flagged the discrepancy rather than picking one silently.
Not necessarily. All five saws in this comparison use a 7-1/4" blade rather than the smaller 6-1/2" size found on compact cordless saws, but their actual 90° cut depths still range from about 2-7/16" to 2-9/16" because shoe and guard geometry, not just blade diameter, set the real-world limit. A 6-1/2" compact saw is usually lighter and one-handed friendly but tops out around 2-1/8" of cut depth, which matters more for framing 2x material than the blade size alone.
A sidewinder (also called a direct-drive saw) mounts its motor beside the blade and spins it directly, which is why all five saws in this guide, being sidewinder-style, hit no-load speeds in the 5,000-6,000 RPM range. A worm-drive saw mounts the motor behind the blade at a right angle through a gear set, which trades top speed (often around 4,250 RPM) for more torque and better performance in thick or wet lumber. Cordless worm-drive saws exist but are far less common than cordless sidewinders, which is the style every product on this page uses.
No. DeWalt's 60V FLEXVOLT DCS578B does carry the highest rated output of this group, but motor design, blade brake, and control electronics (like Metabo HPT's Torque Boost mode) affect real cutting performance as much as raw battery voltage. Treat voltage as one input, not a substitute for checking a saw's actual rated cut depth, RPM, and independent test results.
