Best Cordless Circular Saws 2026 — Brushless 18V and 20V Models Tested

DEWALT DCS565P1 cordless 6-1/2" circular saw at $179 — 20V MAX brushless motor delivers 5,150 RPM with electric brake for safety and productivity. Blade-left design improves sightline for right-handed users during rip cuts. 57° bevel handles compound angles. The 20V MAX ecosystem covers 600+ tools, making this an easy ecosystem addition. Compared to Milwaukee M18 ($149), DEWALT costs $30 more with slightly higher RPM and blade-left design; the Milwaukee edges on motor reputation. Compared to Makita X2 ($249), the 6-1/2" blade limits depth vs. 7-1/4" for thick framing lumber. Best for DEWALT 20V MAX users or buyers starting a professional-grade cordless tool collection.

Milwaukee M18 cordless 6-1/2" at $149 — the value leader among professional-grade saws. 5,000 RPM POWERSTATE brushless motor is known for sustained power through demanding cuts without fade. REDLINK PLUS intelligence prevents overloads that damage tool and battery. Equivalent 2-1/8" cutting depth and 56° bevel to DEWALT at $30 less. Compared to DEWALT ($179), Milwaukee's motor reputation in demanding conditions is a genuine differentiator for professionals. Compared to RYOBI ($99), the $50 premium delivers measurably better performance in hard cuts through engineered lumber and hardwoods. Best for professional contractors and Milwaukee M18 platform users wanting proven performance at a competitive price.

Makita XSH06Z dual-battery X2 7-1/4" circular saw at $249 — two 18V LXT batteries combine for effective 36V power driving a full 7-1/4" blade to 2-9/16" cutting depth, matching corded saws for full-depth rafter, joist, and 4×4 post cutting. Compared to DEWALT 6-1/2" ($179), the extra $70 buys the larger blade and depth needed for thick framing lumber. Compared to BOSCH PROFACTOR ($199) also 7-1/4", Makita requires managing 2 batteries vs. one — more complex setup but more balanced weight distribution. Best for Makita LXT users who need full-depth cutting equivalent to a corded worm drive on heavy framing projects.

BOSCH GKS18V-25GN PROFACTOR at $199 — single 18V battery 7-1/4" saw with BITURBO brushless motor running at 5,800 RPM (highest no-load speed on this page) and maintaining speed through thick stock where competitors slow noticeably. 56.5° bevel. Single-battery design is simpler than Makita's dual-battery setup. Compared to Makita X2 ($249), costs $50 less with same blade size and a faster motor; the PROFACTOR platform's caveat is that 12Ah or 8Ah batteries are recommended for peak performance (small batteries underperform). Compared to DEWALT 6-1/2" ($179), costs $20 more for the 7-1/4" blade and deeper cuts. Best for carpenters who want 7-1/4" capability without managing two batteries.

RYOBI ONE+ HP PCL540B brushless compact saw at $99 — the lowest-cost entry to cordless circular sawing. 18V ONE+ platform covers 300+ tools at the highest ecosystem volume in the consumer market. Brushless motor delivers respectable 4,700 RPM; may slow in thick hardwoods or engineered lumber under load. Compared to Milwaukee ($149), the $50 savings is real but tangible power gap emerges in demanding cuts. Compared to DEWALT ($179), saves $80 — smart for DIYers who need occasional framing or deck work. 2-1/8" cutting depth handles standard framing. Best for homeowners, weekend DIYers, and new tool buyers who want cordless sawing capability at the lowest cost and can accept some compromise in heavy-cut performance.
