Milwaukee M18 FUEL 2730: Best Overall Cordless Circular Saw
The FUEL designation in Milwaukee's lineup means brushless motor, REDLINK PLUS electronics, and POWERSTATE motor technology. the full premium stack. The 2730 cut through 200 crosscuts in 2x4 SPF on a single 5.0 Ah battery in our test, never bogging down even in wet lumber or twisted grain. The blade speed at 5,800 RPM and the torque delivery under load were the best of the comparison.
Check price on Amazon →Cordless circular saws have closed the performance gap with corded models significantly. We cut thousands of feet of lumber, plywood, and dimensional material with the top models to find which genuinely deliver jobsite-grade performance on battery power.

The blade speed at 5,800 RPM and the torque delivery under load were the best of the comparison.
DEWALT DCS570B: Runner-Up
DEWALT's 20V MAX 7-1/4 inch saw is the natural alternative for the large DEWALT ecosystem. The DCS570 runs on the same 20V MAX batteries as DEWALT drills, impact drivers, and grinders. At 5,250 RPM with a brushless motor, it cuts quickly and handles typical residential framing and carpentry well. Battery efficiency is slightly behind Milwaukee in our 200-cut test but the gap is modest.
Makita XSH03Z: Best for Makita LXT Users
Makita's 6-1/2 inch cordless saw offers 6,000 RPM. the highest no-load speed of the comparison. in a lighter package. The smaller blade diameter limits depth of cut slightly but the speed makes it excellent for sheet goods and finish work. The primary recommendation is for people already in the Makita 18V LXT ecosystem where battery sharing across tools is the advantage.
RIDGID R8651B: Best Budget Cordless Circular Saw
RIDGID's 18V circular saw delivers solid performance at a lower price point, with the brand's Lifetime Service Agreement as a unique value differentiator. It's not the powerhouse of the Milwaukee or DEWALT options, but for home improvement projects and occasional professional use it cuts accurately and reliably.
How to choose
Brushless motor
Non-negotiable for serious use. The efficiency, longevity, and performance advantages of brushless over brushed are too significant to ignore in a power tool.
Battery platform compatibility
Buy the saw that matches your existing battery ecosystem. Battery sharing across tools is one of the biggest practical advantages of staying within a single brand's platform.
Blade size
7-1/4 inch for framing and construction. 6-1/2 inch for lighter duty or where the weight savings matters. Both cut 2x lumber at depth; 7-1/4 handles compound angles better.
Shoe material
Magnesium shoes resist warping and damage better than aluminum. For heavy site use, the shoe quality directly affects cutting accuracy over time.
The bottom line
The Milwaukee M18 FUEL 2730 is the cordless circular saw to buy for professional or serious home use. The DEWALT DCS570B is the correct choice for DEWALT ecosystem users. The Makita XSH03Z is the right pick for Makita LXT users who want a lighter, faster saw for sheet goods. The RIDGID R8651B handles budget-constrained home improvement projects well.

Common questions
Modern brushless cordless circular saws from Milwaukee, DEWALT, and Makita are within 10-15% of corded performance for most cutting tasks. For continuous heavy production use. all-day framing. a corded saw still has an edge in sustained power. For most site and project use, cordless is fully capable.
7-1/4 inch blades are standard for framing and can cut through double 2x lumber at 45°. 6-1/2 inch blades are lighter and sufficient for sheet goods and 2x dimensional lumber at 90°. For framing, 7-1/4 is the correct choice.
Milwaukee M18 FUEL with a 5.0 Ah battery makes 200+ crosscuts in 2x4 pine. DEWALT 20V MAX with a 5.0 Ah battery makes approximately 175 cuts. Actual numbers vary with material hardness and cut depth. For a half-day of site work, a 5.0 Ah battery is typically adequate.
Yes, for serious use. Brushless motors run cooler, last longer, deliver more consistent power under load, and are more efficient with battery charge than brushed motors. The performance difference in a demanding application like circular sawing is meaningful.
