Best Cordless Circular Saw Reviews for 2020

Cordless has come a long way since the early days of lithium-ion power. Where circular saws were initially struggling for adequate performance (and even a 7-1/4-inch blade), they now exceed the performance of 15-amp corded models. We decided to test the waters and pulled our expert team together to discover who makes the best cordless circular saw from an elite top tier of advanced models.

Even though we’re East Coasters, we decided to open things up a bit here at the top tier. We have both sidewinder and rear-handle styles in this test and we’ll give you our opinion on both.
Best Cordless Circular Saw Overall
Best Sidewinder: Metabo HPT MultiVolt Circular Saw C3607DAWhen the final scores were tallied, Metabo HPT’s MultiVolt circular saw-edged out the Milwaukee M18 Fuel. Thanks to perfect scores in the cutting performance and accuracy sections and high scores in most of the others, it comes away with our award for the Best Cordless Circular Saw.

The one thing our testing team really didn’t like about Metabo HPT’s design was how close the handles are to each other. If you’re in the same boat, Milwaukee’s M18 Fuel 2732 finished in a close second place.

Best Rear-Handle: Milwaukee M18 Fuel Rear-Handle Circular Saw 2830All four of the rear-handle saws in our testing scored more than 90 points overall and Milwaukee’s M18 Fuel Rear-Handle Saw managed to earn a little bit of separation as our best cordless circular saw in the rear-handle division.

With perfect scores in our accuracy and movement sections to go along with a near-perfect score in cutting performance, it overcomes higher weight and so-so handle design to take the win.

Best Cordless Circular Saw Cutting Power
Best Sidewinder: Metabo HPT MultiVolt Circular Saw C3607DABest Cordless Circular Saw – Metabo HPT MultiVolt
As we ran through a ton of tough cuts that included a stall test, the Metabo HPT MultiVolt circular saw proved it could keep its blade turning with more power than any of its peers. It’s so strong that it may benefit from a diamond arbor to keep the blade from slipping in extreme situations.
The Skilsaw TrueHVL 48 Worm Drive is the only true worm drive in the rear-handle group and its cutting performance showed. As we cut, its worm drive gearing consistently applied more torque to the toughest cuts than its competitors.

Best Cordless Circular Saw Capacity
Best Sidewinder: Makita 18V X2 LXT 9 1/4-Inch Circular Saw XSH10The Makita XSH10 has the biggest capacity of any cordless circular saw we’ve tested. Its 9 1/4-inch blade is capable of cutting 3x material in a single pass – something important if your local code allows for 3x engineered lumber.

If you want to stick with a 7 1/4-inch blade, the Ridgid Octane cuts deeper than its competition at 2 11/16 inches.

3x dimensional lumber is 2 1/2 inches thick, meaning DeWalt (2 9/16-inch) can also cut it. Milwaukee and Kobalt (2 1/2 inches) are right on the edge.

Best Rear-Handle: Makita 18V X2 LXT Rear-Ha.
