The Best Cordless Miter Saws
A cordless miter saw cuts anywhere—no outlet, no extension cord. You trade a little capacity for real portability. Here are five battery saws ranked, plus honest advice on when corded still wins.
A cordless miter saw earns its place the moment you're cutting somewhere without a convenient outlet—a deck, a roof, a remodel with the power off, or just across the yard. Today's brushless battery saws have closed most of the gap with corded models for trim and framing work. What you're really choosing is a battery platform, a blade size, and how much capacity you need away from the wall.
Be honest about how you'll use it. For a fixed shop where the saw never moves and you cut wide stock all day, a corded 12-inch still gives you more saw for the money. For everyone who values portability, these five are the strongest cordless saws you can buy on Amazon. Product details and ratings were verified against live Amazon listings; picks are research-based, not lab-tested.

What separates a good pick from the rest.
Battery platform
The most important decision. A cordless saw ties you to a battery system, so the smart move is to match the saw to the batteries you already own—DeWalt 20V MAX, Makita 18V LXT, CRAFTSMAN V20 or RYOBI ONE+. Buying into a new platform means buying batteries and a charger too.
Cut capacity
Blade size and slide decide what you can cut. A 6-1/2- or 7-1/4-inch saw handles trim and framing lumber to length; only a 12-inch like the DCS785B matches a corded saw for crown and wide boards. Check the 90-degree and bevel cut specs against the stock you actually cut.
Runtime and motor
Brushless motors run longer per charge and last longer overall—every saw here is brushless. Real runtime still depends on battery size, so pair the saw with a higher-capacity pack (4Ah or more) if you cut all day rather than the small starter batteries.
Weight and portability
The whole point of cordless is mobility. Lighter 6-1/2 and 7-1/4-inch saws are easy to carry up a ladder; the 12-inch trades that for capacity. Think about how often you'll lift and reposition it before chasing the biggest blade.
Tool-only vs kit value
Most cordless saws sell as a bare tool, so the sticker price isn't the real price once you add a battery and charger. A complete kit like the CRAFTSMAN can be cheaper all-in than a 'cheaper' bare tool you have to feed with batteries.
Frequently asked questions
Who makes the best cordless miter saw?
It depends on your battery platform. DeWalt's 20V MAX saws (the DCS361 and 12-inch DCS785) are the best-rounded and most widely owned on Amazon. Makita's 18V LXT saws are prized for compact precision. CRAFTSMAN and RYOBI cover value and DIY. The best one for you is usually whichever matches batteries you already have—the saw itself matters less than the ecosystem.
Is a cordless miter saw worth it?
If you ever cut away from an outlet, yes. Cordless saws let you work on a deck, a roof, or a powered-down remodel with no cord to trip over or run, and modern brushless models have plenty of power for trim and framing. For a stationary shop where the saw never moves and you cut wide stock all day, a corded saw still gives more capacity for the money.
Are cordless miter saws as powerful as corded?
For most cuts, modern brushless cordless saws are close enough that you won't notice—they crosscut framing lumber and trim cleanly. The gap shows up in sustained heavy use and in capacity: the biggest cordless 12-inch saws match corded ones, but smaller 7-1/4-inch models cut less in a pass. For all-day production cutting of wide hardwood, corded still has the edge.
Do cordless miter saws come with a battery?
Usually not. Most cordless miter saws are sold as a 'bare tool,' meaning the battery and charger cost extra—important when you compare prices. A few ship as a complete kit: the CRAFTSMAN CMCS714M1, for example, includes a V20 battery and charger, so its price is the all-in price. Always check whether a listing is tool-only or a kit.
Is a Milwaukee or DeWalt cordless miter saw better?
Both make excellent cordless saws—Milwaukee's M18 FUEL sliders are jobsite favorites. The practical catch is availability: Milwaukee restricts third-party Amazon sales, so if you're buying on Amazon, DeWalt's 20V MAX saws are the easiest premium option to actually get. If you already run M18 batteries and can buy locally, Milwaukee is well worth considering too.
