The 10 Best Cordless Circular Saws

Battery-powered saws ranked from live Amazon data — cut anywhere, no cord.

A cordless circular saw trades a little sustained power for the freedom to cut anywhere — up a ladder, out in the yard, on a job site with no outlet. The catch is the battery: most of the best cordless saws sell as a bare tool (no battery or charger), which is a bargain if you already own that brand's packs and a trap if you don't. Each pick below says whether it's a bare tool or a ready-to-use kit, and which battery platform it rides. Want the most power for the least money? See the corded list.

The best cordless saw money can buy short of a FLEXVOLT. A brushless motor spins a full 7-1/4" blade at 5,500 rpm with an electric brake and a 57° bevel — near-corded performance with no cord. (DEWALT's part number for this listing is DCS590B, the tool-only successor to the older DCS570B.)

A full 7-1/4" brushless cordless saw with an LED worklight and a 56° bevel, on the CRAFTSMAN V20 platform. Priced up from where it sat a year ago, so it's no longer the budget play — buy it for the platform, not the discount.

How we rank

Every tool gets one score from 0 to 100, weighted 50% on its star rating, 35% on how many people have reviewed it (more reviews = more confidence the rating is real), and 15% on the features that matter for the job. The list is ordered by that score. Best Overall is our pick for the best all-around, ready-to-use tool; Best Budget the best value at or under $90; and Money No Object the one to buy if price is no object.

Buyer's guide

Bare tool or kit?

This is the biggest trap in cordless saw listings. A 'bare tool' or 'tool only' saw ships with no battery or charger — a bargain if you already own that brand's packs, useless out of the box if you don't. A 'kit' includes a battery and charger. Every pick above says which it is.

Which battery platform?

A cordless saw is only as good as its batteries. Buying one on the same platform as a drill or driver you already own (DEWALT 20V MAX, Milwaukee M18, RYOBI ONE+, CRAFTSMAN V20) means one battery lineup for everything — a real reason to stay in one brand.

Will cordless keep up with corded?

For most cuts, yes — especially brushless 7-1/4" saws like the DEWALT DCS590. But a corded 15-amp saw still gives more sustained power for the money on long rips and thick stock. If you don't need portability, corded is cheaper and stronger.

What blade size?

6-1/2 inch is the common cordless size — light, with enough depth for 2x lumber in one pass. 7-1/4 inch cordless saws match corded cut depth but drain batteries faster. 4-1/2 inch minis are for plywood, trim, and flooring, not framing.

Watch out for mini saws

Plenty of cheap 'mini' cordless saws in the search results have 4-1/2" or smaller blades and can't cut through a 2x4. They're fine for sheet goods and flooring, but don't buy one expecting a full-size saw — and steer clear of grinders dressed up as saws.

Tools to avoid

Not everything in the search results deserves your money. This one would rank dead last on our scale — here's the listing to walk past, and exactly why.

✕ Avoid

Bigheimer

Bigheimer 4" "Mini Circular Saw" / Cut-Off Tool

3.5 17 reviews $43.99

This isn't a circular saw — it's a 4-inch angle grinder with a saw guard bolted on. It cuts 5/8 of an inch deep and spins at grinder speed. Wrong, and genuinely unsafe, for the work a circular saw does.

Why we'd skip it

It cuts only 5/8 inch (16 mm) deep. A real circular saw cuts about 2-1/2 inches — enough to crosscut a 2x4 in one pass. At 5/8", it can't cut through standard lumber at all.
It's a 4-inch angle grinder with a saw guard, spinning at 12,000 RPM. Real circular saws run around 5,000-5,800 RPM; a wood blade at grinder speed is a kickback and injury risk.
No-name "Bigheimer" brand, sold tool-only (needs a DEWALT battery), and the lowest star rating in the category at 3.5.
If you want to cut metal or tile, buy a grinder. To cut wood, buy a real circular saw.
