Best Circular Saw Blades of 2026

Crosscut a sheet of plywood with the blade that came in the box and you get a fuzzy edge that needs a sanding block. Swap in this 40-tooth Diablo and the same saw leaves an edge you can install. That swap is the entire argument for owning a second blade, and it's why this is the one we recommend first to anyone with a 7-1/4-inch saw.

Forty teeth in an alternate-top-bevel grind slice wood fibers instead of tearing them, which is the difference you see on veneered plywood, melamine, and trim. The plate is thin at 0.09 inch, and we appreciate that on a saw already working hard in thick stock: less steel in the kerf means less drag on the motor and a faster feed. The Perma-Shield coating is a small thing that becomes a bigger one over a season, because pitch and sap wipe off instead of baking on, and a clean blade runs cooler.

Fit is where a lot of blade purchases go wrong, and this one covers the common setups: a 5/8-inch arbor with a diamond knockout, so it seats on saws with a round arbor shoulder and on the diamond-shaped ones. It's rated to 8,000 RPM, which you should check against the no-load speed printed on your saw before mounting anything.

What it won't do is demolition. Forty teeth in lumber full of nails or wet 4x4 posts is the wrong tool, and you'll chip teeth and slow yourself down proving it. Keep a 24-tooth blade for that work and this one for everything that shows.

Two blades in one pack is a small idea that fixes a real annoyance: 18 teeth for fast rips and rough framing, 24 for crosscuts, and neither pretending to do the other's job. If your saw takes 6-1/2-inch blades, this kit gets you through most of a weekend's work without a trip back to the store.

We reach for the 24-tooth first. It's the generalist, and in 2x material it leaves an edge clean enough for framing and decking. The 18-tooth is the one that changes how the saw feels: bigger gullets clear chips faster, so a pressure-treated 2x8 rips without the motor laboring. Both blades carry DEWALT's reinforced shoulder behind the carbide, which is the detail that matters when you're cutting pallets or reclaimed lumber with hidden nails.

Thin kerf and the Tough Coat finish do the same job they do on any good blade here: less material removed, less friction, cooler running, and a cordless saw that finishes the cut. The pair weighs about 11-1/2 ounces, so there's no penalty in the tool bag.

The limit is diameter. Six and a half inches is compact-saw territory, and this won't go near a full-size 7-1/4-inch saw. DEWALT lists it for its own saws, so match the arbor against your manual before ordering, because the blade can't tell you whether it fits.

Twenty-four teeth is the count that comes on most new 7-1/4-inch saws, and there's a reason for it: enough speed in framing lumber, not so rough that every cut needs cleaning up. This DEWALT is a direct replacement for that blade, built sturdier than the one in the box.

The reinforced shoulder behind each carbide tip is the part worth paying for. Cutting reclaimed lumber, or a pallet with a hidden nail, is where a blade earns or loses its place in the shop, and the extra braze material buys margin before a tip chips and the cut goes ragged.

Where this one earns its spot in the group is simplicity. The kerf is thin enough to keep a cordless saw moving, the anti-stick coating keeps pitch from building up, and at 9 ounces it adds nothing noticeable to the tool. Put it on, cut 2x stock and sheathing, and stop thinking about it.

It is still a 24-tooth blade, so plywood veneer and finish trim will show tear-out along the cut. That's the tooth count doing its job rather than a flaw, and if the edge is going to be seen, this isn't the blade for it.

Ten blades in one box changes how you treat a saw. When a fresh one is sitting in the case, you stop coaxing a dull blade through one more cut, and that habit alone is worth something.

The arithmetic is the real appeal. Per blade, these cost a fraction of what a premium single does, and they hold up better than that suggests: the 24-tooth grind took pressure-treated 2x and composite decking without chip-out in our cuts, with the thin laser-cut kerf keeping a battery saw from bogging down. Diameter, arbor, and speed are all spelled out at 6-1/2 inches, 5/8 inch, and 8,000 RPM, which are the first three things to check on any budget blade.

Each blade gets noise-reducing perforations and an anti-kickback tooth design, details that matter more on a light saw than on a worm drive. What the box doesn't have is a finish blade, since there's no 40- or 60-tooth option, so trim, melamine, and cabinet work still need a second purchase.

The honest trade is edge life. These go dull faster than premium carbide, and you feel it as burning and a slower feed before any tooth chips. For a crew working through decking and fencing, that's a fair exchange. For someone cutting a few boards a month, one good blade will outlast the whole pack.

Ten blades in one purchase is a commitment, and this pack earns it: a .059-inch kerf, laser-cut stabilizer vents, and a tracking-point tooth that Diablo builds for straight cuts under load. For someone framing a shed or decking a porch, it's the cheapest way to keep a sharp 24-tooth on the saw all season.

The .040-inch plate is what matters on cordless tools. Less steel in the cut means less drag, and Diablo's own figure for these blades is up to 30% more cuts per charge. Even allowing for some marketing in that number, a thin plate on a battery saw is the right call for a long day of crosscutting.

The tracking-point tooth sits at the front of the sequence and scores the outside corner of the kerf before the rest of the teeth follow, which is Diablo's answer to the wander a thin blade shows at speed. The stabilizer vents handle the other half, breaking up the vibration that makes a thin plate ring and drift in deep cuts.

What you give up is variety. Ten blades in one tooth count means you're set for framing and rough crosscuts and nothing else, so plywood, melamine, and trim still want a 40-tooth blade alongside the pack. Buy it for volume, not for range.
