The DEWALT 8-1/4-inch 40-Tooth Cross-Cutting Circular Saw Blade (DWA181440) is a high-performance replacement blade designed for clean, fast cuts across the grain in lumber, plywood, and sheet goods. With high-density tungsten carbide teeth and a thin kerf design, this blade suits both corded and cordless 8-1/4-inch circular saws, making it a practical upgrade for DIY homeowners and finish carpenters who want smooth edges without spending on a specialty blade.
The 40-tooth configuration delivers smooth cross-cuts and reduces tear-out, while the thin kerf removes less material for faster cutting and easier feeding. High-density tungsten carbide teeth resist wear and keep the blade sharp longer, even when cutting abrasive or nail-embedded wood. A reinforced shoulder adds impact resistance, and the Tough Coat anti-stick coating prevents pitch and gum from building up.
Because the blade is thinner than a standard full-kerf blade, it requires less power and creates less waste. That makes it an excellent match for battery-powered circular saws, where preserving runtime matters.
The high-density tungsten carbide tips hold an edge longer than standard carbide, so you'll spend less time replacing blades and more time cutting. If you ever hit a nail, the reinforced shoulder helps prevent damage to the blade body.
The Tough Coat finish reduces friction while cutting, which lowers heat build-up and prevents resin from sticking to the blade. That means cooler, cleaner cuts in pressure-treated lumber and pine.
Pair it with a corded circular saw for continuous production cutting, or use it on a cordless saw to get more cuts per charge thanks to the low-drag design.
High-density tungsten carbide teeth: stay sharp longer and resist wear in abrasive materials.
Thin kerf design: removes less material for faster, cleaner cuts and less battery draw on cordless saws.
Tough Coat anti-stick coating: reduces friction, heat, and gumming for smoother cuts.
Reinforced shoulder: handles nail-embedded wood with less risk of damage.
Optimized for corded and cordless saws: works with most 8-1/4-inch circular saws.

Fewer teeth (18–24) make aggressive rip cuts for framing. More teeth (40–60) make finer crosscuts and cleaner finish work. The DWA181440's 40-tooth pattern is a balanced choice that works well for trimming, cross-cutting dimensional lumber, and breaking down sheet goods with minimal chipping.
This blade is optimized for cross-cutting – cutting across the grain. It will also handle general-purpose cutting, but if you're doing a lot of ripping (cutting with the grain), a dedicated rip blade removes material faster and reduces load on the saw.
It's designed for standard 8-1/4-inch circular saws with a 5/8-inch arbor. Check your saw's arbor size before ordering.
This is a cross-cutting blade, so it's best for cutting across the grain. For ripping, choose a 24-tooth rip blade for faster material removal.
No. The blade body is designed to stay rigid, and the thin kerf removes less material, which reduces cutting resistance and extends battery life on cordless saws.
Replace it when cuts start tearing instead of slicing, when it requires more pressure, or if you see chipped or missing carbide teeth.
Dude this blade is super sharp. Cross cuts are clean, no tearout. Definitely worth it.
I've used this on my miter saw for a few weeks now. It makes clean cross cuts in pine and oak. The thin kerf means less waste, but it does bend a little on thick stock. For the price, it's a good value.
I've been cutting wood for over forty years and this blade performs as well as any I've owned. The teeth stay sharp and the coating keeps the pitch from building up. It's a pleasure to use.
Love this blade! I built a shelf and some picture frames, no splinters. Also it's affordable compared to other brands.
It works fine for softwood, but I had some burning on oak. Maybe I expected more for a DeWalt.
Good blade.
It's sharp.
I bought this to replace the blade on my table saw. It makes nice cuts on plywood. However, I wish the arbor hole was bigger? But it fits my saw fine. Overall, happy.
This blade is tough. I've cut a lot of pressure-treated lumber and it hasn't lost its edge. Best blade I've had in years.
