The DEWALT 8-1/4" 40T Small Diameter Circular Saw Blade (DWA181440) is ideal for any wood-cutting application. The exclusive, patent-pending ToughTrack tooth design, on our framing & ripping blades, is engineered to deliver straight, accurate cuts over the life of the blade. Patented Body Slots reduce vibration, which works with the circular saw blade's thin kerf design to deliver exceptional user feel. High-Density Tungsten Carbide teeth are tough, wear-resistant, and provide long life. The reinforced shoulder is designed for strength & durability by providing impact resistance, especially in nail-embedded wood. These circular saw blades come with ToughCoat™ anti-stick coating to reduce friction and gumming. Optimized for use on both corded and cordless circular saws.
