The DEWALT 6-1/2' 40T Small Diameter Circular Saw Blade (DWA161240) is ideal for cross cutting applications. The exclusive, patent-pending ToughTrack tooth design on our framing and ripping blades is engineered to deliver straight, accurate cuts over the life of the blade. Patented body slots reduce vibration, which works with the 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 and durability by providing impact resistance against nail-embedded wood. These blades come with ToughCoat anti-stick coating to reduce friction and gumming and are optimized for use on both corded and cordless circular saws.
