Irwin Marathon 24030 Circular Saw Blade, Carbide Tipped, 24-tooth, 7-1/4 In.

The Irwin Marathon 24030 is a 7-1/4-inch circular saw blade designed for portable corded saws and construction work. Built with 24 carbide teeth and a thin kerf design, this blade removes less material during cutting, enabling faster and cleaner cuts through wood and pressure-treated lumber. The construction-grade carbide teeth deliver longer blade life compared to standard options, making it well-suited for framing, ripping, and deck projects.

This blade features an innovative heat vent and expansion slot design that reduces vibration and keeps the blade cooler during operation, extending its lifespan and promoting straighter cuts with better accuracy. The silicone coating helps reduce pitch and resin buildup when cutting treated materials. A reinforced shoulder provides added durability, while maintained blade flatness ensures close tolerances and minimal wobble for precise cuts every time.
