Marathon 6-1/2 in. D X 5/8 in. Classic Carbide Circular Saw Blade
IRWIN® circular saw blades last longer by design. New heat/vent expansion slots reduce vibration, providing longer life for the blade and straighter cuts for the user. A reinforced shoulder adds durability, and alternating carbide teeth are ground thinner for faster cutting and stay sharp longer. Every other tooth is ground thinner for fast cuts. Thicker plate design for improved tracking. Reinforced shoulder for durability and impact resistance. Body slots dissipate heat for long blade life.
