Irwin 14130 Marathon Carbide-tipped Circular Saw Blade, 24-tooth X 7-1/4 In.

The Irwin 14130 Marathon is a carbide-tipped circular saw blade designed for cutting lumber and pressure-treated decking with a portable corded saw. The 7-1/4 inch diameter blade with 24 carbide teeth is ready for deck and fence work.

This blade features a thin kerf design (0.071 in.) and includes a heat vent and expansion slot design that reduces vibration for longer blade life and straighter cuts. The reinforced shoulder adds structural support, while the alternate top bevel tooth geometry with a 20-degree hook angle balances cutting performance. The deep gullets help remove debris quickly to prevent pitch and material buildup on pressure-treated cuts.
