Irwin Marathon 24130 Circular Saw Blade, Carbide-tipped, 24t, 7-1/4-in.

The Irwin Marathon 24130 is a 7-1/4-inch carbide-tipped circular saw blade engineered specifically for cutting pressure-treated lumber with precision and durability. The 24-tooth carbide cutting edge delivers clean, fast cuts while the special coating minimizes pitch and buildup that accumulates when working with treated wood, extending blade life and reducing maintenance downtime.

This blade solves common frustrations encountered when cutting pressure-treated lumber: overheating from pitch accumulation, vibration causing wandering cuts, and premature dulling. The thin kerf design (0.071 inches) works efficiently with portable corded saws, while the reinforced shoulder construction provides added durability for demanding applications.

Features and Benefits

• Deep Gullets: Remove chips and debris quickly to reduce heat buildup and extend blade life during extended cutting sessions.
• Heat Vent and Expansion Slot Design: Reduces vibration for longer blade life and straighter, more precise cuts on every pass.
• Pressure-Treated Wood Coating: Special coating resists pitch and buildup, keeping the blade cleaner and sharper longer when cutting treated lumber.
• Carbide Cutting Edge: Construction-grade carbide teeth maintain their edge through repetitive cuts in abrasive treated wood.
• Thin Kerf: 0.071-inch thickness for use with portable corded saws.
• Reinforced Shoulder: Provides added durability for consistent performance.
