Irwin Marathon 14020 Carbide Circular Saw Blade, 18-tooth, 6-1/2 In.

The Irwin Marathon 14020 is a carbide-tipped circular saw blade designed for fast, clean cuts in wood and medium-thickness materials. The ultra-thin kerf design (0.063 inches) reduces material waste and delivers more cuts per charge when used with cordless power tools, while the face-ground, construction-grade carbide teeth maintain sharpness through extended use.

This 6-1/2-inch blade with 18 teeth features an aggressive hook angle for fast cuts. The precision-honed carbide tips resist dulling better than standard steel, and heat vents built into the blade design prevent excess heat buildup and pitch accumulation that can reduce cutting performance and tool lifespan.

Features and Benefits

• Ultra-Thin Kerf: At 0.063 inches, the thin blade profile delivers more cuts per charge on cordless saws and reduces material waste.
• Face-Ground Carbide Teeth: Construction-grade carbide tips are precision-honed to stay sharp longer and deliver fast, clean cuts.
• Aggressive Hook Angle: The blade geometry promotes rapid cutting action.
• Heat Vents: Strategically designed vents reduce heat buildup and prevent pitch or resin accumulation on the blade surface.
• 5/8-Inch Arbor: Universal arbor connection for circular saws.
