Irwin Marathon 40T carbide circular saw blade for corded 7-1/4" circular saws. Tooth count sets the trade-off: fewer teeth cut faster and leave a rougher edge, more teeth cut slower and leave a smoother one. Heat vent and expansion slots reduce vibration for longer blade life and straighter cuts, and a reinforced shoulder adds durability.
