Maximize your cutting efficiency on the jobsite with the IRWIN Classic 7-1/4" 24T Circular Saw Blade.
Built for professional framers, carpenters, and general contractors, this 24-tooth construction saw blade excels at fast, aggressive ripping and general dimensional lumber cutting. The precision-ground carbide teeth stay sharp under heavy jobsite use, cutting smoothly through 2x material, subflooring, sheathings, and engineered wood without straining your saw motor.
Featuring a standard 5/8-inch arbor hole, this blade is fully compatible with most standard 7-1/4" corded and cordless circular saws. Its high-leverage 19-degree hook angle pulls material smoothly through the blade for reduced user fatigue and faster cut speeds up to its maximum rating of 8,300 RPM.
