Diablo HardieBlade 4-Tooth PCD Fiber Cement Circular Saw Blade

The Diablo HardieBlade™ is a 4-tooth PCD (PolyCrystalline Diamond) tipped circular saw blade for cutting fiber cement siding, trim, soffit and other James Hardie building products. It is the PCD-tipped blade endorsed by James Hardie Building Products, reduces respirable dust by up to 50%* and lasts over 75 times longer than standard carbide blades.

Choose 6-1/2 in. (D0604DHA) or 7-1/4 in. (D0704DHA) to match your circular saw. Both sizes use the same 4-tooth PCD triple chip design, thin kerf, anti-vibration plate and Perma-Shield coating. D0604DHA and D0704DHA are the packaged versions of Diablo D0604DH and D0704DH; the blades are identical.
