Diablo HardieBlade? is the only approved PCD (Polycrystalline diamond) tipped fiber cement blade recommended by James Hardie Building Products. Diablo fiber cement blades generate up to 5% less respirable dust, while delivering the longest life in all fiber cement materials. Diablo PCD Hardieblades feature a unique, spark-eroded triple chip grind for long life up to 60X the life in fiber cement of conventional carbide blades Diablo PCD Hardieblades are ideal for full time use in heavy-duty applications like cutting multiple pieces of fiber cement board. Dust generation does not necessarily correlate directly to exposure risk.

Polycrystalline diamond tipped teeth provides longer life for less dust; lasts up to 15 times longer and will cut up to 9000 ft of fiber cement or 5 stacks of fiber cement.
