7-1/4" x 4T PCD Hardie Fiber Cement Blade

Diablo HardieBlade is the only approved PCD (PolyCrystalline Diamond) tipped fiber cement blade recommended by James Hardie Building Products. Diablo's co-branded Diablo blade generates up to 5% less respirable dust*, while delivering the longest life in all fiber cement materials. The PCD triple chip design offers up to 60-times longer cutting life than standard carbide blades. The laser cut thin kerf design gives fast and precise cuts with less dust and waste. The anti-vibration design stabilizes the blade and reduces noise while cutting and non-stick Perma-Shield coating to reduce heat.
