About this product
The Diablo 12" x 8-Teeth HardieBlade Saw Blade for Fiber Cement is a professional-grade cutting solution engineered specifically for fiber cement siding, panels, and stacked cutting applications. Powered by a PolyCrystalline Diamond (PCD) triple chip design, this Diablo blade is the only PCD-tipped fiber cement saw blade exclusively approved by James Hardie Building Products - making it the go-to choice for contractors and installers who demand precision, longevity, and reduced dust exposure on every job site. Whether you are cross-cutting fiber cement siding or making repetitive production cuts on a miter saw or slide miter saw, the HardieBlade delivers clean, smooth results with drastically less blade wear than conventional carbide alternatives.
Key Features
- Exclusively approved by James Hardie Building Products as the only PCD-tipped fiber cement blade to earn their recommendation - gives professionals confidence that this blade meets the highest standards for fiber cement applications
- PCD triple chip design lasts over 75 times longer than standard carbide blades - dramatically reduces blade replacements and downtime on fiber cement siding and panel projects
- Reduces respirable dust by up to 50% - helps protect workers from hazardous airborne particles generated during fiber cement cutting (note: dust generation does not necessarily correlate directly to exposure risk)
- Triple Chip Grind (TCG) tooth geometry produces clean, smooth finishes with virtually no tear out - ideal for finish-quality cuts on fiber cement siding and panels
- Perma-Shield non-stick coating protects the blade against heat, gumming, and corrosion - extends blade life even under demanding, continuous use
- Tri-metal shock resistant brazing allows PCD tips to withstand extreme impact - maximizes durability in the abrasive conditions of fiber cement cutting
- Advanced stabilizer vents provide an ideal combination of stability and rigidity - ensures precise, consistent cuts and reduces blade flex during operation
- Laser-cut arbor reduces vibration and premature wear - promotes accurate blade rotation for straighter, cleaner cuts over the full life of the blade
- Compatible with corded and cordless miter saws - delivers more cuts per battery charge versus standard blades, extending tool runtime on battery-powered equipment
- Precision laser-cut thin kerf at.087" - minimizes material waste and reduces cutting resistance for faster, more efficient throughput
Why This Product
- The only PCD-tipped fiber cement blade with exclusive James Hardie endorsement - professionals installing HardiePlank, HardiePanel, or other James Hardie products can use this blade knowing it is purpose-approved for those exact materials
- A PCD cutting edge that outlasts standard carbide by more than 75x means fewer blade changes, lower long-term tooling costs, and less interruption during large fiber cement siding installations
- The combination of dust reduction technology and a thin.087" kerf makes this blade a practical choice for job sites where air quality and material waste are ongoing concerns
- Engineered for both miter saws and slide miter saws at up to 6000 RPM, this blade fits seamlessly into the tool setups most siding contractors already use - no special equipment required
