Diablo D0704DH 7-1/4" x 4-Teeth HardieBlade Saw Blade for Fiber Cement redefines how you cut fiber cement. This is the groundbreaking blade that professionals trust for cleaner edges, faster cuts, and dramatically less dust. As the exclusive PCD-tipped blade endorsed by James Hardie Building Products, it’s purpose-built to tackle the toughest fiber cement jobs with precision and reliability.

Why this blade matters on the job site:

• Exclusive PCD tip endorsed by James Hardie — a proven solution for fiber cement that delivers consistent performance and long life.
• Dust reduction up to 50% of respirable particles, helping keep your workspace safer and cleaner.
• PCD triple chip design— engineered to outlast standard carbide blades by a wide margin, giving you hundreds more cuts per blade.
• Precision laser-cut thin kerf — enables faster, smoother cuts with less material waste and minimal tireless rework.
• Anti-vibration technology — stabilizes each cut, reduces noise, and lowers operator fatigue on long runs.
• Non-stick Perma-Shield coating — provides excellent heat resistance and makes cleanup easier, so you stay productive.
• Optimized for fiber cement applications — delivers consistent, accurate results on siding, panels, and trim without chipping or splintering.

Real-world use cases

installers cutting HardiePlank or similar fiber cement siding will notice faster plumb cuts with cleaner edges. Siding panels and trim sections become easier to fit when you’re making repeated crosscuts and rip cuts on dry runs. The combination of low dust, long blade life, and stable cuts translates to fewer pauses for blade changes and more time getting the job done right the first time.

Designed for professionals who demand more

The HardieBlade’s advanced construction is ideal for contractors, remodelers, and carpenters who routinely work with fiber cement and won’t settle for ordinary blades. If you’re seeking a blade that reduces dust, extends service life, and preserves cut quality across hundreds of cuts, the Diablo D0704DH is built for you.

Performance you can feel and trust

Compared with standard carbide blades, this blade’s PCD tip and triple chip design deliver a noticeable edge in durability and edge quality. The thin kerf minimizes waste, and the anti-vibration system maintains smoother operation even on longer cuts. With the Perma-Shield coating, heat buildup is mitigated, keeping the blade cooler and improving overall performance in demanding fiber cement jobs.

Tips for optimal results

• Keep cuts steady and let the blade’s geometry do the work—don’t force the saw through tough sections.
• Use clean, dry material and allow for proper ventilation to maximize dust reduction benefits.
• Inspect the blade for wear after heavy use; the PCD-tipped edge is designed for longevity, but regular checks ensure consistent results.
