Industrial Diamond Precision: The Only James Hardie Approved Blade for Clean, High-Speed Fiber Cement Cutting

The Diablo D0704DHA 7-1/4" HardieBlade™ is the industry-leading solution for professionals demanding ultimate performance in rigorous fiber cement applications. As the exclusive PCD (PolyCrystalline Diamond) tipped blade officially endorsed by James Hardie Building Products, it sets a new standard for longevity and safety. This powerhouse blade features an innovative PCD triple chip design that lasts over 75 times longer than standard carbide blades, ensuring you spend more time cutting and less time replacing tools on the jobsite. Additionally, the advanced design reduces respirable dust by up to 50%, promoting a cleaner work environment without sacrificing speed.

Engineered for both corded and cordless circular saws, the HardieBlade™ utilizes a precision laser-cut thin kerf to empower professionals with fast, accurate cuts and minimized material waste. The blade is equipped with Diablo's exclusive Perma-SHIELD® non-stick coating, which provides exceptional heat resistance and protects against gumming and corrosion. To ensure every cut is stable and quiet, advanced stabilizer vents and tri-metal shock-resistant brazing work together to neutralize vibration and withstand extreme impacts. Whether you are installing siding or backing boards, this blade delivers clean, smooth finishes with virtually no tear-out.

Pro-Tip: To maximize the dust-reduction capabilities of the HardieBlade™, ensure your circular saw is equipped with a dust collection bag or a vacuum attachment. Because fiber cement is highly abrasive, using a PCD diamond blade at the correct RPM will prevent the heat buildup that typically dulls standard carbide blades within just a few cuts.
