Diablo CD1208DH Hardie 12" x 8-Tooth Ultimate Fiber Cement Blade

75x Longer Life. Polycrystalline Diamond Teeth. The Industry Standard for Hardie Board.

The Diablo CD1208DH is the ultimate cutting solution for James Hardie board and fiber cement products. While standard carbide blades dull almost instantly against the abrasive nature of cement, this 12" blade features specialized Polycrystalline Diamond (PCD) tipped teeth. These diamond tips provide an industrial-grade service life that is up to 75 times longer than standard blades, making it the most cost-effective choice for large-scale residential and commercial siding projects.

For the professional at The Fastener Group, the CD1208DH is also a critical safety tool. The unique 8-tooth configuration is engineered to produce significantly less respirable silica dust than high-tooth-count blades, helping you maintain a cleaner, safer jobsite while delivering the cleanest, most precise cuts in the industry.

Key Features & Professional Benefits:

• PCD Polycrystalline Diamond Teeth: Delivers unmatched durability and a 75x longer life compared to carbide, allowing you to finish an entire housing project with a single blade.
• Hardie-Specific Engineering: Designed in collaboration with James Hardie to ensure the perfect cut for all fiber cement siding, backer board, and trim products.
• Low-Dust Design: The ultra-minimal 8-tooth count creates larger chips and significantly less fine airborne dust, improving jobsite visibility and worker safety.
• Laser-Cut Stabilizer Vents: Traps noise and vibration to keep the blade running straight and cool, preventing the blade from "walking" through dense cement material.
• Perma-Shield™ Non-Stick Coating: Protects the blade from heat and friction, ensuring a smooth, effortless glide through the board even on hot summer days.
• Triple-Metal Shock-Resistant Brazing: Allows the diamond tips to withstand accidental impacts without fracturing, ensuring your investment is protected.
