Diablo HardieBlade 7-1/4 inch Fiber Cement Saw Blade - PCD Tipped, 4 Teeth, James Hardie Approved

Precision for fiber cement projects

The Diablo HardieBlade is built to handle fiber cement with ease. Its PolyCrystalline Diamond (PCD) tipped design and 4-teeth configuration are optimized for durability, clean performance, and consistent results on demanding materials. Approved by James Hardie Building Products, this blade is a trusted choice when the job requires reliability and accuracy.

Designed to work across all fiber cement products, this blade helps you cut faster and more precisely while maintaining surface integrity. The laser-cut thin kerf minimizes material waste, and the edge geometry is tuned to produce smoother cuts with less effort. A coating applied to reduce heat buildup keeps the blade cooler during long cuts, contributing to steadier performance under load.

• Up to 50% less respirable dust generation, supporting a safer and cleaner work environment when cutting fiber cement.
• James Hardie Approved: the only PCD-tipped blade endorsed for fiber cement by this leading manufacturer.
• Laser-cut thin kerf enables fast, precise cuts with reduced waste and less material handling.
• Anti-vibration design lowers noise and blade movement for smoother operation and less fatigue.

Real-world use and performance

In remodeling, siding installations, and demolition tasks, this blade can help you achieve tighter joints and cleaner edges.
