Meet the Milwaukee 7-1/4 in. Polycrystalline Diamond Fiber Cement Blade—the tough, reliable solution for cutting fiber cement siding, backing, trim boards, and moldings with confidence. Designed for professional performance, this blade marries a rugged polycrystalline diamond edge with a precise 7-1/4" diameter and 5/8" arbor to deliver clean, consistent cuts in the most demanding fiber cement applications. Ready for speeds up to 8,000 RPM, it powers through abrasive materials without rapidly dulling, so you spend less time changing blades and more time on the job.
Why this blade stands apart
-
Polycrystalline Diamond edge: A durable PCD edge excels at cutting hard, abrasive fiber cement, delivering longer life and steadier performance than traditional carbide blades.
-
4-teeth configuration: The four-tooth design is optimized for aggressive cutting in fiber cement products such as siding, backing, trim boards, and moldings, helping you achieve faster, straight cuts with fewer passes.
-
FTG grind with 10° hook angle: The specific grind and hook angle promote smoother entry and reduced vibration, yielding cleaner edges and less chipping on delicate profiles.
-
Kerf and thickness: 0.071" kerf and a slim 0.05" blade thickness strike a balance between material removal and rigidity, enabling precise cuts with minimal waste.
-
Arbor and compatibility: 5/8" arbor size with Diamond Knockout arbor type ensures a secure, wobble-free fit on compatible circular saws designed for fiber cement work.
-
Speed and durability: Rated for up to 8,000 RPM, this blade maintains cutting performance across long days on site, reducing downtime and blade changes.
-
Single-blade packaging: Delivered as a single blade in a clamshell for easy visibility, storage, and portability when you’re navigating tight job sites.
Ideal use cases and practical benefits
- Perfect for professional remodeling and new construction projects where fiber cement products dominate the curb appeal—siding, soffits, trim, and decorative moldings.
- Provides straight, true cuts with minimal tear-out, helping you achieve showroom-ready edges without tedious touch-ups.
- Longer blade life translates to fewer tool changes and faster project completion in abrasive fiber cement materials.
- Low wobble and controlled cuts reduce user fatigue on long runs and improve overall cut quality in repetitive tasks.
Tips for best results
- Operate at appropriate speed (up to 8,000 RPM) and use steady, even feed pressure to maintain clean edges.
- Keep the cut dry and free of debris; let the blade do the work rather than forcing the saw through the material.
- Inspect the blade for signs of wear or damage after heavy use and replace if you notice chips, glazing, or dullness to preserve cut quality.
- Pair this blade with compatible dust collection and PPE to maintain a clean, safe work environment on fiber cement projects.
