1. Three challenges in fiber cement board cutting

Fiber cement board is usually made from cement, cellulose fiber, silica sand, or mineral fillers. This makes it much more abrasive than ordinary wood-based panels.

Fast tooth wear.
Hard mineral particles inside the board continuously rub against the blade tips. For standard TCT blades, this can cause faster dulling, more heat, and higher cutting resistance.

Dust control.
Dry cutting fiber cement board can generate fine dust that may contain respirable crystalline silica. For factory cutting, dust extraction, wet cutting, and proper protection should be considered together with cutting efficiency.

Edge chipping.
Fiber cement board is relatively brittle. If the blade is not sharp enough or chip evacuation is poor, the cutting edge may chip or become rough, affecting installation quality and finished appearance.

2. Why PCD is a better choice

PCD, or polycrystalline diamond, is a super-hard cutting material designed for abrasive applications. Compared with standard carbide, its key advantage is not simply aggressive cutting, but much stronger wear resistance during long cutting runs.

For jobsite cutting and small-to-medium processing needs, the Nakamura 184mm Fibre Cement Blade is a practical option. Its low-tooth-count PCD design and larger gullets are suitable for fiber cement siding, backer board, and mineral-based panels.

3. Nakamura focuses on production efficiency, not just blade life

For factories, the real cost is not only the price of one blade. Downtime, rework, unstable cutting quality, and frequent blade replacement all increase total production cost.

The Nakamura PCD Fiber Cement Circular Saw Blade is designed for abrasive cement-based boards. Its PCD tips help extend cutting life, while deep gullets support smoother chip evacuation during continuous cutting.

A sharper and more durable cutting edge can help reduce chipping. Better chip removal can reduce heat and cutting resistance. Fewer blade changes can keep production moving more steadily.

4. The right blade makes fiber cement cutting more controllable

Fiber cement board is not impossible to cut. It simply requires the right blade design.

For bulk processing, custom specifications, or long-term supply needs, the Nakamura Fiber Cement Board Saw Blade is a strong choice for fiber cement board, gypsum-bonded panels, and other abrasive sheet materials.

Choosing the right blade means fewer stoppages, fewer rough cuts, and less wasted material. With Nakamura PCD saw blades, fiber cement cutting becomes more stable, efficient, and controllable.
