CRALY 7-1/4 in PCD Hardie Fiber Cement Blade - Long Life Cutting

In this review the CRALY 7-1/4 in polycrystalline diamond tipped (PCD) blade is evaluated for tradespeople and serious DIYers who cut fiber cement, hardie plank, MDF and similar dense materials. The bottom line: this blade is built for longevity and clean cuts - its PCD teeth and BLACK ICE coating deliver vastly longer life than standard carbide alternatives while reducing heat and friction for a smoother cutting experience.

Key Features

• PCD teeth: Polycrystalline diamond tips deliver extremely long cutting life and keep the edge much longer than carbide alternatives.
• Thin kerf: The 1.8 mm thin kerf reduces material waste and requires less power from your saw, producing faster cuts.
• BLACK ICE coating: Anti-stick, low-friction coating reduces heat build-up and corrosion for cleaner cuts and extended blade life.
• Laser-cut stabilizer slots: Expansion slots and stabilizer vents lower vibration and noise to improve cut precision and control.
• 5/8 in arbor fit: Standard arbor size ensures compatibility with most circular saws and many table saws used on job sites.

Who It's For

The blade is best suited to contractors, remodelers and serious DIYers who regularly cut fiber cement board, hardie plank, Eternit, Corian and dense composite sheet goods and want a blade that lasts far longer than carbide options. It pays off where frequent blade changes interrupt workflow or where cutting life and cut quality are priorities.

Less suitable for casual users who rarely cut hard materials or who primarily cut softwood and general-purpose lumber; for general framing or trim work a more economical carbide blade optimized for wood will be a better fit.

Pros & Cons

Pros

• Exceptional wear life from PCD teeth, meaning fewer blade changes on long jobs.
• Thin kerf and stabilizer slots reduce vibration and produce precise, faster cuts.
• BLACK ICE non-stick coating lowers heat and resists corrosion for cleaner cuts.

Cons

• Specialized PCD design is overkill for routine wood cutting, making it an inefficient choice for general carpentry.

Specifications

Our Verdict

The CRALY 7-1/4 in PCD hardie blade is a strong choice for professionals and dedicated DIYers who cut fiber cement and other very hard sheet goods. Its PCD teeth and BLACK ICE coating deliver durable, low-friction performance that reduces downtime and produces clean cuts, making it good value for heavy users despite being specialized for hard materials.

Frequently Asked Questions

Will this blade fit a standard circular saw?
Yes; the blade uses a 5/8 in arbor which matches most circular saws and many table saws.

Is it good for cutting wood?
It will cut wood, but the PCD design is optimized for fiber cement and super-hard materials, so a general-purpose carbide blade is better for routine woodwork.

How much longer does the PCD tip last?
PCD tips offer substantially longer life than standard carbide tips, making them ideal for heavy cutting schedules and reducing the need for frequent blade changes.
