Supplier's note

  1. Technical Breakthroughs:

    • Diamond Grit Density: The Pro model’s 156 grit outperforms industry standards, enabling 20% faster cutting in abrasive materials.
    • Hexagonal Shank: Reduces slippage by 40% compared to round shanks, ensuring stability in heavy-duty use.
    • Water Jet Efficiency: The Pro’s premium flow cools the bit 30% faster than competitors, preventing overheating.

  2. Optimal Version Selection:

    • Base Model: Ideal for occasional users (e.g., small-scale contractors) needing reliable performance at a lower cost.
    • Advanced Model: Perfect for medium-volume projects (e.g., road maintenance crews) requiring durability and moderate speed.
    • Pro Model: Designed for high-intensity applications (e.g., tunnel drilling) where extreme hardness and precision are critical. With triple the grit density of standard bits, it handles reinforced concrete with ease.

*Pro Model’s premium features exceed ISO 13399 benchmarks by 25%.
