Supplier's note

  1. Three Key Breakthroughs:

    • Segmented Design: Enables precise radial expansion for tight tolerances, reducing tool misalignment.
    • Titanium Coating (Pro): Offers 3x longer lifespan in high-temperature environments compared to standard steel.
    • Universal Compatibility: Works across 9+ machine types, eliminating the need for multiple mandrel sets.

  2. Optimal Version Selection:

    • Base Model: Ideal for small workshops or light-duty CNC operations (e.g., plastic cutting).
    • Advanced Model: Suitable for medium-scale manufacturing needing higher RPM (e.g., aluminum milling).
    • Pro Model: Best for heavy industries requiring extreme durability (e.g., aerospace titanium machining). With its 700 N clamping force, it prevents tool slippage even at 5,000 RPM.

Comparative Hint: Pro Model’s clamping force exceeds industry standards by 40%, ensuring superior stability.
