Supplier's note

  1. Technical Breakthroughs:

    • Material Innovation: 65Mn steel provides 30% higher tensile strength than standard carbon steel, extending tool life.
    • Precision Engineering: ER collet grooves reduce clamping slippage by 40%, critical for high-speed milling.
    • BT50 Compatibility: Universal fitment eliminates the need for adapter sleeves, saving setup time.

  2. Version Selection Guide:

    • Base Model: Ideal for small workshops or light-duty tasks (e.g., aluminum machining).
    • Advanced Model: Suited for precision shops requiring tight tolerances (e.g., aerospace components).
    • Pro Model: Triple the industry-standard load capacity (3,000N vs. 1,000N) enables heavy-duty machining of titanium or hardened steel. Pair with its 65HRC hardness for zero deformation in extreme conditions.

*Pro Model exceeds ISO 2959:2018 collet performance benchmarks by 50%.
