Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: The HSS-alloy steel composite reduces thermal expansion by 20% compared to pure HSS, ensuring stable performance at high temperatures.
    • Precision Engineering: The STC thread class achieves 99.8% dimensional accuracy, surpassing ISO 965 standards.
    • Ergonomic Design: The handle hole reduces operator fatigue by 30% in prolonged use.

  2. Optimal Version Selection:

    • Base Model: Suitable for general workshops requiring cost-effective threading (e.g., small-scale metal fabrication).
    • Advanced Model: Ideal for precision engineering (e.g., aerospace components) needing tighter tolerances.
    • Pro Model: Recommended for heavy industries (e.g., automotive manufacturing) where extreme durability and high cycle counts are critical. With the Pro’s HRC 68 hardness, users can cut hardened steel alloys that would degrade standard dies. Pair its ±0.01mm precision with automated CNC systems to achieve zero-defect thread production.
