Supplier's note

  1. Three Technical Breakthroughs:

    • Carbide Substrate: Tungsten carbide ensures 20% longer lifespan than HSS tools.
    • Tin Coating: Reduces cutting temperature by 15%, extending tool life in continuous machining.
    • Triangular Geometry: Balances rigidity and chip evacuation for complex thread profiles.

  2. Optimal Version Selection:

    • Base Model: Ideal for general workshops machining aluminum or low-carbon steel.
    • Advanced Model: Suitable for medium-duty stainless steel or titanium alloys.
    • Pro Model: Required for high-speed, heavy-duty operations (e.g., Inconel) where extreme precision and longevity are critical.

With the Pro Model’s dual-layer coating, you can handle abrasive materials like cast iron while maintaining thread accuracy. Pair its high hardness with optimized flute geometry to reduce downtime by 30% in continuous production lines.
