Supplier's note

  1. Three Technical Breakthroughs:

    • Ceramic Coating: Reduces friction by 30% compared to uncoated tools, enabling 20% faster cutting speeds.
    • Hexagonal Shank: Provides 15% better clamping stability than round shanks, minimizing vibration in deep hole boring.
    • Custom Diameter Tolerance: Allows adjustment to ±0.001 mm for medical implant machining, exceeding ISO 2768-m tolerance standards.

  2. Optimal Version Selection:

    • Base Model: Ideal for general workshops machining aluminum or mild steel (e.g., automotive parts).
    • Advanced Model: Suited for automotive engine block manufacturers needing 20% longer tool life in cast iron.
    • Pro Model: Required for aerospace applications where ±0.002 mm tolerances are critical (e.g., turbine blade boring). The Pro’s ceramic coating triples wear resistance, ensuring safe handling of titanium alloys at 5,000 RPM.
