Supplier's note

  1. Technical Breakthroughs:

    • High-speed steel core: Delivers 20% faster wear resistance than traditional blades, extending tool life in continuous operation.
    • Precision edge tolerance (±0.01mm): Enables flawless slitting for high-volume paper production.
    • Triple-industry-standard chemical resistance (Pro model): Safely handles corrosive fluids in lab and chemical processing.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard paper cutting in low-stress environments (e.g., office machinery).
    • Advanced Model: Suited for medium-duty industrial use where precision and moderate chemical exposure are key (e.g., packaging lines).
    • Pro Model: Designed for heavy-duty applications requiring extreme durability, such as cutting abrasive materials or operating in high-heat/chemical labs. With its HRC 68 hardness, the Pro version outperforms competitors in edge retention and resistance to deformation.

*Comparative benchmarks: Industry standard chemical resistance = 500 hours in pH 2 solution; Pro model achieves 1,500 hours.
