Supplier's note

  1. Three Technical Breakthroughs:

    • Expandable Radius Range: The Pro Model’s R3–R10 capability exceeds industry-standard R6 limits, enabling designs for both delicate and bold applications.
    • Die Durability: The Pro’s hardened tool steel dies resist wear, maintaining precision even after 10,000+ uses—twice the lifespan of plastic dies.
    • Quick-Swap Mechanism: The Pro’s magnetic die lock reduces die change time by 40% compared to traditional screw-based systems.

  2. Optimal Version Selection:

    • Base Model: Ideal for hobbyists or low-volume projects needing basic radii (R3–R6).
    • Advanced Model: Suitable for small businesses requiring mid-range durability (e.g., craft studios).
    • Pro Model: Best for professional workshops handling heavy use or demanding precision (e.g., leather goods manufacturing).

With the R30’s interchangeable dies, you can tailor corner radii to match client specifications. The Pro Model’s chemical-resistant dies also ensure longevity when working with treated materials. Pair its heavy-duty build with leather compatibility to create durable, professional finishes.
