Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: Aluminum oxide combined with stainless steel provides 20% longer lifespan than standard discs.
    • Serrated Edge Design: Enables 30% faster corner sanding compared to flat-edge discs.
    • Aluminum Packaging: Reduces moisture-related damage by 40%, ensuring consistent performance.

  2. Optimal Version Selection:

    • Base Model: Ideal for DIYers and light industrial tasks requiring coarse grit (e.g., rust removal on small machinery).
    • Advanced Model: Suitable for professional workshops needing medium grit versatility (e.g., automotive refinishing).
    • Pro Model: Best for heavy-duty industrial use (e.g., aerospace metal finishing) with fine grit precision and extreme temperature resistance.

With the Pro Model’s 120 grit, you can achieve a mirror-smooth finish on metals, while its 120°C tolerance ensures reliability in high-heat environments. Pair its fine grit with the serrated edge to tackle complex geometries effortlessly.
