Supplier's note

1. Technical Breakthroughs:

   • 100° Angle Design: Reduces cutting resistance by 20% compared to standard 80° countersinks, enabling smoother chip evacuation.
   • HSS Core: Maintains hardness at 650°C, outperforming traditional carbide tools in high-temperature environments.
   • Threaded Shank: 30% stronger than industry benchmarks, ensuring zero slippage during heavy-duty drilling.

2. Version Selection Guidance:

   • Base Model: Best for general workshops requiring cost-effective solutions (e.g., small-scale metal fabrication).
   • Advanced Model: Ideal for medium-volume production lines needing 15% faster throughput (e.g., automotive part manufacturing).
   • Pro Model: Tailored for extreme applications like aerospace turbine assembly, where its 650°C resistance and 2,000-hole durability are critical.

*Pro Model’s speed advantage is validated against ISO 23692 drilling efficiency standards.
