Supplier's note

  1. Technical Breakthroughs:

    • TiCN Coating: Reduces friction by 25% compared to uncoated tools, enabling smoother reaming in titanium alloys.
    • Carbide Core: Maintains sharpness 50% longer than HSS-only reamers in abrasive materials.
    • Hex Shank Design: Ensures zero slippage in high-torque applications, critical for gun chamber alignment.

  2. Version Selection Guide:

    • Base Model: Ideal for general workshops needing cost-effective solutions for steel and aluminum.
    • Advanced Model: Best for medium-volume production requiring ISO P20 precision (e.g., automotive pistons).
    • Pro Model: Tailored for aerospace and firearms industries where 68 HRC hardness and microgroove flutes ensure ±0.002 mm tolerances in hardened steels.

With the Pro Model’s 68 HRC hardness, you can achieve 30% faster reaming in stainless steel compared to industry benchmarks. Pair its TiCN coating with the hex shank for unmatched stability in tight-tolerance applications.
