【Product Name】The NACHI AG 4-Flute Standard Shank End Mill (Model: 6496) is a professional tool engineered for stability and long tool life, primarily addressing edge wear, vibration, and surface quality challenges in high-ductility materials.

【Key Features & Benefits】

• Enhanced 4-Flute Rigidity: The 4-flute design offers a larger core diameter, ensuring superior tool stiffness. This minimizes deflection during side milling and maintains strict dimensional accuracy—a practical recommendation for finishing tasks.

• HSS-CO Base with AG Coating: Crafted from Cobalt High-Speed Steel (HSS-CO) and enhanced with the proprietary AG coating, supporting performance up to HRC45. The coating boosts thermal resistance and lubricity, which is essential for handling sticky ISO M Stainless Steel.

• Engineered for Stainless Performance: Optimized for SUS304, SUS316, and SUS420. Its 30-degree helix angle ensures even distribution of cutting forces, reducing the impact of work hardening on the tool's life cycle.

• Balanced Toughness & Reliability: Compared to carbide tools, HSS-CO provides better shock resistance, making it more forgiving in standard machine setups. Ideal for general-purpose machining of structural steels under HRC30.

【Applications & Usage】

• Primary Applications: Ideal for high-quality profiling, side finishing, and general external milling where surface gloss is a priority.

• Recommended Materials:

  • ISO M (Stainless Steel): Tackles material welding and thermal friction issues in high-ductility alloys.

  • ISO P (Carbon/Alloy Steel): Best for general-purpose high-quality cutting of structural steels.
