【Product Name】The NACHI 4-Flute Standard Shank End Mill (Model: 6210) is a high-rigidity tool engineered for stable cutting performance, primarily addressing deflection and chatter marks common in side milling applications.

【Key Features & Benefits】

• Enhanced 4-Flute Rigidity: The 4-flute design offers a larger core diameter, ensuring superior tool stiffness. This results in better straightness and surface integrity during profiling—a practical recommendation for achieving consistent dimensional accuracy.

• High-Toughness HSS-CO: Made from Cobalt High-Speed Steel (HSS-CO), providing excellent impact resistance. It is much more forgiving than carbide tools in conventional setups, preventing sudden failure during interrupted cuts.

• Sharp Uncoated Finishing: The uncoated edge provides ultimate sharpness. This is essential for ISO N materials (Aluminum 6061/7075, Copper, Plastic) to minimize cutting resistance and avoid burr formation on the workpiece.

• Practical Versatility: An ideal choice for machining structural steels under HRC30. It is a reliable standby tool for general-purpose machining and secondary finishing operations.

【Applications & Usage】

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

• Recommended Materials:

  • ISO N (Aluminum Alloys, Copper, Brass): Optimized for clean cutting of 6061 and 7075 aluminum.

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