【Product Name】The NACHI AG Square Tooth Roughing End Mill (Model: 6402) is a powerful tool engineered for high-volume cutting. It primarily addresses chip evacuation issues, thermal buildup, and vibration during the heavy-duty machining of stainless steel and structural steel.

【Key Features & Benefits】

• Square Tooth Profile: Features a specialized Square Tooth wave geometry that effectively fragments tough, stringy chips into smaller pieces. This significantly reduces cutting resistance—a practical recommendation for stable heavy-duty milling.

• Variable Helix Design: The 30~32 degree variable helix disrupts harmonic vibrations. This ensures smoother operation during deep slotting or high-feed milling compared to standard tools, resulting in better process control.

• High-Toughness HSS-CO: Made from Cobalt High-Speed Steel (HSS-CO), offering superior impact strength. It is more forgiving in less rigid machines or interrupted cutting setups, preventing the sudden edge failure common in carbide tools.

• Premium AG Coating: Equipped with the proprietary AG coating, supporting performance up to HRC45. Its excellent heat resistance and anti-sticking properties make it highly recommended for ISO M Stainless Steel (SUS304/316).

【Applications & Usage】

• Primary Applications: Ideal for high-efficiency bulk material removal, heavy-duty slotting, and aggressive profiling of precision components.

• Recommended Materials:

  • ISO P (Steel): Best for general carbon and alloy steels under HRC30.

  • ISO M (Stainless Steel): Tackles high-ductility materials where efficient chip breaking is critical.
