【Product Name】The NACHI G 2-Flute Keyway End Mill (Model: 6244P L-Type) is a specialized tool engineered for high-precision keyway slotting and plunging, primarily addressing dimensional instability and tool deflection common in slotting operations.

【Key Features & Benefits】

  • 15-Degree Low Helix Advantage: The specialized 15-degree low helix design minimizes axial lifting forces and radial deflection. This ensures superior width consistency in keyway milling—a practical recommendation for maintaining tight tolerances.

  • Premium HSS-CO with G Coating: Crafted from Cobalt High-Speed Steel (HSS-CO) and enhanced with TiN (G) Coating, supporting performance up to HRC45. The coating improves surface hardness and lubricity, crucial for handling sticky ISO M Stainless Steel.

  • Superior Plunging Capability: The 2-flute geometry offers a large center chip space, facilitating efficient chip removal during vertical plunging and reducing the risk of tool failure due to chip packing.

  • Universal Material Support:

    • ISO P (Steel): Optimized for stable keyway cutting in structural steels under HRC30.

    • ISO M (Stainless Steel): Tackles material welding issues in high-ductility alloys like SUS304.

    • ISO K (Cast Iron): Provides excellent wear resistance against abrasive powdery chips.

【Applications & Usage】

  • Primary Applications: Ideal for high-precision keyway slotting in transmission components, plunge milling, and critical slotting where width accuracy is prioritized.

  • Recommended Materials: ISO P (Carbon Steel), ISO M (Stainless Steel), and ISO K (Cast Iron).
