【Product Name】The NACHI Standard HSS Morse Taper Shank Drill (Model: 602) is a versatile tool engineered for high-torque general-purpose drilling. It primarily addresses tool slippage and rigidity issues encountered in large-diameter applications on lathes and radial drills.

【Key Features & Benefits】

  • Morse Taper Shank Stability: The tapered shank provides superior friction contact for maximum torque transmission. It ensures the drill remains locked in the spindle during aggressive drilling cycles, making it a reliable choice for heavy components.

  • Classic 118° Point Geometry: The proven point angle offers balanced cutting forces and steady entry. Supporting a max hardness of HRC30, it is ideal for most structural and mechanical drilling tasks.

  • 32~34° Optimized Helix: Designed specifically to manage chip lift in larger cavities. For ISO N materials (Aluminum, Copper, Plastics), it ensures efficient evacuation and prevents material welding on the flutes.

  • Proven HSS Toughness: Crafted from NACHI’s premium high-speed steel, this drill offers exceptional fracture resistance. It is highly forgiving in manual setups or older machinery, providing a cost-effective solution for workshop operations.

【Applications & Usage】

  • Primary Applications: Ideal for lathe tailstock drilling, radial drills, and general-purpose large-scale metal fabrication.

  • Recommended Materials:

    • ISO P (Steel): Carbon steel, structural steel, and alloy steels under HRC30.

    • ISO N (Aluminum/Non-ferrous): Aluminum 6061/7075, copper, brass, and plastics.
