【Product Name】The NACHI Cobalt HSS Morse Taper Shank Drill (Model: 6602) is a high-torque tool engineered for large-scale machining. It effectively addresses tool slippage in large diameters, rapid thermal wear in stainless steel, and stability issues in heavy-duty structural drilling.

【Key Features & Benefits】

• HSS-CO Thermal Stability: Crafted from Cobalt High-Speed Steel (HSS-CO), ensuring edge retention at extreme cutting temperatures. This is a practical recommendation for ISO M materials (Stainless Steel) where heat resistance is paramount.

• Morse Taper Shank Design: The tapered shank ensures maximum surface contact for superior torque transmission, preventing rotation in the holder during aggressive drilling cycles.

• 135° Point Angle for Reduced Thrust: The 135-degree point angle improves self-centering and reduces axial force, minimizing machine load while maintaining precision in large workpiece setups.

• 32~35° High Helix Geometry: Designed for efficient chip lift. For ISO N materials (Aluminum, Copper), it prevents the chip-packing and material welding common in large-volume material removal.

【Applications & Usage】

• Primary Applications: Ideal for lathe tailstock drilling, radial drills, and heavy-duty milling centers processing large industrial components.

• Recommended Materials:

  • ISO M (Stainless Steel): Tackles work-hardening and friction in tough alloys.

  • ISO P (Steel): Delivers stable performance for large structural and alloy steels under HRC30.

  • ISO N (Aluminum/Copper): Ensures smooth chip flow in soft, sticky non-ferrous metals.
