【Product Name】The NACHI Standard HSS Long Morse Taper Drill (Model: 650) is a high-versatility tool engineered for extended-reach and high-torque drilling. It primarily addresses the challenges of chip evacuation and stability in large-diameter, deep-hole applications where standard drills fall short.

【Key Features & Benefits】

• Morse Taper Shank Reliability: The tapered design ensures maximum surface contact for high torque transmission. This prevents tool slippage during aggressive drilling in large workpieces—a critical requirement for lathe tailstock operations.

• Extended Flute & 32~33° Helix: Designed with significant flute length to clear chips from deep cavities. The optimized helix angle provides superior lift, preventing chip packing that often leads to tool failure in deep penetration.

• Classic 118° Point Geometry: The proven point angle provides stable entry and balanced cutting force distribution. Supporting a max hardness of HRC30, it ensures consistent performance in structural and mechanical components.

• Premium HSS Toughness: Crafted from NACHI’s high-quality high-speed steel, this drill offers exceptional fracture resistance. It effectively dampens harmonic vibrations during extended reach, ensuring better hole straightness.

【Applications & Usage】

• Primary Applications: Ideal for large-scale industrial components, heavy-duty through-holes, and deep profile drilling on manual or automated radial drills and lathes.

• 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.
