Key Features

• Cobalt Steel Construction: Engineered from cobalt high-speed steel, providing exceptional hardness, heat resistance, and extended tool life when working with demanding materials.
• Threaded Shank Design: Features a threaded shank for secure, wobble-free attachment to specialized drilling equipment, ensuring consistent performance and precision. This design minimizes slippage during high-torque operations.
• Long Series Length: The extended length facilitates drilling in deep holes or hard-to-reach areas where standard-length bits cannot access.
• 135° Split Point: Designed for rapid penetration and self-centering on contact, reducing bit "walking" and eliminating the need for a pilot hole in many applications.
• Aviation Grade Standards: Manufactured to rigorous industry standards such as NAS 965 Type D, ensuring reliability and performance for professional applications.

Applications

• Ideal for demanding tasks in aerospace and aviation maintenance, including structural repairs and fastener installations.
• Suitable for drilling into a wide range of tough materials such as stainless steel, titanium alloys, high-strength composites, hardened steel, and cast iron.
• Used in high-torque drilling operations where a robust and secure bit connection is critical.
• Effective for precision drilling in confined spaces or for angle and offset drilling tasks with compatible specialized drills.

Benefits

• Enhanced Durability: The cobalt alloy composition ensures superior resistance to heat and wear, significantly extending the drill bit's lifespan, especially in challenging drilling conditions.
• Superior Precision: The threaded shank provides a mechanically locked connection, virtually eliminating bit wobble and delivering consistently accurate and straight holes.
• Versatile Performance: Offers reliable drilling performance across a spectrum of hard and abrasive materials, making it a valuable tool for various industrial and aerospace applications.
• Optimized Access: The long series design, combined with its threaded shank for specialized tools, allows operators to achieve precise holes in deep or restricted locations.
• Efficient Drilling: The self-centering 135° split point initiates drilling quickly and cleanly, preventing deviations and contributing to faster, more efficient project completion.
