Threaded Shank Cobalt Drill Bits for Aircraft Maintenance

Threaded Shank Adapter Drills are manufactured to NAS 965 Type D Standards with 135 Degree Split Points.  Cobalt Drills are for drilling hard, tough, high tensile strength materials and have a significantly longer tool life than regular High Speed Steel.  Industry standard 1/4 - 28 threads.

Threaded shank cobalt drill bits are essential tools in aircraft maintenance due to their durability, precision, and compatibility with power-driven drill systems commonly used in aviation. These drill bits, made from high-speed steel with cobalt alloying, offer superior hardness and heat resistance, making them ideal for drilling into tough materials such as titanium alloys, stainless steel, and high-strength composites used in modern aircraft structures. The threaded shank design ensures a secure fit in threaded adapters, minimizing the risk of slippage during high-speed drilling operations and providing consistent performance in demanding environments. Aircraft maintenance often requires precise drilling for tasks like structural repairs, fastener installations, and component replacements, where accuracy and reliability are critical to ensuring the integrity of the aircraft. The robustness and precision of threaded shank cobalt drill bits make them indispensable for meeting the rigorous standards of safety and performance in aviation maintenance.
