The cobalt coating upon this aircraft extension high speed steel drill bit resists corrosion and abrasion. The bit is constructed of M-2 high speed steel for the best combination of strength, heat resistance, and wear resistance. It is ideal for drilling in hard-to-reach areas and for running wires and cable.
