- Wire size drill bits are drill bits that are measured by a standard wire gauge system. There are different types of wire size drill bits, such as high-speed steel (HSS), titanium, and cobalt. Cobalt wire size drill bits are made of cobalt high-speed steel, which is a type of alloy that contains 5% to 8% cobalt. Cobalt drill bits are designed for drilling in tough, high tensile strength materials, such as stainless steel, titanium, and inconel. Cobalt drill bits have a heavy-duty flute construction and a 135° split point, which helps prevent the bit from wandering and reduces the amount of pressure required to penetrate the material. Cobalt drill bits are also more resistant to heat and wear than HSS or titanium drill bits, which makes them suitable for high-temperature applications. Cobalt drill bits are commonly used in aircraft, aerospace, and automotive industries, where precision and durability are essential.
