Cobalt drill bits are high-performance tools made with cobalt steel and used in heavy-duty applications, including industrial manufacturing and automotive repair. M42 cobalt drill bits are a specific variety of cobalt drill bits comprised of 8 percent cobalt and M42 high-speed steel, and they offer superior hardness and heat resistance. 

Large cobalt drill bits can withstand the rigors of drilling into particularly hard, abrasive materials without breaking or getting excessively worn out. With the bit’s entire body being composed of the robust M42 cobalt compound, our large cobalt drill bits have greater longevity and better performance, as there’s no risk of a coating wearing off over time.
