Our carbide drill bit mining teeth are specifically designed for harsh mining environments. Made from high-quality tungsten carbide and cobalt through special sintering processes, they have a hardness of over HRA90 and possess excellent wear resistance and impact resistance. The unique tooth shape design is tailored to different rock characteristics, and the crushing efficiency is 30% higher than that of ordinary mining teeth. Whether it is coal mining, iron mining, or gold mining, they can operate stably and efficiently, greatly reducing mining costs and extending the service life of equipment. They are the ideal choice for your mining operations.
