???????????? Made from high-purity tungsten carbide and premium cobalt, tungsten carbide mining buttons offer a hardness of HRA 88–93. The spherical structure optimizes stress distribution, significantly enhancing service life under high-impact conditions. They are suitable for high-speed, high-pressure rock drilling operations. Common applications include drill bits, cutting picks, anchor rod bits, and tunnel boring machines (TBMs), where they deliver excellent impact resistance and cutting performance.

????? Tungsten carbide button has the advantages of high hardness, high wear resistance, etc., and are widely used in oil drilling and snow plow equipment for snow removal. In addition, tungsten carbide buttons are also well used in cutting tools and mining machinery, road maintenance and coal drilling tools. Mining tungsten carbide buttons are mainly used as quarrying, mining, and tunneling and civil construction in the extraction tools. Tungsten Carbide Button Grade
