Spherical Carbide Buttons: Precision Tools for Superior Performance
Introducing our high-quality carbide spherical buttons, meticulously crafted to elevate drilling and excavation operations to new levels of efficiency and effectiveness. These precision-engineered tools are designed to withstand the toughest conditions while delivering exceptional performance in various applications.
Cemented carbide is a composite material made of refractory metal hard compounds (WC, TiC, etc.) and bonding metals (CO, Ni, Fe, etc.) through powder metallurgy. Cemented carbide offers high hardness, high wear resistance, high strength, high modulus of elasticity, low coefficient of thermal expansion, high red hardness and stable chemical properties.
