Tungsten carbide is used in many drilling and mining fields. High resistance to wear is demanded in drilling, milling, trenching, and cutting. We offer an extensive product line, including many dimensions and shapes that are constantly used on drilling and mining tools. We also manufacture tungsten carbide/ hard alloy buttons in special shapes for certain applications.
