Tungsten Carbide Drill Description
Tungsten carbide drills are composed of a compound containing an equal number of tungsten and carbon atoms. The simplest form of tungsten carbide is a fine grey powder. It is processed using a sintering method and pressed into defined shapes. These shapes are used in industrial machinery, cutting tools, abrasives, armour‐piercing projectiles and jewellery. Tungsten carbide drills are produced to meet the requirements of mining, tunnel construction and the building industry.
