Abstract As demands upon the earth's natural resources continue to grow, exploration companies, mining organizations and others face the problem of the need to tackle increasingly more difficult strata to open up new reserves. Innovations in materials technology and tool design have steadily improved this capability, but none perhaps so drastically as a recently introduced cemented carbide in which tool wear resistance and/or toughness can be tailored precisely to the user's drilling needs.
Keywords: Equipment design, Materials technology, Drilling equipment, Tungsten carbide, Cobalt.
