tricone drill bits are designed for the most severe rotary blasthole applications, but are cost-effective for a wide range of drilling needs. The new bit lines include six diameters from 200mm (7 7/8 inches) to 311mm (12 1/4 inches).

Blasting drilling is a technique used in mining. By this technique, a hole is drilled in the surface of the rock, filled with explosives, and then detonated. The purpose of this technique is to induce fractures in the internal geology of the surrounding rock to facilitate further drilling and associated mining activities.
