The 07UMX bit is chosen to handle anything from limestone to taconite (3 to 8 on the Mohs scale of mineral hardness) and the 09UMX tackles slate to iron ore (4 to 9 on the Mohs scale). The UMX bits are designed to self-sharpen through the innovative crown matrix, which cuts away during drilling to expose new, large synthetic diamonds.

What is Blast Hole Drilling? Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.
