Diamond Core Drilling Tools » Diamond Products » Diamond Impregnated Bits
Diamond impregnated bits are the most widely used bits in the core drilling industry. By adjusting the combination of metal powders and diamonds in the crown (or matrix), diamond impregnated bits can be manufactured to maximize penetration rates and bit life in a variety of rock formations. These variations are commonly identified by a series rating. As drilling progresses, the crown is slowly worn away, exposing new diamonds on the cutting surface. When the wear rate between the matrix material and the diamonds is balanced, optimum penetration rates and bit life will be achieved.
