ABSTRACT:
The present invention provides a diamond impregnated bit with an adaptive matrix in the ribs. The ribs have at least two different areas of metal-matrix composite impregnated with diamonds with different wear resistance such that during boring of formation, the areas will wear at different rates and provide fluid flow spaces across the surface of the ribs.
