Abstract:A new type of diamond-impregnated PDC bit was developed according to the characteristics of medium hard rock formation. The cutting structure， and principle were introduced. The PDC cutting tooth and the diamond-impregnated rear support can strengthen the role of cutting action to improve the drilling efficiency and the bit stability in medium hard rock with long service life.
