The high-density cloth tooth natural impregnated diamond core drill bit is suitable for core drilling in extremely hard and highly abrasive formations. Fine grained natural diamonds are embedded in the matrix, and the matrix material with appropriate hardness maintains a suitable amount of wear throughout the drilling process, ensuring optimal diamond exposure and efficient cutting of the formation. The rock breaking mechanism of impregnated diamond drill bits is to grind formation rocks, requiring greater drilling pressure and faster rotation speed during drilling. Natural diamond has poor thermal stability and is only suitable for liquid drilling. Gas drilling can cause early damage to the drill bit, making it more suitable for coring in hard formations
