are rubber sealed journal bearing bits. The bits are adaptable for high WOB under normal RPM condition. With different cutting structure designs, this series bits are suitable for drilling very soft to very hard formations. High strength and high toughness carbide inserts are used on insert bits to achieve better wear resistance and excellent cutting abilities. New type of hardfacing material is applied to steel tooth bits to extend service life of the bit.
