PDC rotary rock bit Characteristics: high wear resistance and impact-resistant toughness, long drilling life, drilling efficiency can be promoted sharply in penetration of soft and medium soft formation, laber intensity can be reduced. The GK PDC inserted oil drill bits with high strength and high toughness carbide gear, optimized design of the tooth row number, gear, toothy height and unique alloy tooth shape, give full play to the high wear resistance and excellent cutting ability of the bits. The GK PDC inserted oil drill bits face apply welding new wear-resistant materials, to keep high mechanical penetration rate of the bits, at the same time, improve the drill bits GK PDC cutters life. New products with our GK PDC cutter and SDB PDC cutter. Characteristics 1) Super long life-as 10 times as cemented carbide drill bits under the same condition. 2) High efficiency-Times of lifting the drilling machine could be reduced sharply, and the average time efficiency could be increased more than 2 times. 3) Wide range of application-it could have a penetration of rock formation with f ≤12, especially for the rock formation with f=5-10. Service: Guilin Star Diamond can supply all kinds of PDC coring and non-coring bits, PDC oil bits and PDC anchor bits. PDC bit can be widely used in the fields of geological exploration, coal mining, water conservancy and hydropower, construction of road and railway. We also can design PDC bits according to customer requirements.
