(KG) 36/40 GREAT PDC bit Advantage   Equipped for Performance Great PDC Bits are equipped with 1.High Abrasion tungsten carbide material, Hardened Alloy Steel base material 2.High performance PDC-Cutters 3.Carbide and Diamond gauge protection 4.Carbide/Diamond Shock Studs 5.Threaded or Plain Carbide Nozzles for Flushing

Steel Body PDC Use high-quality steel to make the base material of PDC bit, the surface of the blade weld high-performance wear-resistant materials, the use of computer software for the overall design of three-dimensional PDC BIT, double asymmetric teeth straight blade, medium parabolic crown, long Gage shape structure. Cutting structure using force balance design, unique PDC cutter layout and positioning of the PDC bit to keep a sharp cutting edge in drilling, effectively improve the offensive PDC BIT and drilling speed. The application of fluid dynamics analysis and numerical simulation of hydraulic flow field analysis technology to design, help to improve chip speed drill and anti-balling capacity. Suitable for high compressive strength, with abrasive medium hard to hard formations, such as shale, limestone, anhydrite, sandstone and so on.

What is the feature of 17 1/2tricone drill bit? 1.The strength and wear resistance of inserts are improve by using carbide inserts with high strengthand high wear resistance. 2.Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the load capacity and service life of the bearing. 3.The service life of the bearing is further extended by adopting harder and mort wear resistant material for thrust bearing. 4. Preventing reflux structure has dual function, it can avoid air counterflow and dust entering into bearing when the air-compressor stop working accidentally, and separate air and water in order to avoid water entering into bearing when it works normally to prolong the life of bearing 5.This series oil well rock bit use Sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased. 6.Thrust bearing surfaces are hardfaced and treated with friction reducing technology. 7.This series oil well rock bit use Journal bearing. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improved. What is the superiority of 17 1/2tricone drill bit? 1. It can recycle; it just consume one third of its lifespan in oil exploration process. 2. It can withstand high wob under the conventional drilling rate.
