SFD oil / gas drill and coal / mining drill composite sheet, also known as polycrystalline diamond compact, high strength, hardness, wear resistance, impact resistance and good self-sharpening, the products quality has close to the world's most advanced high-end products, mainly used in oil and gas exploration, geological drilling and other fields. (A full range of PDC cutters designed for oil / gas drilling and mining bits, are manufactured under state-of-the-art sintering processes. PDC cutter combines the hardness and abrasion resistance of diamond with the impact resistance of tungsten carbide, and provides faster, more durable and more cost-effective drilling.) MT series designed specifically for the coal mining drill, its superior price by domestic and foreign customers a wide range of ages. MT cutter has built a good reputation for mining application by offering best cost performance. SFD oil / gas PDC drill and mine drill PDC using advanced sintering process, from diamond and tungsten carbide under high temperature, high pressure once sintering, has good abrasion resistance, impact resistance and self-sharpening, specifically for the oil / gas and mining geology drill bit design and manufacturing, can also be used for other rock cutting tools. SFD PDC drill oil there SC, EC two series. SC series has a variety of specifications and other flat teeth and tooth geometries for users to choose. SC proprietary interface design optimizes the combination of the diamond layer and the cemented carbide substrate, effectively releasing the residual stress from the fundamental solution to the problem of delamination of the composite sheet; while optimizing the microstructure of the SC than diamond market similar products on a higher wear resistance. SC composite sheet is widely used in soft to medium hard formation drilling. SFD has focused on the development of new cutting teeth in order to meet the complex requirements of the drilling industry. EC PDC is more complex geological conditions for medium hard to hard formation drilling develop a new generation of cutting teeth, can replace imported composite sheet. Unique monolithic design effectively reduces the residual stress thick diamond layer, enhanced anti-peeling off the edge and anti-capacity. Combines the unique interface geometric design, diamond micro-structure and other characteristics of the diamond layer thickened more optimized, EC cutting teeth in the complex and harsh environment drilling, can effectively improve bit life and downhole drilling speed, overall performance was excellent similar products in the market.
