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 is designed for coal mining drill bit design, 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 drill and mine PDC PDC drill bit with the use of advanced sintering process, the diamond and carbide at high temperature, high pressure once sintered, has good abrasion resistance, impact resistance and self-sharpening, specifically for the oil / gas drill bit design and manufacture of mining geology, rocks can also be used for other cutting tools. SFD PDC oil drill has SC, EC two series. SC series has a variety of specifications, such as flat teeth and tooth geometry for users to choose. SC proprietary interface design optimizes the combination of diamond layer and carbide substrate, effectively releasing the residual stresses, a 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 the development of a new generation of cutting teeth, can replace imported composite film. Unique monolithic design effectively reduces the residual stress thick diamond layer, enhanced anti-peeling off the side and anti-capacity. Combines the unique interface geometry design, diamond microstructure and properties of thick diamond layer more optimized, EC cutting teeth in complex and harsh environment drilling, can effectively improve the life of the drill bit and downhole drilling speed, overall performance was significantly superior similar products in the market.
