PDC oil drill special specifications for various models PDC PDC inquire - superhard materials Co., Ltd., Henan SFD! SFD oil / gas PDC drill and mine drill PDC using advanced sintering process, from diamond and carbide at high temperature and high pressure sintering, has good wear resistance, self-sharpening and impact resistance, specifically for the oil / gas and mining geology drill bit design and manufacturing, can also be used for other rock cutting tools. The Quartet amounted to petroleum drill bit with a diamond the composite sheet there are SC, EC two series. SC series has a variety of specifications and other flat teeth and tooth geometries for users to choose. Interface structure design of SC patented-type's optimized the combination of diamond layer and cemented carbide base body's, effectively released the residual stress, from fundamental solution to the stratification problem the composite sheet of; while optimizing of microcosmic the structure of of diamond of make the SC having a than the market on a higher of similar products abrasion resistance. SC composite sheet is widely used in soft to medium hard formation drilling. The Quartet amounted to has been focused on the development of new of cutting teeth in order to satisfy drilling industry complex and changeable of requirements. EC diamond composite sheet is directed geological conditions representing an complex medium hard to the hard formation of got into the the development of of a new generation of cutting teeth, can replace imported composite sheet. Unique overall-style design effectively reduces the the residual Stress Area of ??Thick diamond layer within the's, enhances the anti-spalling and anti-swap edge capability. 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. Quartet of the company in 2001 passed the ISO9001 quality management system certification, the production of each of the products are under strict quality control procedures to ensure that customers receive consistent quality products and attentive service.
