A Brief Discussion of the Advantages of Diamond Drill Bits
Polycrystalline diamond compact (PDC) is a special ultra-hard material synthesized in a single process from synthetic diamond and cemented carbide under high temperature and high pressure. It combines the key strengths of both materials: the exceptional hardness and wear resistance of diamond, and the strong impact resistance and good edge exposure of cemented carbide. Drill bits built with this cutting structure can greatly improve operating efficiency, making them an ideal choice for drilling in medium-hard to hard formations. They are widely used across coal mining, oil drilling, water conservancy and hydropower projects, railway and highway construction, and tunnel excavation.
The diamond drill bits produced by our company use high-quality 42CrMo steel bodies formed by forging, then processed with fully automated vacuum heat treatment. This significantly improves the mechanical properties of the bit body and provides solid assurance for overall bit stability. To match different formation requirements, the products are divided into multiple series, with the following advantages:
Standard two-wing PDC anchor bit (standard / half-cutter standard type)
The blades are made with high-quality domestic PDC cutters and are suitable for formations up to grade 8. Under comparable rock conditions, service life can reach 10–30 times that of conventional carbide bits, and operating efficiency improves by at least 60%. In addition, no regrinding is required, which reduces labor intensity and saves considerable working time.Reinforced two-wing PDC anchor bit (standard / half-cutter reinforced type)
The blade core material uses products from GE (USA). Diamond content is 50% higher than that of conventional bits, providing substantially improved wear resistance. While boosting drilling efficiency, it also lowers overall construction cost, and is suitable for medium-hard formations up to grade 12.High-strength diamond drill bit
The blades use newly developed spherical diamond cutters, offering high penetration rate and strong impact resistance. During drilling, the lip edge enables stable scraping in uniform formations, while the protruding structure helps suppress sudden over-penetration when encountering rock fractures. This reduces the risk of accidental bit damage and improves adaptability in complex formations.
