Bolt PDC drill bits, diamond drill bit, diamond anchor bit, PDC drill bit type bolt hole diameter connecting thread Note ZTY27 / 2 Φ27 M14 × 1.5 M16 1/2-12 screw M14 × 1.5 used routinely by other thread should specify when ordering ZTY28 / 2 Φ28 ZTY30 / 2 Φ30 ZTY32 / 2 Φ32 high quality alloy bolt drill bit size: ф27-32mm bolt PDC drill bit (normal type) Specifications: ф27-32mm anchor PDC bar bit (enhanced) Specifications: ф27-32mm pdc drill diameter 27-32 (mm) length of 27-32 (mm) common type PDC bolt bit: f <8 soft to medium hard rock; enhanced PDC drill anchor : f <1212's in hard rock; high strength bolt PDC bits: f <18 the integrity of hard rock. 
 Second: diamond / carbide composite sheet (PDC) is in the ultra-high temperature - high pressure conditions, using the static method of sintering fine diamond powder to carbide matrix composite to a super-hard material. In the microscopic state, the diamond layer of diamond grains arranged in the state was disorder between grains connected to each other under certain conditions, bonding, and thus determine its isotropic easy cleavage plane of cleavage with high hardness and strength, so the impact strength, abrasion resistance, and self-sharpening cutting process (to maintain a sustained sharp) outstanding performance, the use of carbide (WC) as the substrate is easy with the impact the characteristics of welding, so it Set diamond with high hardness and high strength carbide in one of the features. Made with PDC PDC drill bit of work to be broken by shearing the rock, than crushed rock or cone bits pregnant diamond head diamond cutting and polishing rocks plow more effective in drilling soft to medium hard formation instead of the traditional drill operations to achieve good economic and production efficiency. 
 Our product is the selection of raw materials through the use of advanced formulations and manufacturing processes, as well as our unique combination of the diamond layer and carbide interface (bonded more firmly and effectively avoid the delamination in use), is the result of a strict quality control system developed out. In western China, eastern, northeastern, extensive use of the Central Plains and other areas with high stability, reliability, in particular, PDC axial and side impact resistance, wear resistance, heat resistance has reached domestic leading level, and won trust of our customers. 
 We will unswervingly follow the path of quality improvement and innovation, product quality and advanced product line for our customers to provide efficient, cost-effective products to achieve the interests of both supply and demand win-win situation. 
 Polycrystalline diamond layer and carbide substrate binding between the tooth structure, the company provides Q series and W series for customers to choose the two tooth can also be specially produced according to customer requirements. 
 Q, W PDC profile series in the sintering process to create a more uniform pressure on the environment, dispersed diamond layer and substrate stress, delamination from the fundamental solution to the problem; lower edge of the residual stress of the composite film has a higher impact strength and wear resistance. 
 Our products by TA formula selected materials, adjusting the formula, improved synthesis methods and techniques and other measures, through a set of advanced and strict quality control system developed out of the new products. Customers in China by the West, East, Northeast, Central Plains and so block the use of feedback, TA series products in ensuring the stability of the original HG, reliability premise, PDC axial and side impact resistance, wear resistance, resistance to significantly improved thermal performance has reached domestic leading level, replacing the original HG products widely adopted by customers. 
 PDC bits, drill in drilling teeth, the early focus of the small, faster drilling bit. Work with the toothed end face drilling by the plane or parts are worn into a flat circular surface, and rock drilling teeth contact area is also increasing, the performance of the drill bit more blunt, drilling bit slower. PDC for the current existence of this problem, we developed a rock breaking can improve efficiency, increase the speed of the bit drilling PDC US formula series. Composite film in the formula to ensure high impact resistance and abrasion resistance, based on the composite film will be showing a clear jagged surface and a high degree of wear and tear since sharp, thereby enhancing the composite film of the "attack."
