PDC cutters
PDC cutters (Polycrystalline diamond compact) is consist of polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high temperature and pressure,the PDC cutter like 1308,1313 etc, PDC cutters are widely used in petroleum/oil well field PDC bit,geological PDC exploration bits, gas exploration bits,PCD/PDC coal mining drilling applications.

PDC cutters for oil well field
This series of PDC cutter is high performance PDC cutters (PCD inserts) designed for PDC oilfield drilling bits . The performance index and stability of this cutter is better than that of normal production available in the market, after all kinds of strictly workshop tests and oil field drilling tests. Now the PDC cutters are test well in oil field drilling bits among foreign countries and areas.

The PDC cutter features longer life - Employing new sinter technics firms the bonding of diamond

particles. The abrasion resistance has a vast increase, with 2 mm of diamond layer,this assure the diamond compact cutter has a longer life .Higher impact resistance - The beveled interface of diamond layer and tungsten carbide, with radially shallow slots on it, reduces residual stress of PDC diamond compact cutter, and increase impact resistance.Thermal stability - The resist temperature of NPF series reaches 700℃ , which makes reliable quality and better performance when the PDC used in the drill bits..

The oil welll bits use PDC cutters is based on adoption of a series of new technology and high quality raw materials, impact resistance and thermal stability of NPF Series improve a lot, and rate of penetration increases while drilling hard rock. NPF Series PDC have achieved outstanding drilling performance and is highly estimated by customers.
Higher grade and purer diamond powder for the PDC cutter, in which impurity content decreases vastly, is chosen as raw material to increase bonding strength among diamond.Grit mixture ratio of diamond powder and sintering technics are improved which increase rate of penetration while drilling in hard rock.Shallow slots in length and breadth distribute homogeneously on the top of tungsten carbide substrate. This kind of interface improves stress distribution and raises impact resistance and reliability.Thermal stability reaches 750℃.Improved structure of sintering cavity makes that temperature and press distribute homogeneously during the sintering process, and assures stable performance of PDC cutters.

PDC cutters for Coal mining
This kind of PDC cutter is designed for shallow stratum drilling specially, which is economical and drable. Non-planar interface reduces residual stress and PDC diamond layer with thickness of 1mm to 1.5mm which is thicker than normal PDC cutters,increases abrasion resistance of PDC cutter. Since it was put in the market, this type PDC cutter has been widely recognized by customers because of reliable quality and cost performance.
Our coal mining use PDC cutter is specially designed for coal mining, which is mainly used to make anchor-shank drill bits. It is economical and durable, having high rate of penetration and great efficiency.This kind of cutter is designed for shallow stratum drilling. Compared with normal PDC cutters,he abrasion resistance has an increase of 30%. At the same time, the interface of shallow slots, which are symmetrical and radial, improves distribution of stress and increases reliability and life of PDC cutter.
