| 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. |

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.. |

| 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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
