Introduction Synthetic polycrystalline diamond compact(PDC) is composed polycrystalline diamond layer and cemented carbide substrate. It is a kind of super-abrasive product sintered under super-high pressure and at high temperature. With excellent wear-ability, this very hard product has impact toughness. Flat polycrystalline diamond compact Mainly used for making roller cone bit for petroleum drilling and tools for coalmine drilling and geological drilling. Now three kinds of PDC are available: PDC for mining, PDC for coalmine drilling & PDC for oil field drilling. The shape interface can be flat or not. The range of thickness of polycrystalline diamond layer is from 0.8mm to 3mm. And we cut the PDC to different shape as per customer' s requirement. For mining: JF***8, JF***4, JF***8, JF***3, JF***8 For coalmine drilling: JF***4, JF***4 For oil field drilling: JF***8, JF***8, JF***3, JF***8, JF***3, JF***6 Parameter Table Size Diameter(mm) Height(mm) JF***4 *0.3 4.5 JF***8 *0 8 JF***4 *2.5 4.5 JF***4 *3.3 4.5 JF***8 *3.3 8 JF***3 *3.*4 *3.2 JF***8 *6 8 JF***3 *6 *3.2 JF***8 *9.*5 8 JF***3 *9.*5 *3.2 JF***6 *9.*5 *6.*0
