PDC- Polycrystalline diamond compact is composed of polycrystalline diamond layer and tungsten carbide substrate, the polycrystalline diamond layer possesses extremely high hardness and abrasion resistance whereas the tungsten carbide substrate would greatly improve the malleability and weld ability of the whole composite, the polycrystalline diamond compost is used oil well drilling petroleum, geology exploring, coalfield mining and mechanical industry.
Polycrystalline diamond compost (PDC) cutter inserts for drilling suitable for soft to hard geological terrane according to customers' demand we can offer polycrystalline diamond compact with claw structures and chamfer types whether or not grinding and polishing.
Polycrystalline diamond compact (PDC) cutter inserts for tools is suitable alloy non-metal and metal with high rigidity. According to the customers' demand, we can offer different shapes PDC cutters, such as flat face, convex face, helmet face, ridge face, half cut type is avalible. The height of diamond layer is different for different application.
PDC cutters for geological mining field drilling bits series are designed for markets in the pursuing of cost. This series PDC are mainly used for producing anchor-shank drill bits, which are equipped with sharp edge, fast footage, high effectiveness, stability, economical and practical advantages.

Large cutters(16-19mm) are more aggressive than small cutters(8-13mm). However, they may increase torque fluctuations. For production, small cutters are easy to make excellent quality, but large cutters may not, there are many factors to influence the quality.
Smaller cutters (8mm, 10mm, 13mm) are very sharp, have been shown to drill at higher ROP than large cutters in certain applications. One exampled application is limestone. Also, bit design employing smaller cutters have a higher cutter density to enable them to withstand higher impact loading.
Additionally, small cutters produce smaller cuttings while large cutters produce larger cuttings. Large cuttings may cause problems with hole cleaning if the drilling fluid cannot carry the cuttings up the annulus.
Generally speaking, we have consistant quality no matter for small cutters or large cutters, especially for large cutters, our 16mm can be competed with E6 quality, and 19mm cutters can be compared with USS quality.
