Description

Description of Diamond coated inserts PDC inserts 1. PDC cutters are sintered with selected diamond powder and tingsten carbide compact under high temperature and ultra high pressure. 2. The PDC cutters have high hardness, high abrasion resistance and high impact resistance. 3. PDC bttons bits can be widely used for oil and gas well drill bits, geological drill and mining drill bits. The PDC cutters can also be used as cutting tools with diamond for cutting, griding and polishing. Application of PDC cutters: PDC cutters are widely used for petroleum and oil field PDC bit, geological PDC exploration bits, gas exploration bits, PDC coal mining drill bits. PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum. Advantages of PDC cutters: 1.New cutting surfaces will appear during the course of abrasion, which keeps effective cutting rocks 2.high strength, high hardness and high wearing property of diamond layer as well as good self-sharpening 3.PDC drilling bit made of such PDC will break up rocks depending on shearing action when it works, which is more effective than crushing of rocks by roller cone bit or plowing and grinding of rocks by diamond impregnated bit 4.The serrate structure combination between polycrystalline diamond layer and hard alloy substrate allows more fixed combination between the two layers and more impact resistance of the whole PDC. The specifications of PDC cutter for oil drilling bits:
