PDC cutter

PDC cutters (Polycrystalline Diamond Composite) is consist of polycrystalline Diamond layer sintered with tungsten carbide substrate under ultra-high temperature and pressure, he PDC cutter like 1308,1313 etc, PDC cutters are widely used in petroleum/oil field PDC bit, eological PDC exploration bits, gas exploration bits, CD/PDC coal mining drill bits, ilfield drilling bits ,currently, we developed new type of PDC cutters, the length of the cutter is 32mm, with a round radius of the tungsten carbide substrate of the PDC cutter.

PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.

Microstructure with complete C-C bond combination is characterized between the grains of diamond in polycrystalline diamond layer, which allows the high strength, high hardness and high wearing property of Diamond layer as well as good self-sharpening property. New cutting surfaces will appear during the course of abrasion, which keeps effective cutting rocks.

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.

The serrate structure combination between polycrystalline Diamond layer and hard alloy substrate allows more fixed combination between the two layers and allows more impact resistance of the whole PDC.
