PDC Cutter (1308, 1313, 1613, 1916)
PDC cutters comprise a polycrystalline diamond top layer integrally sintered to a tungsten carbide substrate by using a high-pressure, high-temperature process, and they are vastly applied in drill bits in oil, gas & mining industry.
PDC for oil drilling bits series. Microstructure with complete C-C bond combination is characterized between the grains of the diamond in polycrystalline diamond layer, which allows the high strength, hardness and wearing property of diamond layer. We adopt many types of claw structure of the interface between diamond layer and tungsten carbide substrate, and use the special technological late conditions in order to effectively reduce residual stress of PDC while make the interface combination firmer and more symmetrical. So applied to oil drill bits, PDC displays satisfying thermal stability, higher impact resistance and excellent performance.

Vitrified diamond wheel for pdc cutter grinding
Vitrified diamond wheel for rough Grinding the Cylinder of Polycrystalline Diamond Compacts (PDC cutter). Compared with resin diamond grinding wheel, our vitrified bond wheels lead to 35% grinding cost reduced, 40%grinding time of each PDC saved, and the size precision of PDC improved (from ±0.03mm to ±0.01mm). Vitrified diamond wheels can be used to grind various materials including tungsten carbide, glass, ceramics, fiberglass, plastics, stone and abrasives.

TSP used for gauge protection
Thermally Stable Polycrystalline (TSP) is thermally stable polycrystalline diamond, a versatile material with the hardness of diamond, thermal stability up to 1200°C, and the ability to be manufactured into numerous shapes and sizes. One of the primary applications for TSP is wear protection on the gage of drill bits, but in softer formations, it can be used as a primary cutting element, as well. Because of their performance properties, TSP can also be used in cutting tools, as dressers, as a die material for drawing wire, and for numerous other wear applications. It can be applied on the drill bits for oil and gas industries.
PDC Drill Bits
PDC bit is an integral drill which hasn’t activity components. The structure of PDC bit is very simple, it generally includes drill body, cutting teeth, nozzle and junk slot, etc.PDC bit can be divided into two types: steel body and tungsten carbide matrix. The surface of steel body PDC bit is easily to be eroded. While tungsten carbide matrix PDC bit is difficult to eroded.
In the oil and gas industry, a drill bit is a tool designed to produce a generally cylindrical hole (wellbore) in the earth’s crust by the rotary drilling method for the discovery and extraction of hydrocarbons such as crude oil and natural gas. This type of tool is alternately referred to as a rock bit, or simply a bit. The hole diameter produced by drill bits is quite small, from about 3.5 inches (8.9 cm) to 30 inches (76 cm), compared to the depth of the hole, which can range from 1,000 feet (300 m) to more than 30,000 feet (9,100 m). Subsurface formations are broken apart mechanically by cutting elements of the bit by scraping, grinding or localized compressive fracturing. The cuttings produced by the bit are most typically removed from the wellbore and continuously returned to the surface by the method of direct circulation.
Self sharpening of PDC tooth is very good. Polycrystalline diamond grains shed in the process of cutting the rock and form new blade grain to update the selfsharpening. In addition, tungsten carbide substrate forming sharp cutting edge after wearing, exhibiting good anti-impact performance and providing flexibility for diamond.
