Polycrystalline Diamond Compact PDC Core Drill Bits for High Speed Drilling

Polycrystalline Diamond Compact PDC Core Drill Bits for High Speed Drilling

Description of Goods

Theory

PDC(TSP) core bits are similar to surface-set diamond bits in that they are set with a single layer of cutters mounted on the face of the bit in a pre-determined pattern. Instead of natural drill diamond however, the cutting media used on geotechnical bits are synthetic polycrystalline diamond elements. These elements are composed of micron-sized particles of synthetic diamond that have been formed into various geometric shapes.

Like surface-set diamond bits, geotechnical bit crowns consist of a tough wear resistant matrix body that as a minimum includes natural diamond gauge protection setting. In most cases, the gauge protection setting is augmented with seismic grade tungsten-carbide pads and/or polycrystalline diamond elements.

Shear is the mechanism by which geotechnical bits cut the formation being drilled. In softer formations, these bits are capable of very high rates of penetration when compared to surface-set diamond bits due largely to their high degree of cutter exposure.

TSP Core Bits are ideal for geotechnical drilling applications. They are suited for soft to medium hard formations, such as clay, shale, sandstone, limestone, marble, basalt, etc

Introduction of PDC (Polycrystalline Diamond Compact)

PDC is made of diamond micro-powder and hard alloy substrate under high temperature and high pressure. It possess of high wear resistance like diamond, at the same time the impact resistance like hard alloy and that’s made it the best material as a drill bit cutter. Reinforced PDC has higher dense diamond powder, claw hard alloy substrate made the two layers solid as whole one. So, the reinforced PDC of supper wear resistance, longer service life and high efficiency.

Suitable for soft to medium mations(f=1-10), particularly suitable for harder rock construction, not available in broken, fractured, strong abrasive formations.

>The bit body are adopted advanced sintering technology, have high strength and good gauge protection;

>High quality polycrystalline diamond compact (PDC) cutters as the cutting teeth and advanced welding technology make the bits have stable quality.

>The bits have strong stratum applicability, high drilling efficiency and long life. The various performance are much better than steel body PDC bits.

Our Product Features

1) With feature of high working efficiency, smooth surface
2) Advanced technics and strict process control
4) Long lifespan and stable performance
5) Competitive price and superior quality
6) Excellent service

Advantages

1. Many years of experience combined with recent improvements in technology and manufacturing concepts have resulted in greatly improved drilling performance of impregnated PQ HQ NQ BQ diamond core bits.
2. High quality synthetic diamond powders are distributed in the depth of impregnated diamond core bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond.
3. The matrix of our impregnated diamond core bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action.
4. Our impregnated diamond core bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.

• High quality drilling equipment;
