PDC Drill Bit For Sandstone Drilling

1. New Superhard Material;
2. High Drilling Rate;
3. Wearable Blade;
4. Used For Coal Mine

1. Cutting toos adopts superhard material, long service life drill bit;

2. Can be greatly improved the in hard and medium-hard drilling efficiency;

3. Wearable blade, without grinding, convenient to use;

4. Reduce the labor intensity,it is suitable for lithologic strata at level 4-12

This type of bit uses seismic grade tungsten-carbide as the cutting media. Tungsten-carbide does not possess the hardness of diamond and as such has a limited range of application as a core drilling cutting media. Tungsten-carbide bits are however a very cost effective means of drilling softer unconsolidated formations.

PCD(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
