Mining Drilling BQ NQ HQ PQ Impregnated Bits Diamond Core Brill Bit for Hard Rock Core Recovery

Product Description:

Features:

Impregnated diamond core bits have several distinctive features that make them highly effective for drilling in various rock formations. Here are some key features of impregnated diamond core bits:

• Versatility: Impregnated diamond core bits are versatile and can be used for drilling in a wide range of rock formations, including hard, abrasive, and consolidated formations. They are suitable for applications in mining, geotechnical exploration, construction, and other industries.
• Diamond Impregnation: The diamonds in impregnated diamond core bits are uniformly distributed and embedded throughout the metal matrix. This impregnation allows for continuous cutting action and ensures consistent performance throughout the lifespan of the bit.
• Cutting Efficiency: Impregnated diamond core bits offer high cutting efficiency due to the presence of numerous diamonds embedded in the matrix. The diamonds grind or shear the rock formation, resulting in faster penetration rates and increased drilling speed.
• Longevity and Durability: Impregnated diamond core bits are known for their durability and extended lifespan. The synthetic diamonds embedded in the metal matrix provide excellent abrasion resistance, allowing the bit to maintain its cutting performance over prolonged drilling operations.

In addition to these features, impregnated diamond core bits boast several other benefits, such as high core recovery, customization to suit specific drilling requirements, a waterway design for effective cooling and flushing, and various thread options for easy integration. They also offer cost-effectiveness in the long run, reducing the need for frequent bit replacements.

Technical Parameters:

Bit Diameter: The bit diameter refers to the outer diameter of the core bit. It is usually measured in millimeters (mm) or inches (in) and determines the size of the core sample that can be extracted.

Diamond Size and Concentration: The size of the synthetic diamonds embedded in the metal matrix can vary. Smaller diamond sizes are often used for harder rock formations, while larger diamonds may be suitable for softer formations. The diamond concentration refers to the amount of diamonds in the matrix, typically expressed as carats per meter or carats per foot.

Matrix Type: The metal matrix of impregnated diamond core bits can be made of various materials, such as tungsten carbide or other hard alloys. The matrix type affects the overall strength, toughness, and wear resistance of the bit.

Matrix Hardness: The hardness of the metal matrix is an important parameter to consider. It should be optimized to provide a balance between diamond retention and cutting efficiency. The hardness is typically measured on the Rockwell scale or the Vickers scale.

Waterways: Impregnated diamond core bits feature waterways or flushing holes that allow the passage of drilling fluid or water to cool and lubricate the bit during drilling. The number, size, and arrangement of waterways can impact the drilling performance and the effectiveness of debris removal.

Core Recovery: Core recovery refers to the percentage of the intact core sample that is successfully extracted from the rock formation. Impregnated diamond core bits are known for their high core recovery rates, which are influenced by factors such as cutting mechanism, diamond quality, and bit design.

Thread Connection: Impregnated diamond core bits are commonly designed with threaded connections that allow them to be attached to the drill string. The thread type and size should match the drilling equipment being used.

Drilling Speed and Feed Rate: The drilling speed and feed rate are critical parameters that depend on the rock formation, diamond quality, and drilling equipment. Finding the optimal balance between drilling speed and feed rate ensures efficient cutting and prolongs the bit's lifespan.

Applications:

Impregnated diamond core bits are widely used for many different purposes across various industries. Their versatility and precision make them ideal for drilling and sampling operations, such as Mining Exploration, Geotechnical Engineering, Geological Surveys, Environmental Studies, Construction and Civil Engineering, Oil and Gas Exploration, and Research and Laboratory Analysis.

In mining exploration projects, these bits are employed to gather geological information from mineral deposits. They can also be used to collect core samples from sites undergoing geotechnical engineering and environmental studies, to assess the strength and stability of the soil and the extent of pollutants.

During geological surveys, impregnated diamond core bits are used to examine rock formations and fossil records. For oil and gas exploration, they can be used to obtain core samples from potential reservoirs to determine the hydrocarbon content of the rock formations. Finally, in research and laboratory settings, the samples obtained with these bits can be studied for various mineralogical and geochemical properties.

It is important to take into account the various conditions and requirements of each specific application when using impregnated diamond core bits. In any case, these tools provide invaluable insights for multiple industries.
