1.Product Overview
The diamond impregnated drill bit is a highly efficient and advanced rock drilling tool that utilizes diamond as the abrasive material. Unlike surface-set bits with large, exposed diamonds, the impregnated bit employs a more complex and efficient technology.
Structure & Working Principle:
Structure:The bit consists of a steel body (black section) and a matrix (silver serrated crown section).
Steel Body:Provides structural support and connection to the drill string.
Matrix (Working Layer):A metal-based composite sintered from various metal powders (e.g., tungsten, cobalt, copper). Synthetic diamond microparticles are uniformly impregnated throughout the matrix rather than being surface-set.
Working Principle (Self-Sharpening Effect):During drilling, the matrix gradually wears away due to friction with the rock. This continuous wear exposes fresh, sharp diamond particles,maintaining an efficient cutting surface while shedding dulled grains. This self-sharpening mechanism ensures sustained performance and extended service life.
2.Key Features & Advantages
Exceptional Wear Resistance & Long Service Life:The diamond-impregnated matrix provides a thick, durable working layer, significantly outperforming surface-set bits in longevity.
High Penetration Rate:The self-sharpening effect ensures consistent drilling efficiency, particularly in medium-hard to extremely hard formations.
Smooth Operation & High-Quality Coring:Designed for core drilling, the bit enables stable cutting action, facilitating the recovery of intact, high-quality core samples.
Customizable Adaptability:By adjusting the matrix composition (hardness/wear resistance) and diamond concentration, the bit can be tailored for formations ranging from soft to extremely hard rock.
3.Technical Parameters (Estimated)
Type:Diamond Core Bit
Outer Diameter:Designed for optimal core recovery, standard diameters range from 3.5 to 12.25 inches.
Cooling Channel Design:Impacts heat dissipation efficiency; minimum waterway width of 5.5mm enhances thermal shock rock-breaking effectiveness.
Diamond Concentration:Customized based on formation abrasiveness and hardness.
