The HQ Impregnated Diamond Core Bit is an advanced drilling tool widely used in mineral exploration and geotechnical drilling industries. This bit features a crown with excellent cutting performance, formed by uniformly impregnating high-quality synthetic diamond particles within a metal matrix. It is suitable for core drilling operations from the surface to deep holes.
Below are the main Crown Profiles
 | STANDARDGeneral purpose design, suitable for a wide range of rock formations Great performance of fluid circulation for cooling the bits Customized design for the numbers of waterways easily Available with wider or larger waterway channels |
 | WEDGESuperior flushing capabilityImproved cutting speedSuitable for broken and high abrasive rocks and formationsAvailable with wider or larger waterway channels |
 | TURBOSuitable for high-speed drillingSuitable for competent formations and rocksFree cutting of waterways with greater ejection of fluid and reducing pressure across the bit face because of jetting effect. Available with wider or larger waterway channels |
 | ROUND FACE DISCHARGEDesigned to minimize flushing of core samplesOffers excellent flushing to prevent blockage in waterway channels and minimize flushing of core sample and reduce the undesirable core erosionSuitable for broken or granular formations and rocks |
 | ELONGATED FACE DISCHARGESuitable for broken, sedimentary or metamorphic formations and rocksElongated hole is with better water flushing and more efficient water flow, can prevent bit burnt during drilling due to lack of water |
 | VORTEX PROFILEImprove the drilling efficiencySuitable for soft to medium-hard rocks and formationsAvailable with wider or larger waterway channels |
Matrix Height
 | This refers to the diamond impregnated matrix height.XIZUAN can offer many kinds of core bits with different matrix heights from 6mm-20mm, according to Customers’ requests.Unless otherwise specified, a standard 12mm matrix height is recommended. |
Matrix Hardness
Different hardnesses can be provided according to kinds of rocks to be drilled with different hardness and abrasiveness.
Features
1. High Wear Resistance: HQ impregnated diamond core drills use high-quality diamond grains, possessing extremely high hardness and wear resistance, significantly improving drilling efficiency in hard rock.
2. Excellent Cooling Performance: The drill bit’s rational design effectively dissipates heat generated during drilling, ensuring the drill bit maintains excellent performance even at high temperatures.
3. Rapid Drilling: Thanks to its unique cutting structure and materials, HQ drill bits enable rapid drilling, improving work efficiency and reducing construction time and costs.
4. Multiple Sizes: HQ drill bits are available in various sizes to meet different drilling needs, adapting to various geological conditions and drilling depths.
5. Easy Replacement and Maintenance: The connection design between the drill bit and drill pipe makes replacement and maintenance more convenient, reducing downtime.
Maintenance and Care
1. Operating Procedures: Avoid dry drilling; control drilling pressure and rotation speed to prevent overload that could cause the drill bit to detach or the diamond to break.
2. Flushing System: Keep the flushing fluid clean, ensure unobstructed water flow, and promptly remove rock dust to reduce drill bit wear.
3. Regular Inspections: Monitor drilling speed, torque, and core sample quality during drilling; if any abnormalities are detected, immediately pull out the drill string and inspect the drill bit’s condition.
4. Storage Environment: Store in a dry, well-ventilated place, avoiding moisture and corrosion to extend its service life.
