PQ3 Diamond Core Bit are most commonly used bits in mineral exploration and the geotechnical drilling industries. The main crown technical data of impregnated diamond core bits include diamond grade, size, concentrations, matrix hardness and crown shapes. XIZUAN can produce kinds of different bits suitable for many kinds of rocks.
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 penetration and drilling efficiency: Designed for efficient drilling in a variety of geological conditions.
2. Long service life: The hardness and wear resistance of diamond enable it to maintain a long service life even in harsh drilling conditions.
3. Excellent measurement results: The ability to accurately obtain core samples is crucial for geological exploration and engineering surveying.
4. High cost-effectiveness: Although diamond drill bits are relatively expensive, their long life and high efficiency make them highly cost-effective over long-term use.
5. Wide range of applications: Suitable for a wide range of geological conditions, from soft soil to hard rock.
