The SW Diamond Casing Shoe is a high-wear-resistant drill bit designed specifically for geological coring and casing drilling. Installed at the bottom of the casing string, it is used to simultaneously open the hole, maintain the casing, and obtain a complete core in overburden or fractured formations.
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. Diamond-Inlaid Cutting Edges: The cutting edges of this drill shoe are inlaid with industrial-grade diamond tips, enabling effective cutting of hard rock formations such as granite and basalt.
2. Wear Resistance: Diamond tips ensure the drill shoe’s durability, maintaining excellent wear resistance even in highly abrasive environments.
3. Casing Protection: This drill shoe helps protect the casing from damage by the drill bit or harsh formations.
4. Improved Core Recovery: SW diamond casing shoes improve core recovery by stabilizing the drill bit and casing, ensuring more intact rock samples are obtained during drilling.
5. Multiple Sizes and Configurations: SW diamond casing shoes are available in a variety of sizes and configurations to meet the needs of different types of drilling equipment and projects.
