Coal Mining Pdc Diamond Non-coring Drill Bit
These PDC diamond non-coring drill bits are engineered for hard coal seam penetration using a sintered matrix with high-grade diamond particles and reinforced carbide substrates. The design eliminates core extraction, focusing instead on rapid, continuous hole advancement in abrasive coal strata. The bit body integrates optimized fluid channels to manage cuttings and cooling under high rotational loads.
The diamond powder used is selected for uniform size distribution and high fracture toughness, with improved sintering techniques enhancing bond strength between grains and the metal matrix. Carbide inserts are welded using advanced induction methods to increase joint integrity under shock loads. The internal cavity structure is balanced for even pressure and temperature distribution, reducing thermal cracking and extending bit life. These are standard features in modern PDC non-coring bits for coal mining, but the supplier claims specific enhancements in matrix composition.
The bits are used by coal exploration teams in China, Australia, and Eastern Europe for geological surveying and seam mapping. Buyers typically order in batches of 10 to 50 units for field testing. Trade terms are negotiated directly; lead times are not specified. Payment is commonly via T/T or L/C. Minimum order quantity is not stated and must be confirmed with the supplier. The product is not designed for core recovery and is not interchangeable with coring bits.
| Bit Type | PDC diamond non-coring, roller cone alternative |
| Diamond Grade | High-purity industrial diamond powder (typical size range: 40/60 to 60/80 mesh) |
| Matrix Composition | Sintered tungsten carbide with cobalt binder (typical Co content: 6% to 10%) |
| Carbide Substrate | New-type tungsten carbide with improved fracture toughness (exact alloy not specified) |
| Weld Strength | Enhanced via induction welding (typical shear strength: >350 MPa for carbide-to-bit body) |
| Diameter Range | Typical range: 76 mm to 152 mm (standard for coal exploration drilling) |
| Length | Standard length: 1.2 m to 1.8 m (dependent on diameter) |
| Cutting Structure | Diamond-impregnated matrix with no replaceable inserts (non-coring design) |
| Cooling Channels | Internal spiral or radial fluid paths (typical flow rate: 30 to 50 L/min for optimal cuttings removal) |
| Operating Pressure | Recommended: 10 to 25 bar (typical for coal seam drilling) |
Shandong Yikuang Drilling Technology Co., Ltd. is located in Linqing, Shandong Province, China, a region with established drilling equipment manufacturing. The company’s address is listed on public trade directories, and its profile indicates specialization in drill bit technology. No information is provided on years of operation, workforce size, or production volume. No certifications, client names, or test reports are disclosed.
The supplier focuses on PDC drill bit design improvements, particularly in diamond bonding and carbide welding. Their claims center on process enhancements rather than standardized product lines. Response metrics show no recorded response rate or average response time, suggesting limited customer support. Buyers should treat this as a technical manufacturer requiring direct technical validation before procurement.

Sourcing Coal Mining Pdc Diamond Non-coring Drill Bit from Shandong Yikuang Drilling Technology Co., Ltd. - China Import Guide
Before ordering, verify the diamond grade, matrix composition, and carbide alloy with material certificates or lab reports. Request a sample bit for destructive testing to confirm internal structure and weld integrity. Confirm that the bit is truly non-coring and not a hybrid design. Ensure the supplier can provide batch traceability and consistent performance across multiple orders.
Lead time is not specified but typically ranges from 3 to 6 weeks for custom sizes. Incoterms are not listed; negotiate FOB Qingdao or CIF destination. Payment terms are commonly 50% advance and 50% against bill of lading. Confirm packaging: bits should be individually wrapped in foam and packed in steel crates to prevent damage. No export documentation is mentioned, so request commercial invoice, packing list, and origin certificate in English.
Upon arrival, inspect each bit for surface cracks, uneven diamond exposure, or loose welds. Use a dial indicator to check axial runout. Perform a dry spin test to detect imbalance. Retain one bit as a reference sample. No certification is provided, so buyers must rely on physical inspection and supplier reputation. Document any defects immediately and request replacement before installation.
