What is the difference between bread PDC and flat PDC pieces?

Bread PDC pieces have a raised center and thicker diamond layer, offering superior wear resistance and impact strength, making them better for complex formations like rubble. Flat PDC pieces offer faster penetration speed in ordinary formations but have lower wear resistance.

How should I choose the right PDC composite piece?

Selection should be based on the features of the formation you need to drill. You should combine the advantages of different PDC types to choose the piece that best suits your specific geological strata.

AI-Powered supplier vetting

SummaryThe supplier operates in metal tool, drilling equipment, mining machinery, mechanical equipment, and related metal-product businesses. It reports ISO9001:2015 and ISO14001 certifications, as well as additional management-system certifications including BSCI, TS16949, and GMP, although the applicable scope and validity are not specified. Service procedures, corrective-action procedures, and complaint-handling records are stated to exist. The supplier offers OEM and ODM services and launched new products during the past year, but it has no available SDK and only two R&D engineers are reported. Production information includes five production lines and 31–40 quality-control staff; the stated output figure is omitted for privacy. Financial records are identified for 2021–2023, but no financial results are provided. No Fortune 500 cooperation is reported, and overseas-service coverage is listed as zero.

Supplier typeThe supplier is a manufacturer and seller of metal tools, drilling and oil-production equipment, mining machinery, mechanical parts, hardware, and metal materials. Its product description specifically covers drill bits for water wells, natural gas, oil, coal, geothermal, and geological exploration applications.

CertificationsThe supplier reports ISO9001:2015 and ISO14001 certifications, while another slice lists BSCI, TS16949, ISO9001, and GMP management-system certifications. The records do not specify certificate scope, issuing bodies, or validity dates, but they explicitly evidence multiple certifications.

After-Sales capabilityThe supplier states that it has written procedures and implementation records for service capability assessment, corrective and preventive actions, and customer complaint handling. However, overseas-service coverage is recorded as zero, so the evidence supports formal service processes but not broad international service reach.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has R&D engineers with 6–10 years of total experience. It also reports only two R&D engineers and explicitly states that no SDK is available, indicating some product-development capability but limited evidence of broader technical resources.

Production capacityThe supplier reports five production lines and 31–40 quality-control staff, providing explicit evidence of an organized manufacturing and quality-control setup. The supplier also states an annual production-output range, but that figure is excluded here under the privacy requirement; product-specific capacity is not provided.

Customization capabilityThe supplier explicitly offers ODM and OEM services and provides different drill-bit models and sizes for varied applications and rock conditions. This supports customization capability for relevant products, although the scope of engineering changes and customization limits is not detailed.

Client casesThe supplier explicitly reports no cooperation with Fortune 500 companies. Although it states a preference for repeat buyers at 80%–100%, no named customers, reference projects, or verifiable customer cases are provided.
