It offers broad customization and ODM services, but reported no new products in the past year and has no SDK. Key operational gaps include no valid manufacturing contract with affiliated subcontractors, no outsourcing SOP, no ongoing production-volume reconciliation, and no overseas warehouse, showroom, agents, or branches. No certification, financial performance, or customer-case evidence is provided.

Supplier typeThe supplier is identified as a Manufacturer/Factory and a limited company, operating in Wuxi, Jiangsu, China. Its stated business scope includes manufacturing specialized geological exploration equipment and instruments, as well as metal-related products.

After-Sales capabilityThe supplier has documented procedures and records for corrective/preventive actions and customer complaints, supporting an established service-response process. However, it has no overseas warehouse, showroom, agents, or branches, and reports services in zero overseas countries, limiting demonstrated overseas after-sales infrastructure.

Production capacityThe supplier reports seven production lines and in-stock capacity, indicating established manufacturing resources. Nevertheless, it lacks a valid contract with affiliated subcontractors, has no outsourcing SOP, and does not continuously reconcile production quantities for each batch or lot, creating documented production-control weaknesses.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad customization capability.

Product Q&A

Q:Can surface-set diamond core bits be used for drilling in ultrahard rock formations?

Surface-set diamond core bits can handle hard rock formations, but ultrahard formations like diamond-bearing kimberlites may require specialized diamond bits.

Q:What is the typical weight of surface-set diamond core bits?

The weight of surface-set diamond core bits varies depending on the bit size, ranging from a few kilograms to several hundred kilograms.

Q:Can surface-set diamond core bits be used for drilling in iron ore deposits?

Yes, surface-set diamond core bits can be used for drilling in iron ore deposits, provided the rock hardness and other drilling conditions are considered.

Q:Are surface-set diamond core bits suitable for drilling in fractured granite?

Yes, surface-set diamond core bits can be used for drilling in fractured granite, but precautions must be taken to prevent diamond loss due to the presence of fractures.

Q:What is the recommended drilling fluid for use with surface-set diamond core bits?

The recommended drilling fluid is water-based mud or drilling mud that provides lubrication, cooling, and effective cuttings removal.
