AI-Powered supplier vetting

SummaryTianfu Tools is a diamond-tool manufacturer established in 2004 and registered in 2009, with stated independent R&D, production, and global sales capabilities. Its scope covers machine tools, diamond tools, hardware tools, electromechanical products, and related import/export activities. Evidence shows 20 years of technical accumulation, eight national patents, four registered trademarks, three production lines, and flexible customization. However, the supplier reports no available SDK, no new products in the past year, no ODM service, no OEM for popular brands, and no supplier-management-system certification. Service procedures exist for corrective actions and complaints, but written records are absent. Export, financial, and customer-case evidence is limited or inconsistent, so several fields remain unverified.

Supplier typeThe supplier is a manufacturer and seller of diamond tools, machine tools, hardware tools, and electromechanical products, with stated R&D, production, and export capabilities. Its history began with diamond-tool manufacturing, and it operates three production lines.

CertificationsThe supplier-management-system certification field is explicitly recorded as NIL. No other certification is identified in the provided slices, although patents and trademarks are reported separately and do not constitute management-system certification.

R&D capabilityThe supplier states it has independent R&D, 20 years of technical accumulation, eight national patents, four registered trademarks, and an R&D focus on materials, structures, and processes. However, it reports no new product in the past year and no available SDK, so innovation strength is evidenced historically but current product-development activity is mixed.

Production capacityThe supplier lists high-temperature sintering, laser cutting, mixing, lathing, punching, sandblasting, and welding equipment, and operates three production lines. It also reports an instruction for finished-product inspection, but no written inspection records are available; capacity scale and production output are therefore only partially demonstrated.

Customization capabilityFlexible customization is explicitly available, and the company description states that it provides customized production and one-stop solutions from design to delivery. In contrast, the supplier reports no ODM service and no OEM service for popular brands, indicating customization capability with restrictions on certain service models.

Product Q&A

Q:Do you support customization?

Yes! We provide full customization including size, material and packaging.

Q:What materials can you drill? Are there different models?

They can be widely used on concrete, reinforced concrete, red brick, granite, marble, etc. We have three types: wet core bits (for water cooling), dry core bits (for water-free environments), and wet & dry dual-use core bits. You can choose the corresponding model for different working conditions.

Q:What material are your drill bits made of? How durable are they?

We use high-grade diamond segments and high-quality blanks. They feature high sharpness and strong wear resistance. Under the same working conditions, their service life is 30%-50% longer than ordinary drill bits, with a lower overall cost.

Q:What is the minimum order quantity?

The minimum order quantity is 1.

Q:What are the payment terms?

We accept T/T and LC.
