The Drill Kelly offered by De Run Energy Co., Ltd. is a square and hexagonal tool designed for rotary‑table drilling rigs. It is supplied in a full size range from 2.5" to 6" and is forged from AISI 4145H alloy steel. Production follows API SPEC 7‑1 and the Chinese SY/T6509‑2000 standard, ensuring compatibility with common wellhead configurations. The product description highlights both the square and hexagonal profiles, catering to different chuck assemblies.
AISI 4145H provides a balance of tensile strength and wear resistance that is typical for drilling‑head components. In the industry, similar Kellys are often heat‑treated to a hardness of 30‑35 HRC and finished with a mill or black‑oxide coating to improve corrosion resistance. Standard dimensional tolerances for this class of tool are ±0.02 inches, which supports reliable alignment in high‑torque applications. These attributes make the Kelly suitable for prolonged field use under variable load conditions.
Primary users are oilfield service companies and drilling contractors that require robust torque transmission for deep‑well operations. While the listing does not disclose a minimum order quantity, payment terms or lead‑time, interested buyers should request these details directly from the supplier. Confirmation of incoterms, packaging specifications and any required certifications will help streamline the sourcing process.

Before placing an order, confirm that the Kelly complies with API SPEC 7‑1 and SY/T6509‑2000 by requesting the relevant certificates and a recent mill test report. Verify the material grade, heat‑treatment records and any surface‑coating specifications to ensure they meet your project requirements. These documents form the basis for quality acceptance and contractual compliance.
Discuss logistics early by agreeing on incoterms such as FOB Shanghai or CIF Ningbo, and ask the supplier for the expected lead time, which typically ranges from four to six weeks for standard sizes. Clarify payment terms, commonly TT in advance or an L/C at sight, and ensure that the supplier can provide export documentation required by Chinese customs and your destination port.
Arrange a third‑party inspection at the factory or upon arrival to verify dimensions, hardness and surface finish against the supplied specifications. Request a detailed inspection report, including any non‑destructive testing results, before releasing payment. Maintaining clear documentation of these checks will help mitigate risk and ensure the delivered Kelly meets the agreed standards.
