De Run Energy Co., Ltd. supplies PDC drill bits engineered for variable geological formations, with cutting structures optimized for enhanced rate of penetration and extended service life. The bits feature high-performance polycrystalline diamond compact cutters and hydraulic designs that improve chip removal and cooling under high-load conditions. These are not generic rotary bits but purpose-built tools for oilfield and geothermal drilling applications.
The cutting elements are made from industrial-grade PDC with tungsten carbide substrates, typically rated for hardness levels of 90-95 HRA. The bit body is forged from alloy steel conforming to API 5CT standards for tensile strength and impact resistance. Standard diameters range from 3.5 inches to 12.25 inches, with custom sizes available on request. The bits are not coated or plated; performance relies on the intrinsic properties of the PDC and the geometry of the cutting profile.
These drill bits are primarily purchased by drilling contractors operating in shale, limestone, and sandstone formations across North America, the Middle East, and Southeast Asia. Buyers typically order in batches of 10 to 50 units, with packaging in steel crates or wooden cases lined with foam. Lead time is confirmed upon order, and Incoterms are negotiable based on destination port and volume. Payment terms are commonly 30% advance, 70% against copy of bill of lading.

De Run Energy Co., Ltd. is registered in Beijing and operates as a technical supplier of downhole drilling tools. The company's profile indicates no verified manufacturing facility details, and no public certifications or client references are listed. Its trust tier is harbor, and response metrics are not available, indicating limited buyer communication history.
The listing confirms no claims about years in business, workforce size, or revenue. The product description focuses solely on technical design attributes of PDC bits, suggesting the company functions as a product-focused distributor or technical agent rather than a full-scale manufacturer. Buyers should request production facility audits or third-party inspection reports before large orders.

Before ordering, verify the PDC cutter grade and bit body material certification. Request material test reports (MTRs) for each batch, especially for tensile strength, impact energy, and hardness. Confirm that the bit geometry matches your formation profile - ask for a cutting structure diagram. Do not rely on supplier claims without third-party documentation. Response rates are low, so pre-order technical validation is critical.
Lead time is not specified and must be confirmed directly. Typical delivery from China takes 30 to 45 days by sea. Incoterms are negotiable, but FOB Qingdao or CIF Rotterdam are common. Payment terms should include a 30% deposit and balance against shipping documents. Avoid 100% upfront payment. Request a packing list and inspection certificate before release of funds. Verify container sealing and moisture protection in transit.
Upon arrival, inspect for physical damage and verify bit diameter and shank thread alignment using calibrated gauges. Test each bit for runout with a dial indicator. Confirm that the PDC cutters are intact and not chipped. Request a batch-specific MTR and hydraulic test report. Retain samples for third-party lab testing if used in critical operations. Documentation should include origin certificates and export declarations for customs clearance.
