FAQ

PDC bits are mainly suitable for soft to medium-hard formations such as mudstone, sandstone, and limestone. For extremely hard and highly abrasive formations such as granite and quartzite, impregnated diamond bits or tricone bits are recommended. Correct formation-bit matching is the key to improving ROP. You can provide geological condition information, and we will recommend the most suitable bit model for you.

PDC bits break rock by shearing, with fast ROP and long life, but are mainly suitable for soft to medium-hard formations; tricone bits break rock by impact and crushing, suitable for harder formations, but with relatively slower ROP. In practical applications, PDC bits have gradually become the preferred tool in oil drilling, mining, and other fields due to their high efficiency and long life.

Yes. We provide comprehensive OEM/ODM customization services, including bit type, material, shape, specification, packaging, and brand identification. The minimum order quantity is flexible, depending on product type and customization degree. Standard products generally have a low MOQ. Welcome to visit our OEM Customization page to submit your requirements, and we will reply within 24 hours.

Standard products are generally completed and shipped within 5-15 days. Non-standard customized products depend on design complexity and production schedule, usually 15-30 days. We cooperate with many international logistics companies to provide sea freight, air freight, and other transportation methods to ensure safe and timely delivery.

We have a professional team of technical engineers providing full-cycle technical support from selection consultation, on-site guidance to post-drilling analysis, including: bit selection recommendation, drilling parameter optimization guidance, operation training, bit wear analysis and improvement suggestions, etc. No matter which country you are in, you can get timely technical support via email, phone, or online video.

The main criteria include: 1) obvious decline in ROP (usually more than 30%); 2) abnormal vibration or noise; 3) finer or less cuttings; 4) smaller hole diameter. It is recommended to regularly check bit wear. Once large-scale cutter loss or severe wear is found, the bit should be replaced in time to avoid damaging drilling tools or affecting hole quality.

The service life of PDC drill bits varies depending on geological conditions, drilling parameters, and operation level. In ideal soft to medium-hard formations, a high-quality PDC bit can drill hundreds or even thousands of meters. In hard rock and highly abrasive formations, the life will be relatively shorter. Hongyue Drill's PDC bits use high-quality cutters and advanced brazing processes to ensure excellent durability and consistency.

We support various international trade payment methods such as T/T telegraphic transfer and L/C letter of credit. Usually new customers use 30% deposit + 70% before shipment T/T for the first order. Long-term cooperative customers can enjoy more flexible payment terms based on cooperation scale and credit. Specific payment methods can be negotiated during order discussion.

We provide factory inspection reports for all products, including key indicators such as dimensional accuracy, welding strength, and wear resistance. At the same time, we have passed ISO quality management system certification and own more than 20 patents. You can request sample testing or arrange third-party inspection at our factory. We will also provide actual use cases and customer feedback references according to customer needs.

Our products have been exported to more than 50 countries and regions including Saudi Arabia, Russia, Brazil, Nigeria, India, and Australia. Proven under various complex geological conditions worldwide, our products are stable and reliable. We are familiar with import and export procedures and standards of various countries and can provide export documents and logistics support for customers.
