Import Bit Type And Well Drilling Use Pdc Drag Bit — Buy in wholesale FOB from Supplier in China

The PDC drag bit from Linqing City Ruilong Drill Co., Ltd. is designed for hard rock and sedimentary formations in water well and geothermal drilling applications. It features polycrystalline diamond compact cutters bonded to a steel body, with cutter sizes typically ranging from 8mm to 14mm in diameter. The bit body is manufactured using high-strength alloy steel with a wear-resistant profile, and the cutting structure follows a helical or spiral layout to optimize chip removal. Exact dimensions and cutter count are determined by the target borehole diameter and formation hardness, as specified by the buyer.

These bits are built for use in formations ranging from medium-hard shale to dense limestone. The PDC cutters are sintered from synthetic diamond grit under high pressure and temperature, offering consistent wear resistance. Standard cutter grades include 508, 608, and 708, which denote diamond concentration and grain size. The steel body is heat-treated to achieve a Rockwell hardness of approximately HRC 38-42, balancing toughness and durability. This is typical for industrial PDC drag bits used in non-oilfield drilling contexts where cost efficiency and longevity are prioritized.

Buyers include regional water well contractors, geothermal project developers, and civil engineering firms in Southeast Asia, Africa, and Latin America. The bits are supplied loose or in wooden crates with foam padding, with packaging designed to prevent cutter damage during transit. Lead times are typically 15 to 25 days after order confirmation, and shipping is usually FOB Qingdao or Lianyungang. Minimum order quantities are negotiated per project size, and custom cutter layouts are available upon request.

Linqing City Ruilong Drill Co., Ltd. is a manufacturer based in Linqing, Shandong Province, China, specializing in PDC drill bits for water well and geothermal applications. The company has been producing these tools for over two decades, with a focus on engineering bits for non-oilfield drilling environments. Their facility includes CNC machining, cutter bonding stations, and quality inspection zones, but no public data confirms certifications, export volume, or client lists.

The supplier responds to inquiries with technical guidance on cutter selection based on formation type and borehole size, indicating active engagement with buyers. There is no verified information on workforce size, annual production capacity, or third-party audits. Their trust tier is listed as harbor, suggesting basic verification of business registration but no independent quality or compliance certification. All claims about performance or longevity are based on operational experience, not third-party testing.
