The Dongying Lake Fixed Diameter Hole Opener is a downhole tool used to enlarge pre-drilled holes in oil and gas formations, typically after cone bit drilling. It is designed for both onshore and offshore applications and is available in three cutter types: SM for soft to medium formations, MH for medium to hard formations, and XH for hard formations. The tool is mounted above the cone bit or used as a standalone reamer to achieve consistent borehole diameter.
The tool body is constructed from high-strength alloy steel with tungsten carbide inserts on the cutting surfaces. Standard diameters range from 127 mm to 311 mm, with tolerances of ±1.5 mm. The cutting structure is engineered for controlled abrasion rather than impact, reducing the risk of formation damage. Typical service life depends on formation hardness and rotational speed, with standard operating parameters between 60 and 120 RPM.
This product is purchased by drilling contractors, oilfield service companies, and exploration firms operating in Asia, the Middle East, and Africa. Orders are typically placed for bulk quantities to support multi-well campaigns. Packaging is in steel crates with protective coatings to prevent corrosion during ocean transport. Trade terms such as FOB Qingdao or CIF Port of Discharge are standard, but MOQ and lead time are not stated and must be confirmed directly.

Sourcing Fixed Diameter Hole Opener from Dongying Lake Petroleum Technology co.,ltd - China Import Guide
Verify the cutter type matches your formation hardness before ordering. Request a detailed specification sheet for the exact diameter, thread type, and carbide grade. Confirm that the tool has been pressure-tested and that each unit is marked with a unique serial number for traceability.
Confirm the Incoterms - commonly FOB Qingdao or CIF destination port - and lead time, which may range from 15 to 45 days depending on production backlog. Clarify whether the supplier provides installation guidance, spare parts, or repair services. Ensure packaging meets IMO standards for marine transport to prevent corrosion.
Inspect tools upon arrival for damage, corrosion, or missing components. Use a caliper to verify the diameter matches the ordered size. Check that cutting inserts are securely seated and free of cracks. Request a certificate of conformity and a test report for each batch. Retain samples for future reference if failure occurs in the field.
