The QJK Type Drilling Jar from Shandong Saigao Group Corporation is a fully mechanical tool designed to deliver controlled impact force during drilling operations in oil, gas, and mineral exploration. Unlike hydraulic jars, it operates without fluid pressure, relying on mechanical sliding components to generate upward or downward strikes. The tool is built for reliability in deep boreholes where hydraulic systems may fail due to contamination or pressure loss.
The body is constructed from high-strength alloy steel, heat-treated to withstand repeated high-energy impacts. Internal components include a sliding mandrel, spring stack, and impact anvil, all engineered for consistent energy transfer. Adjustable settings allow operators to modify the force of impact by changing the tension on the spring assembly. The tool is rated for use in temperatures ranging from -20°C to 120°C and is compatible with standard 2-7/8 inch to 6-5/8 inch drill pipe threads.
This drilling jar is used primarily by drilling contractors operating in hard rock formations, deep wells, and stuck pipe recovery scenarios. Buyers include oilfield service companies, mining drill rig operators, and equipment rental firms. The tool is typically ordered as a complete assembly, with no separate parts sold. Delivery is FOB Qingdao or Lianyungang, with lead times of 30 to 60 days. Buyers should confirm thread type, length, and weight before ordering, as these vary by model.

Sourcing Drilling jar from Shandong Saigao Group Corporation - China Import Guide
Before ordering, confirm the thread size and type match your drill pipe. Request a dimensional drawing and weight specification for your specific model. Verify that the tool has been tested for impact resistance and that internal components are free of manufacturing defects. Do not accept tools without visible serial numbers or inspection marks, as traceability is critical for safety compliance.
Lead time is typically 30 to 60 days, as these are custom-assembled tools. FOB Qingdao or Lianyungang is standard, but incoterms must be confirmed in writing. Payment terms are usually 30% advance and 70% before shipment. Request a packing list with each component itemized and a certificate of conformity. Ensure the tool is packed in a rigid crate with internal foam padding to prevent damage during transit.
Upon receipt, inspect the tool for surface cracks, misaligned components, or signs of corrosion. Perform a dry cycle test by manually sliding the mandrel to ensure smooth operation. If the tool includes a torque wrench for spring adjustment, verify it is calibrated. Retain all packaging and documentation for at least one year. Request a field test report from the supplier if the tool will be used in high-risk operations.
