The DERUN Mechanical Drilling Jar is a full‑mechanical tool that can both drill and act as a fishing device to retrieve stuck equipment. It features an industrial‑grade construction that tolerates extreme down‑hole conditions and includes user‑friendly controls for quick transition between drilling and fishing modes. Adjustable settings allow the jar to operate at various drilling depths and pressures. The tool generates an upward jarring motion to release trapped tools, reducing non‑productive time.
The jar is typically forged from AISI 4140 alloy steel, a material standard for high‑strength down‑hole equipment. Typical hardness for this grade lies between 30 - 35 HRC, providing resistance to wear and impact. In the drilling industry, mechanical jars of this class are expected to deliver a maximum tensile load of around 1.5 MN and a working torque near 15 kNm, aligning with the performance of comparable products. The design complies with common offshore safety standards.
Primary users are oil‑field service companies and mining contractors that require reliable tool‑release solutions. The supplier offers flexible minimum order quantities and ships under FOB or CIF terms, allowing buyers to choose the most suitable logistics arrangement. Certifications listed include ISO and SGS, which should be verified with the supplier before purchase. Payment conditions and detailed lead times are not disclosed in the listing and must be confirmed directly.

Before placing an order, verify that the jar’s material grade, heat treatment records and certification copies (ISO, SGS) are authentic and match the specifications described. Request a recent mill test report and, if possible, a sample for mechanical testing to ensure it meets the required tensile and torque capacities for your wells.
Confirm the logistics details early: ask the supplier which Incoterm (FOB or CIF) will apply, the expected lead time from order confirmation to shipment, and the accepted payment methods such as T/T or L/C. Clarify container loading plans and whether the jars are shipped individually or consolidated with other equipment.
Arrange for an independent inspection at the point of loading or upon arrival, focusing on dimensions, material markings and visual condition of the jar. Ensure the supplier can provide a packing list, certificate of origin and any required export documentation to facilitate customs clearance in the destination country.
