Die Collar

The Die Collar is a professional external fishing tool used to engage and retrieve dropped tubular objects by cutting threads onto the external wall of the fish. It is widely used in drilling, workover, and well intervention operations where internal fishing methods are not applicable.

The tool is particularly suitable for:

• Drill pipes
• Oil tubing
• Cylindrical fish without internal bore
• Fish with blocked or damaged internal passages

The Die Collar features a long cylindrical integral body structure consisting of:

• Sub connection
• Tapered tap body
• Hardened cutter threads
• Internal cone-shaped fishing section

The cone-shaped internal cutting threads are designed with precision cutting grooves to ensure efficient thread tapping and secure fish engagement during retrieval operations.

Manufactured from heat-treated high-strength alloy steel, the tool provides excellent resistance to wear, torque loads, and severe downhole operating conditions.
