Taper Tap
Heavy-Duty Taper Tap for Internal Fishing Operations
GREAT Taper Tap is a professional internal catch fishing tool designed for retrieving dropped tubular objects such as drill pipes, tubing, and casing strings. The tool engages the fish by cutting and tapping threads directly onto the internal surface of the dropped object, providing a strong and reliable connection during fishing operations.
Manufactured from heat-treated high-strength alloy steel and equipped with hardened cutting threads, the Taper Tap delivers dependable performance in demanding drilling and workover environments.
Application
- Drill Pipe Fishing
- Tubing Retrieval
- Casing Fishing Operations
- Downhole Recovery Operations
- Workover & Well Intervention
Key Advantages
- Strong internal gripping capability
- Effective for fishing tubulars with couplings
- Hardened cutting threads for efficient engagement
- Suitable for right-hand and left-hand operations
- Durable high-strength construction
The Taper Tap is a specialized internal fishing tool used to engage and retrieve dropped tubular objects by cutting tapered threads into the fish surface. The tool is widely used for fishing drill pipes, tubing, casing, and other tubular components encountered during drilling and workover operations.
The tapered threaded body allows the tool to securely bite into the internal surface of the fish while transmitting pulling and torque loads during retrieval operations. The tool is especially effective when fishing tubular objects with couplings.
The Taper Tap can be used with:
- Right-hand threaded drill strings
- Left-hand threaded drill strings
- Fishing assemblies
- Jars and workover tools
The cutting threads are hardened and designed with cutting grooves to improve penetration and ensure reliable thread tapping into the fish. This design provides strong engagement while minimizing slippage during retrieval.
Manufactured from premium alloy steel and heat treated for maximum strength and durability, GREAT Taper Taps are engineered for severe downhole service conditions.
