WhatsApp: 8615515833787 WeChat: 15515833787Product Name: Fishing External Taper Tap (Oil Drilling Internal Fishing Tool)
Material: 40CrNiMoA / 35CrMo / 20CrMnTi alloy steel, quenched & tempered, HRC28–32, tensile strength ≥980MPa, impact toughness ≥60J/cm², nitrided surface for wear and corrosion resistance. Complies with API 7-1 and GB/T 22245-2018 standards.
Specification: Tapered structure with upper sub, cone body, and external fishing thread. Standard taper 1:16 (customizable 1:12). Size range Φ42–Φ219mm, tolerance ≤±0.05mm, thread accuracy up to 6H. Custom sizes available.
Connection Type: API standard threaded connection with CNC precision machining for tight sealing; some models support quick connection.
Features: High strength and toughness, extrusion-type thread engagement without cutting, smooth run-in, high alignment efficiency, high fishing success rate (≥98%), suitable for complex downhole conditions. Easy operation and reliable disengagement when needed.
Applications: Oil & gas drilling, geological and mining drilling, and water wells. Used for internal fishing of pipes, drill rods, casing, and broken downhole tools in both onshore and offshore operations.
Packaging: Export-standard wooden case with shock-proof and anti-corrosion protection; cone section individually protected.
MOQ: 5 pcs
Delivery Time: 7–15 days (3–7 days for stock)
Payment Terms: T/T or L/C, negotiable.
We provide full-spec customization for fishing external taper taps based on downhole conditions, fish type (internal bore, irregular bore, etc.), bore size, and operational requirements. Materials (40CrNiMoA / 35CrMo / 20CrMnTi, etc.), cone body dimensions, taper ratio (standard 1:16, customizable to 1:12 or other), fishing thread type (standard, trapezoidal, or serrated), length, and connection thread specifications can all be customized for complex conditions such as high temperature, high pressure, corrosion, and sand sticking.
We also offer professional engineering consultation to optimize structure design and material selection. For highly corrosive environments, enhanced anti-corrosion treatment is available; for sand sticking conditions, thread profile can be optimized to improve grip strength. Bulk customization enjoys preferential pricing, along with dedicated NDT inspection reports and material certificates to ensure quality compliance.

Special Falling Objects/Downhole Working Conditions (e.g., Falling Objects with Special Inner Holes, High Corrosion Scenarios) |
✔High-strength alloy material, excellent durability:Made of 40CrNiMoA and 35CrMo alloy steel with quenching and tempering treatment. High hardness, tensile strength, and impact toughness, plus nitriding surface treatment for improved wear and corrosion resistance. Suitable for high-pressure, impact, sand abrasion, and corrosive downhole conditions with long service life and reduced replacement cost.
✔Tapered structure + extrusion fishing design, high efficiency:Standard 1:16 taper ensures fast alignment with internal bore. Extrusion-type thread design enables quick bite without cutting. High engagement strength and fishing success rate (≥98%), effectively preventing fish loss during operation.
✔Precision structure, easy and flexible operation:Compact design with high dimensional accuracy (≤±0.05mm). Marked upper sub for easy identification and operation. Smooth running, fast engagement and release, improving safety and efficiency.
✔Wide adaptability:Standard range Φ42–Φ219mm with full customization available for material, thread type, taper, and size to suit various internal bore fishing conditions in oil, gas, and drilling operations.
✔International standard quality:Manufactured under API 7-1 and ISO 9001 systems with full UT/MT inspection and certified reports, ensuring safe and reliable performance in complex downhole environments.
The fishing external taper tap is widely used in oil, gas, geological, coal, and water well drilling operations. It is designed for internal fishing of tubular components such as drill pipes, casing, and tubing, especially for objects with internal bores such as broken pipes, tool joints, downhole tools, and casing fragments. It effectively handles downhole issues such as sticking, dropping, breaking, and sand jamming, helping restore normal drilling operations.
Typical applications include onshore and offshore oilfield fishing, deep geological drilling recovery, coal mine drilling operations, water well pipe recovery, and directional drilling fishing. It is suitable for complex downhole conditions such as high temperature, high pressure, corrosion, well deviation, and sand sticking, making it an essential emergency fishing tool to reduce downtime, lower costs, and ensure safe and efficient operations.
