Product highlights:
1. External Thread Tapping: Uniquely cuts threads onto the fish’s outer wall, enabling retrieval where internal tools fail.
2. Boreless Object Recovery: Critical for fishing cylindrical objects lacking an inner bore(e.g., solid junk) or tubulars with obstructed/internal damaged bores.
3. Monoblock Construction: Features a long cylindrical integral structure combining a sturdy Sub (connection point) and a Tap Body with precision cutting threads in its cone-shaped interior.
4. High-Strength Alloy Build: Manufactured from high-strength alloy steel, heat-treated for maximum toughness in abrasive downhole environments.
5. Optimized Cutting Threads: Internal tapered threads include cutting grooves engineered to efficiently form clean, load-bearing threads on external fish surfaces.
6. Tapered Engagement: The conical design ensures progressive, secure biting into the fish as torque increases.
Overview of Die Collar:
The Die Collar (also known as a Skirted Taper Tap) is a specialized external catch fishing tool designed to recover dropped tubular objects like drill pipes, casings, and oil tubing. Unlike internal fishing tools, it engages by tapping threads onto the external surface of the "fish" (stuck object). This makes it indispensable for retrieving cylindrical items without an inner bore or those with a severely stuck/internal damaged bore. As a robust downhole tool, it integrates with standard drilling tools assemblies for efficient wellbore intervention.
Advantages of Die Collar:
✅Solves "No-Bore" Challenges: Retrieves objects inaccessible to internal fishing tools (e.g., solid fish, collapsed tubing).
✅Secure External Grip: Creates torque-resistant threaded connections directly on the fish’s OD, minimizing slippage risk.
✅Downhole Durability:High-strength alloy construction withstands extreme impacts, abrasion, and high torque common in fishing operations.
✅Operational Versatility: Compatible with standard drilling tools (drill collars, workstrings) for flexible deployment.
✅Precision Thread Cutting:Cutting grooves in hardened threads ensure efficient thread formation even on hardened or irregular surfaces.
✅Robust One-Piece Design:Integral structure eliminates weak points, enhancing reliability as a downhole tool during aggressive fishing.
✅Reduces Fishing Complexity: Provides a direct solution for external recovery, avoiding multiple tool runs or milling operations.
