Heavy-Duty, High-Precision HW Recovery Tap – Because Every Rod Counts

In high-value drilling operations, a stuck HW drill rod can cost you hours—sometimes days—of lost productivity. That’s why professionals rely on the HW Recovery Tap, a rugged, precision-built fishing tool designed specifically for HW drill rod retrieval during diamond core drilling and mineral exploration.

Designed to meet the challenges of wireline core drilling in tough geological conditions, this tool ensures fast, secure recovery of rods, barrels, or casings when they get stuck or disconnected downhole.

Key Features & Technical Advantages

Precision Fit for HW Rods (76–89 mm OD)

• Engineered according to GSZ-H standard dimensions, the HW recovery tap ensures a reliable fit and superior recovery performance with HW wireline drill rods.

Self-Tapping Threads + Parallel Wall Design

• Full-depth thread engagement and parallel wall geometry allow the tool to bite cleanly into the stuck rod (“fish”), delivering a strong mechanical hold with reduced risk of slipping.

Durable Alloy Steel Construction

• Made from heat-treated alloy steel and case-hardened to 50–55 HRC, offering long-lasting wear resistance and the toughness needed for deep, demanding recoveries.

Thread Options for All Scenarios

• Available in right-hand and left-hand threads to match various rod types, including reverse-threaded HW systems.

• Choose from male (external thread) or female (internal/bell tap) models based on the recovery situation.

Seamless Integration with Drilling Equipment

• Connects easily with adapter subs, drill strings, and overshot assemblies across standard HW core drilling systems, ensuring easy deployment during emergencies.

Certified for Quality and Reliability

• Manufactured by ISO and CE-certified suppliers, guaranteeing consistent quality and global drilling system compatibility.

Applications

Wireline Core Drilling (HW Size): Recover stuck or broken HW rods, inner tubes, and core barrels during deep-hole or directional drilling.
Mineral Exploration: Designed for use in gold, copper, nickel, and rare earth exploration, where high-value samples and equipment are at risk.
Geotechnical Investigations: Essential for retrieving lost tools in soil testing, foundation drilling, and slope stability studies.
Emergency Downhole Recovery: A must-have fishing tool for every drilling rig dealing with variable ground conditions and complex hole paths.

Why Choose the HW Recovery Tap?

In drilling, stuck rods are inevitable—but downtime doesn’t have to be. The HW Recovery Tap gives you the strength, grip, and reliability you need to retrieve stuck rods quickly and safely. Its field-tested design and hardened construction make it the trusted recovery solution for professional drillers in the harshest environments.

If you use HW drill rods, this tool should be part of your essential gear—minimize downtime, protect your equipment, and keep your drilling operation moving.
