Boart HD 155 High Grade Alloy Steel Shank Adapter With 580 Length And R32 / T38 Thread Type For Drifting And Mining
Boart HD 155 Rock Drill Shank Adapters provide high performance solutions for drifting and tunneling applications. In the demanding world of rock drilling, these adapters serve as the critical link between the rock drill and the drill string. Engineered for maximum energy transfer and durability, they are the backbone of efficient underground mining and tunneling operations.
Key Technical Specifications
The shank adapter must endure constant high frequency impacts and intense rotational torque. To prevent premature failure, our HD 155 series is manufactured with premium alloy steel, ensuring:
Superior Fracture Toughness : Resists cracking under extreme percussive force.
Zero Plastic Deformation : Maintains structural integrity and thread alignment even under high load cycles.
Wear Resistance : Specialized heat treatment to extend the service life of splines and threads.
Choosing the Right Interface : Male vs. Female Adapters
Understanding your site conditions is crucial for selecting the optimal configuration. While both serve the same core purpose, their mechanical advantages differ:
Male Threaded Shank Adapters (Industry Standard)
Male adapters are the preferred choice for the majority of drifting, tunneling, and long hole extension drilling.
Best for : High stress environments where maximum power transmission is required.
Advantage : Better handling of bending stresses during deep hole drilling.
Female adapters are specialized components designed for restricted environments.
Best for : Operations where drilling space is limited or when using specific drill rig configurations.
Advantage : Compact design that allows for efficient tool changes in tight headings.

Why Upgrade Your Drifting Equipment?
The efficiency of your percussive drilling depends entirely on how much energy reaches the bit. A worn or low quality shank adapter leads to energy loss, increased vibration, and potential damage to the rock drill's hammer.
Our Boart HD 155 Compatible Adapters Offer :
Optimized Energy Transfer : Increases penetration rates (ROP).
Universal Compatibility : Seamlessly fits HD 155 series hydraulic drifters.
Cost Per Meter Efficiency : Longer service life means fewer replacements and less downtime.
