Shank Adapter / Striking Bar - Critical Rock Drilling Component
High-Strength Alloy Steel, High Fatigue Resistance for Mining, Quarrying & Construction
The shank adapter (also called striking bar) is the vital link between your rock drill's hydraulic piston and the drill string. While drill rigs and bits get attention, the shank adapter silently ensures maximum energy transfer—impact, torque, and feed force—directly to the rock. Precision-engineered from high-quality alloy steel, it withstands extreme stress, reduces energy loss, and extends the life of your entire drilling system.
Key Features & Benefits
- High-Strength Alloy Steel - Manufactured from premium-grade alloy steel for exceptional durability under extreme loads
- Precision Energy Transfer - Efficiently transmits high-frequency impact energy, rotational torque, and feed force with minimal loss
- Extreme Fatigue & Wear Resistance - Engineered to endure repeated percussive stress in hard rock conditions
- Secure & Stable Connection - Ensures reliable linkage between the drill rig and drill rods, improving operational safety
- Universal Compatibility - Allows one drill rig to work with various drill bits and rods, reducing inventory complexity
How It Works
The shank adapter sits directly between the rock drill's piston and the first drill rod. It receives high-frequency percussive blows and rotational torque from the drill, then transfers that combined energy down the drill string to the bit. This enables efficient rock fracturing while dampening harmful vibrations that could damage other components.
Industrial Applications
- Mining - Underground and surface drilling for ore body access and blast hole creation
- Quarrying - Dimension stone and aggregate production
- Construction - Foundation drilling, anchor holes, and tunnel excavation
- Geotechnical Engineering - Soil and rock stabilization projects
- Water Well Drilling - Hard rock formations requiring percussive drilling
