Hammer Bits
Hammer bits are specially designed drill bits used with air hammers (DTH hammers) in Horizontal Directional Drilling (HDD). These bits feature tungsten carbide inserts and a rugged construction to withstand the extreme impact and rotational forces required to break through hard rock formations such as granite, basalt, and limestone.
Key Features
- Tungsten Carbide Inserts – Exceptional durability and cutting efficiency.
- Optimized Face Designs – Various profiles for different rock conditions.
- Air Flushing System – Removes cuttings efficiently to maintain drilling speed.
- High-Impact Resistance – Designed to withstand extreme percussive forces.
- Threaded Connection – Secure fit for seamless integration with air hammers.
Types of Hammer Bits
- Convex Face Bit – Best for medium to hard rock, providing excellent stability and penetration.
- Flat Face Bit – Ideal for abrasive rock formations, reducing bit wear.
- Concave Face Bit – Enhances control and hole straightness in fractured rock.
- Step/Chisel Bit – Designed for fractured or layered formations, improving breaking efficiency.
Advantages
- Fast Drilling Speed – Breaks through hard rock faster than conventional HDD bits.
- Longer Service Life – High-strength materials extend bit lifespan.
- Efficient Rock Removal – Air-assisted flushing prevents clogging.
- Reduced Equipment Stress – Lower torque requirements reduce strain on drill pipes.
- Versatile Applications – Suitable for various HDD projects in challenging terrains.
