T45 Retrac Top Hammer Drill Bits With Tungsten Carbide Insert For Rock Drilling
Top hammer Drill bits
The top hammer rock drilling bit is mainly used for blasting hole excavation of open pit rock drilling, underground mining, tunnelling and other infrastructure projects. The connection mode is mainly T-threaded connection and R-threaded connection. The top hammer hydraulic rock drilling rods equipped with drilling rigs and open-air drilling rigs are used to receive the energy transmitted by the rock drill to achieve the effect of breaking the rock.
At present, the most used in engineering is the spherical bit and the ballistic bit. Due to the special working environment of the thread bit, we require that the thread drill bit should have high wear resistance and impact resistance, and have sufficient toughness to cope with the complicated and harsh working environment. Our rock drilling bit is made of high-quality special steel, the alloy head is made of high-strength and toughness wear-resistant alloy, and the whole processing adopts special surface treatment, thus ensuring that our bit is more durable and has higher fatigue resistance.
Applications of rock drilling tools
• Underground mining and surface mining
• Long hole drilling
• Bench mining and production mining
• Granite, Basalt, Limestone rock etc.
Competitive Advantage
• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
Production Process:
1. Raw material 2. Making bits body 3. Making bit face 4. Heat-treatment 5. Package.
