Applications
The MTH Rock Drilling Bit is engineered for diverse drilling applications including:
- Underground mining operations
- Tunneling projects
- Quarrying activities
- Construction sites
Its high-quality materials ensure durability and longevity, making it ideal for long-term projects. The enhanced heat treatment process increases strength and hardness, enabling high-pressure drilling performance. Two flushing holes facilitate efficient debris removal during operation.
Compatible with hydraulic drilling rigs, these bits are widely used in tunnel construction, large-scale mining operations (both open and underground), and large-section tunnel advances in metal mines.
Packing and Shipping
