CIR70-1 DTH BIT
Core Characteristics

CIR DTH bits are engineered to deliver exceptional performance and long-lasting durability, with a design tailored specifically to endure the harsh conditions of drilling operations. Their robust structural layout enables them to effectively withstand intense impact forces and resist wear caused by abrasive rock formations.
Careful selection of materials and adoption of advanced processing techniques not only extend the service life of the bits but also ensure consistent and efficient drilling performance. This makes CIR DTH bits a dependable choice for a wide variety of rock drilling applications.
The core characteristics of CIR DTH bits are as follows:

  • High-Performance Alloy Buttons: Premium carbide buttons are fitted on these bits, and their layout is strategically optimized to maximize rock-breaking efficiency and boost wear resistance. This thoughtful design effectively extends the operational life of the bits when used in tough drilling conditions.
  • High-Grade Alloy Steel Skirts: The skirt component of each CIR DTH bit is made from top-quality alloy steel, which provides excellent structural strength and rigidity. This allows the bits to handle various mechanical stresses during drilling while maintaining the straightness and precision of the borehole.
  • Complete Size Specifications & Wide Compatibility: CIR DTH bits are available in a full range of sizes and specifications, and they are compatible with most mainstream DTH hammers on the market-including those equipped with DHD shank systems. This ensures that the bits can effectively meet the diverse needs of different drilling projects.

 

Applications

 

CIR DTH bits are highly versatile drilling tools, designed primarily for scenarios where efficient and precise penetration of hard rock is a key requirement. Their robust construction and optimized performance ensure excellent reliability across various geological conditions, making them an indispensable tool for many demanding drilling projects.

 

The main application scenarios of CIR DTH bits include:

  • Mining Industry: These bits are widely used in both open-pit and underground mines for blast hole drilling, mineral exploration, and pre-splitting operations. They help to improve the efficiency of ore extraction and enhance the overall productivity of mining operations.
  • Quarrying Operations: Ideal for drilling precise holes in quarries, these bits support rock fragmentation, aggregate production, and dimensional stone extraction. They ensure stable and efficient operation, reducing downtime and improving the quality of output.
  • Water Well Drilling: Employed in drilling boreholes to access groundwater resources, these bits meet the water supply needs of agriculture, industrial production, and residential use. Their reliable performance guarantees the smooth progress of water well drilling projects.
  • Geothermal Well Drilling: These bits play a critical role in geothermal energy development projects, where drilling through various hard rock formations at great depths is necessary. They can adapt to the complex geological conditions of deep drilling while maintaining efficient penetration rates.
  • Foundation Piling Projects: In construction projects, these bits are used to drill holes for piles that support heavy structures such as high-rise buildings and bridges. Even in challenging ground conditions, they ensure stable and secure foundations, safeguarding the structural safety of constructions.
  • General Construction Works: Applied in various civil engineering projects, including site preparation, trenching, road construction, and other rock excavation tasks. These bits can adapt to diverse construction environments and efficiently meet different drilling requirements.
