How do DTH drilling tools perform in complex formations such as urban metro projects and bridge piling foundations?

Our full range of DTH drilling tools features high-strength alloy buttons and optimized air-flow channel designs. They are suitable for a wide range of formations, including sand, gravel, cobble layers, and hard rock, delivering stable penetration rates and reliable wear resistance. These tools are widely applied in foundation piling, urban infrastructure, and tunneling projects with complex geological conditions.

For open-pit mining in granite or basalt, which is more cost-effective: top hammer or DTH drilling? What are the key selection factors?

For hard rock mining applications such as granite and basalt, DTH drilling systems are generally recommended for hole diameters of 90-152mm, offering higher rock-breaking efficiency and faster penetration rates. Top hammer systems are typically more suitable for medium-hard formations and hole diameters up to 102mm. Key selection factors include rock hardness, hole diameter, bench height, and blasting design requirements.

Do you offer application-specific DTH bits and hammers for different scenarios?

Yes. We offer application-specific DTH bit and hammer solutions for scenarios such as retaining wall foundations, urban road construction, and bridge projects.

Available options include:

Button types: spherical buttons, ballistic buttons
Bit face designs: flat face, concave face, convex face

Special wear-resistant coatings

These configurations allow the tools to be matched to specific formation conditions, helping achieve reliable drilling performance and extended service life.
