We are a leading manufacturer of rock drilling tools located in Changsha, Hunan, China, with 20 years of experience in producing DTH hammers, bits, drill pipes, and related equipment. Our high-quality products, professional service, and competitive prices have earned us an excellent reputation among customers worldwide, including France, Spain, Italy, South Africa, Australia, Iran, and Malaysia.

RC (Reverse Circulation) drilling utilizes dual-wall rods with inner and outer tubes. Compressed air flows through the annulus to power the hammer and bit, while rock fragments are collected in the inner tube and returned to the surface for sampling. This system is widely used in:

• Underground mining and quarries
• Hydraulic and hydro-power engineering
• Water well drilling and mineral exploration
• Anchoring hole drilling and geothermal engineering
• Subway excavation and civil engineering projects

• Initial inspection at production start
• Sampling inspection during processing
• Full quality inspection between processes
• Final inspection before shipping

Our hammers are manufactured from high-quality steel with all components undergoing strict inspection before shipping. We provide prompt responses to all customer feedback and suggestions.
