Award and Technology

Our producing and exploration techniques with diamond tools have been widely used. 
Application of Geological Drilling with Diamond Tools was awarded the first prize for National Science and Technique Progress, which is the highest prize awarded to geological engineering up to date.

In recent years, we have made considerable technical progress in improving drilling speed and extending life of diamond tools when drilling special rocks such as hard and solid rocks, fracture and abrasive rocks and soft rocks in coalfield exploration.

Our impregnated diamond drill bits and reaming shells are very popular among users from fields of metallurgy, nonferrous metals, mineral resources, mining, chemistry, construction, and nuclear projects, etc.

As a leading manufacturer of diamond drill bits in Germany, USA, Australia, China, our products are widely sold to US, Canada, Germany, Australia, Singapore, Indonesia, Vietnam, India, Iran, Taiwan and Hong Kong, etc.
