Product Description
Rock Drilling Tri-cone Bits

Rock drilling tri-cone bits are mainly used for rock stripping and mining in open pit mine.
According to the different requirements of clients, our company designs various products, including milled tooth bits for soft rock and insert bits for very hard rock.

The tungsten carbide tooth is divided into sphere tooth and conical tooth based on different applications.


ZZ HARDMETAL -DRILL BRANCH is a member of Chinese Drill Steel & Drill Tools Association.We are doing continuous technical communication with the laboratories focusing on mining, drilling and tunneling of Chinese famous universities, such as the Drilling Research Laboratory of China University of Geosciences and the Institute of Forming Technology & equipment of Shanghai Jiao Tong University. In the meantime, we closely cooperate with the professional research institutions, Changsha Institute of Mining Research and China Coal Technology & engineering group Shanghai Research Institute. 
We integrated the top manufactures of Chinese Drill Steel & Drill Tools Association and keep good business relationship with international famous enterprises.
