 IV,Coating Rock-bit for delivery

 
V. Derivative product
Mature technology of mining rock-bit has been introduced into the construction field to develop the combined bit and its related product for large scale project. The 800-3000mm large combined cutter-bit have achieved excellent performance in piers, cofferdams and tunnels' drilling construction.

 
"Quality first,reputation above all" is our forever business principle. We serve the international market with first class quality product and update service.
