High quality tricone rock bits for water well drilling

Tricone rock bit is mainly used in water well drilling and oil exploration. It is devided into 2 types: insert tricone bits and milled teeth tricone bit. Because of superior characteristics they are widely used in soft to very hard rock formations.

Description

Tricone bit is made by steel body and teeth. The steel teeth tricone bit is also called milled teeth tricone rock bit. Milled teeth tricone bit is used for soft to medium hard rocks.
