Tricone bit,steel tooth tricone bit,rock bit,steel tooth tricone rock bit,non-sealed bearing bit
1.This type of bits are used in low press resistance soft to medium formation,shales,clay,salt,etc.,It can work in a high RPM and low WOB with fast drilling speed.
2. Surface of cones and teeth are hard enhanced to extend the working life of bit.
3. Teeth distributed optimal design largely improve the working efficiency of breaking down.
